retrieval.<br><br>The first part of my work focuses on efficient inference serving of tree ensemble models. Tree structures are inherently not cache friendly and their traversal incurs random I\/Os. We developed two systems - Blockset (Block Aligned Serialized Trees) and T-REX (Tree Rectangles).<br><br>Blockset improves inference latency in the scenario where the model doesn\u2019t fit in memory. It introduces the concept of selective access for tree ensembles in which only the parts of the model needed for inference are deserialized and loaded into memory. It uses principles from external memory algorithms to rearrange tree nodes in a block aligned format to minimize the number of I\/Os needed for inference. T-REX optimizes inference latency for both in-memory inference as well as inference when the model doesn\u2019t fit in memory. T-REX reformulates decision tree traversal as hyperrectangle enclosure queries using the fact that decision trees partition the space into convex hyperrectangles.  The test points are then queried for enclosure inside the hyperrectangles. In doing random I\/O is traded for additional computation.<br><br>The second part of my work focuses on efficient deep learning model storage. We implemented a deep learning model repository that requires fine-grained access to individual tensors in models. This is useful in applications such as transfer learning, where individual tensors in layers are transferred from one model to another. We\u2019re currently working on caching and prefetching popular tensors based on application level hints.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=665304\">Meghana Madhyastha<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14152216000295444845\">Johns Hopkins University<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess309\" ssid=\"drs123\"><span style=\"display: none;\"><!-- cal-file sess290--drs123.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs123\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The gap between alerts and early detection remains wide open because noisy attack attempts and unreliable alerts mask real attacks from humans. This dissertation brings together: 1) attack patterns mining driven by real security incidents, 2) probabilistic graphical models linking patterns with runtime alerts, and 3) an in vivo testbed which embeds a honeypot in a live Science DMZ network for realistic assessment. Traditional techniques that seek specific attack signatures or anomalies are ineffective because defenders only see a partial view of ongoing attacks while having to wrestle with unreliable alerts and heavy background noise of attack attempts. In contrast, our principle objective is to reinforce scant, incomplete evidence of potential attacks with the ground truth of past security incidents. We evaluated our system, Cyborg's, accuracy, and performance in three experiments at the National Center for Supercomputing Applications at the University of Illinois. Our deployment stops 8 out of 10 replayed attacks before system integrity violation and all ten before data exfiltration. In addition, we discovered and stopped a family of ransomware attacks before the data breach. During the period of deployment, this thesis resulted in a honeypot that collected 15 billion attack attempts (the world's largest publicly analyzed dataset) for analytics.

It allowed for new and better solutions to the problem of low resource utilization, an issue that has been known in data centers for decades. The problem persists as the frequently changing resource availability cannot be addressed entirely with techniques such as persistent cloud allocations and batch jobs. The elastic fine-grained tasking and largely unconstrained scheduling of FaaS create new opportunities. Still, modern serverless platforms struggle to achieve the high performance needed for the most demanding and latency-critical workloads. Furthermore, many applications cannot be \u201cFaaSified\u201d without non-negligible loss in performance, and the short and stateless functions employed in FaaS must be easy to program, debug, and optimize. By solving the fundamental performance challenges of FaaS, we can build a fast and efficient programming model that brings innovative cloud techniques into HPC data centers, allowing users to benefit from pay-as-you-go billing and helping operators to decrease running costs and their environmental impact. My PhD research attempts to bridge the gap between high-performance programming and modern FaaS computing frameworks. I have been working on tailored solutions for different levels of the FaaS computing stack: from computing and network devices to high-level optimizations and efficient system designs.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=727473\">Marcin Copik<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8651363363052116427\">ETH Z\u00fcrich<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess310\" ssid=\"drs121\"><span style=\"display: none;\"><!-- cal-file sess290--drs121.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs121\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

To address the dynamic availability of modern computing resources as well as the multiple costs involved in computing, we presented extensions of our framework as DELTA+ which demonstrated the ability for resource provisioning and multidimensional compute costs. <br><br>To bring this idea of resource abstraction via serverless into the rapidly growing field of federated learning, we developed and released FLoX: Federated Learning on funcX. This framework was built from the ground up around a serverless computing paradigm with experimentation and usability in mind. Extending the lessons learned from DELTA around self-adaptive systems, we began exploring the potential of automating tradeoffs found in FLoX and federated learning in general. <br><br>Looking ahead, we are developing FLoX into a much more robust framework to enable the use of a wide range of computing resources while abstracting away the difficulties of configuring and optimizing a federated learning experiment. Additionally, we are actively working on a re-release of DELTA with all extensions combined into one framework with updated cost and execution time predictors and complete resource provisioning ability. Finally, we are designing an integration between FLoX and DELTA that will enable serverless-based FL to automatically place each component of an FL flow and move data as necessary to best use the available resources.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=010573\">Matt Baughman<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=4758609107779219141\">University of Chicago<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess309\" ssid=\"drs127\"><span style=\"display: none;\"><!-- cal-file sess290--drs127.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs127\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

With the ever-increasing computing power such as the new generation of exascale (one exaflop or a billion billion calculations per second) supercomputers, the gap between computing power and limited storage capacity and I\/O bandwidth has become a major challenge for scientists and engineers. Large-scale scientific simulations on parallel computers can generate extremely large amounts of data that are highly compute and storage intensive. This study will introduce data reduction techniques as a promising solution to significantly reduce the data sizes while maintaining high data fidelity for post-analyses in HPC applications. This study can be categorized into mainly four scenarios: (1) A ratio-quality model that makes lossy compression predictable; (2) advanced parallel write solution with async-I\/O; (3) in-situ data reduction for scientific applications; and (4) in-situ data reduction for large-scale machine learning.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_020093.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_020093.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=020093\">Sian Jin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=817396808794328686\">Indiana University<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess310\" ssid=\"drs111\"><span style=\"display: none;\"><!-- cal-file sess290--drs111.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs111\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

In-situ visualization, the visualization of simulation or experiment data as it is generated, enables simulation steering and experiment control, which helps scientists gain an intuitive understanding of the studied phenomena. Such data exploration requires interactive visualization with smooth viewpoint changes and zooming to convey depth perception and spatial understanding. As data sizes increase, this becomes increasingly challenging. <br><br>This thesis presents an end-to-end solution for interactive in-situ visualization on distributed computers based on novel extensions to the Volumetric Depth Image (VDI) representation. VDIs are view-dependent, compact representations of volume data that can be rendered faster than the original data.<br><br>We propose the first algorithm to generate VDIs on distributed 3D data, using sort-last parallel compositing to scale to large data sizes. Scalability is achieved by a novel compact in-memory representation of VDIs that exploits sparsity and optimizes performance. We also propose a low-latency architecture for sharing data and hardware resources with a running simulation. The resulting VDI is streamed for remote interactive visualization.<br><br>We provide a novel raycasting algorithm for rendering streamed VDIs, significantly outperforming existing solutions. We exploit properties of perspective projection to minimize calculations in the GPU kernel and leverage spatial smoothness in the data to minimize memory accesses.<br><br>The quality and performance of the approach are evaluated on multiple datasets, showing that the approach outperforms state-of-the-art techniques for visualizing large distributed volume data. The contributions are implemented as extensions to established open-source tools.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=448093\">Aryaman Gupta<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13300485966348853797\">Technical University Dresden<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16197887626334287129\">Center for Systems Biology Dresden (CSBD)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess309\" ssid=\"drs115\"><span style=\"display: none;\"><!-- cal-file sess290--drs115.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs115\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We work closely with these communities to leverage high-performance computing (HPC), big data analytics, and artificial intelligence\/machine learning (AI\/ML) to increase and accelerate their workflows\u2019 productivity. Our work addresses the new challenges brought about by this optimization process.<br><br>We identify three main challenges in these workflows: i) they integrate AI\/ML methods with limited transparency and include many interoperable components (data and applications) that are hard to trace and reuse to reproduce results; ii) they hide the complexity of large intermediate data and their overall execution can be affected by the I\/O bandwidth of the underlying infrastructure; and iii) they run on heterogeneous and distributed infrastructure with data and application dependencies that require efficient data management and resource allocation.<br><br>To address these challenges, we provide solutions that leverage the convergence between high-performance and cloud computing. First, we design and develop fine-grained containerized environments that enable data traceability and results explainability by automatically annotating and seamlessly attaching provenance information. Second, since the workflows are already containerized, we integrate them in HPC and native-cloud infrastructure and tune the storage technology to enable better I\/O and data scalability. Finally, we orchestrate the end-to-end execution of workflows, ensuring efficient allocation of infrastructure resources and intermediate data management, and supporting reproducibility and reusability of workflows\u2019 executions.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_876873.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_876873.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=876873\">Paula Olaya<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2281450494390016393\">University of Tennessee<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess310\" ssid=\"drs120\"><span style=\"display: none;\"><!-- cal-file sess290--drs120.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs120\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The diversity of hardware and software stacks adds additional development challenges to high performance simulations. One common development approach is to re-engineer the code for each new target architecture in order to maximize performance. However, this re-engineering effort is no longer practical due to increasing heterogeneous hardware. Adding support for a single family of GPUs alone poses a significant challenge. Supporting each major vendor's hardware and software stacks takes valuable developer time away from optimizing and enhancing simulation capabilities. Moving forward, the community must modernize the code development process in order to achieve the greatest scientific output.<br><br>In this work, we examine the challenges posed by emerging heterogeneous hardware. These challenges include developing performance portable code, leveraging hardware features targeting AI\/ML for HPC applications, and difficulties managing limited I\/O resources while checkpointing. To address these challenges we present a modernization approach for scientific software that ensures the following. Attain high performance and portability across architectures using the Kokkos portability framework in addition to optimizations to memory layout, sorting algorithms, and vectorization. Leverage alternative number formats such as half-precision and fixed-point to maximize usage of the limited memory on GPUs and enable larger simulations. Reduce IO overhead and storage requirements through the identification and elimination of spatial-temporal redundancy in application data.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=744373\">Nigel P.

Upcoming upgrades to accelerators such as the Large Hadron Collider as well as to experiments like ATLAS threaten to render existing CPU-based approaches to track reconstruction insufficient, and the use of massively parallel systems - GPGPUs in particular - is an important opportunity to meet future data processing requirements. In my thesis, I investigate the feasibility of GPGPU-based track reconstruction from performance engineering perspective: I focus on structured analysis of application performance, the development of statistical and analytical models of performance, methods for mitigating the challenges of GPGPU programming, and the design and implementation of novel track reconstruction algorithms. The key contributions of my thesis include the development of novel algorithms for hit clustering, seed finding, and combinatorial Kalman filtering, key parts of the track reconstruction process. These algorithms suffer from significant load imbalance and thread divergence, and I have developed a novel statistical method for estimating the performance effects of this, as well as to guide optimization through thread refinement and coarsening. I have developed a method for the automated design space exploration of data storage methods for magnetic fields, which play a crucial role in track reconstruction. Furthermore, I have developed an evolutionary method for finding layouts for multi-dimensional arrays in hierarchical memory systems. My thesis will be concluded by a comprehensive study of the performance of track reconstruction, as guided by the aforementioned research.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=588493\">Stephen Nicholas Swatman<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9584352740564478296\">University of Amsterdam<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8872953039016464172\">European Organization for Nuclear Research (CERN)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess309\" ssid=\"drs106\"><span style=\"display: none;\"><!-- cal-file sess290--drs106.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs106\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Despite efforts to address it, the gap between them is still widening. This has led to the categorization of many applications as memory-bound kernels.\t<br><br>This dissertation centers on memory-bound kernels, with a particular emphasis on Graphics Processing Units (GPUs), given their rising prevalence in High-Performance Computing (HPC) systems. <br><br>In this dissertation, we initially focus on the evolution trend of GPU development in the last decades. Examples include cooperative groups (i.e., device-wide barriers), asynchronous copy of shared memory (i.e., hardware prefetching), low(er) latency of operations, and larger volume of on-chip resources (register files and L1 cache).<br><br>This dissertation seeks to utilize the latest GPU features to optimize memory-bound kernels. Specifically, we propose extending the kernel's lifetime across the time steps and taking advantage of the large volume of on-chip resources (i.e., register files and scratchpad memory) in reducing or eliminating traffic to the device memory. Furthermore, we champion a minimum level of parallelism to maximize the available on-chip resources.\t<br><br>Based on the strategies, we propose a general execution model for running memory-bound iterative GPU kernels: PERsistent KernelS (PERKS) and a novel temporal blocking method, EBISU. Evaluations have shown outstanding performance in the latest GPU architectures compared with counterpart state-of-the-art implementations.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=927483\">Lingqi Zhang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=804818205258833799\">Tokyo Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess310\" ssid=\"drs103\"><span style=\"display: none;\"><!-- cal-file sess290--drs103.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs103\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

These parameters are determined by constructing and solving a mathematical optimization problem. Ultimately, the goal is to create treatment plans for each patient such that a high dose is delivered to the tumor, while sparing surrounding healthy tissue as much as possible. Solving the optimization problem can be computationally expensive, as it requires both a method to compute the delivered dose in the patient and an algorithm to solve a (in general) constrained and nonlinear optimization problem.<br><br>The goal of this thesis project has been to investigate the use of HPC hardware and methods to accelerate the computational workflow in radiation therapy treatment planning. First, we propose two methods to bring the optimization to HPC hardware using GPU acceleration and distributed computing for dose summation and objective function calculation respectively. We show that our methods achieve competitive performance compared to state-of-the-art libraries and scale well, up to the Amdahl\u2019s law limit.<br><br>Then, we investigate methods to accelerate interior point methods, a popular algorithm for constrained optimization. We investigate the use of iterative Krylov subspace linear solvers to solve Newton systems from interior point methods and show that we can compute solutions in reasonable time for our problems, in spite of extreme ill-conditioning. This approach presents one avenue by which constrained optimization solvers for radiation therapy could be ported to GPU accelerators.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_815693.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_815693.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=815693\">Felix Liu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16872165478857573506\">Raysearch Laboratories<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype118\">Doctoral Showcase<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess310\" ssid=\"drs105\"><span style=\"display: none;\"><!-- cal-file sess290--drs105.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess290--drs105\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Visualization techniques are used to analyze the simulation results in their three-dimensional context.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=752053\">Gregory Abram<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14658713910765412241\">Texas Advanced Computing Center (TACC)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=227063\">Alice Gabriel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11152328118408272449\">University of California San Diego<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=720463\">Francesca Samsel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14658713910765412241\">Texas Advanced Computing Center (TACC)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=408804\">Nico Schliwa<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11866573228040836474\">Ludwig-Maxmilians-Universit\u00e4t M\u00fcnchen<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=508383\">Yinzhi Wang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14658713910765412241\">Texas Advanced Computing Center (TACC)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=051204\">Sean Cunningham<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14658713910765412241\">Texas Advanced Computing Center (TACC)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype135\">Scientific Visualization & Data Analytics Showcase<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess294\" ssid=\"svs102\"><span style=\"display: none;\"><!-- cal-file sess292--svs102.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess292--svs102\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The tour summarizes results from Andrea Ghez's Galactic Center Group: their study of the motions of stars around the Milky Way's central black hole reveals a rich and surprising environment, with hot young stars (coded as purple) where few were expected to be, many orbiting in a common plane; a paucity of cooler old stars (yellow); a population of unexpected \"G-object\" dusty stars (red); and an eclipsing binary star (teal). The black hole itself, shrouded in mystery, is seen only as a tiny faint twinkling radio source.   But the movement of these nearby stars, especially the S0-2 \"hero\" (pale blue ellipse), probe the black hole's gravity, exposing its massive presence.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_085473.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_085473.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=085473\">Kalina M.

Driven by low humidity and high winds, the wildfire spread to over 200,000 acres in nine days, with 87,000 of those acres being burnt in a single 24 hour period. Wildfire simulations and forecasts help decision-makers issue evacuation orders and inform response teams, but these simulations depend on accurate variable inputs to produce trustworthy results. These wildfire visualizations demonstrate new AI tools developed at the National Center for Atmospheric Research (NCAR), which are producing superior wildfire simulation outputs than have been available in the past.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=264463\">Scott Pearse<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14899469141063437275\">National Center for Atmospheric Research (NCAR)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=620114\">Amy DeCastro<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14899469141063437275\">National Center for Atmospheric Research (NCAR)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=720114\">Timothy Juliano<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14899469141063437275\">National Center for Atmospheric Research (NCAR)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype135\">Scientific Visualization & Data Analytics Showcase<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess294\" ssid=\"svs105\"><span style=\"display: none;\"><!-- cal-file sess292--svs105.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess292--svs105\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Our objective is to selectively utilize GPUs for duplicate calculations based on the numerical properties of the sparse matrices to enhance the reliability and performance of linear system solutions. Enabling the ability to rely on the relatively underutilized CPU for fault detection improves scientific applications' ability to efficiently manage their resources on large-scale systems. By leveraging existing fault-checking techniques, we validate calculations and address potential numerical instabilities or precision-related issues during iterative solving. Through extensive experimentation on real hardware, we demonstrate the effectiveness of the conjugate gradient algorithm in providing accurate and reliable solutions for large linear systems.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=266004\">Hayden Estes<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13561866658308260581\">University of Alabama, Huntsville<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu114\"><span style=\"display: none;\"><!-- cal-file sess289--spostu114.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu114\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

For example, the increasingly popular large language models (e.g., ChatGPT) have billions of parameters. While this has led to performance improvements, the performance gains for simple tasks may be unacceptable for the additional cost. We apply residual networks of three different depths and evaluate them extensively on the MedMNIST pneumonia dataset.

Traditional backfilling techniques, such as EASY-backfilling, rely on user-submitted runtime estimates, which can be inaccurate and lead to suboptimal scheduling. This poster presents RL-Backfiller, a novel reinforcement learning (RL) based approach to improve HPC job scheduling. Our method incorporates RL to make better backfilling decisions, independent of user-submitted runtime estimates. We trained RL-Backfiller on the synthetic Lublin-256 workload and tested it on the real SDSC-SP2 1998 workload. We show how RLBackfilling can learn effective backfilling strategies and outperform traditional EASY-backfilling and other heuristic combinations via trial-and-error on existing job traces. Our evaluation results show up to 17x better scheduling performance (based on average bounded job slowdown) compared to EASY-backfilling<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=046804\">Elliot Kolker-Hicks<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1411731814966089758\">University of North Carolina, Charlotte<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu105\"><span style=\"display: none;\"><!-- cal-file sess289--spostu105.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu105\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

One popular approach for actualizing autonomous vehicles is using end-to-end learning, in which a machine learning model is trained on a large data set of real human driving. This poster shows how self-driving consistency can be improved using a Convolutional Neural Network (CNN) to predict current velocity.

To optimize costs, they use a multi-tiered storage approach based on data temperature, storing infrequently accessed (\"cold\") data on cheaper technologies like Blu-ray disks or tape drives, and frequently accessed (\"hot\") data on faster but costlier mediums like Hard Disk Drives or Solid State Drives. Current data migration decisions rely on manual human judgment supported by simple algorithms not suitable for long-term predictions. To address this, our project aims to automate the process by training a deep neural network (DNN) on file metadata to predict data temperature upon upload. The model achieved promising initial results, with a 90.53% general accuracy in predicting data temperature. This automation could significantly improve the management and distribution of the vast research data generated at BNL.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=169804\">Keene Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=971090871307300522\">Northwestern University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=968693\">Ai Kagawa<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5958783247319949560\">Brookhaven National Laboratory<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu113\"><span style=\"display: none;\"><!-- cal-file sess289--spostu113.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu113\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Training a transformer-based model requires the utilization of HPC harnessed through inherent parallelism embedded in processor design, to deliberate modification of neural networks to increase concurrency during training and inference. Our model is the culmination of different performance tests seeking the ideal combination of frameworks and configurations for training a 13-billion-parameter translation model for foreign languages. We performed ETL over the corpus, which involved training a balanced interleaved dataset. We investigated the impact of batch size, learning rate, and different forms of precision on model training time, accuracy, and memory consumption. We use DeepSpeed stage 3 and Huggingface accelerate to parallelize our model. Our model, based on the mT5 architecture, is trained on the mC4 and language-specific datasets, enabling question-answering in the fine-tuning process.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=956804\">Chris Pierre Paul<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1850422148242360821\">Oak Ridge Institute For Science And Education<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2064839953530329817\">Florida State University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=867804\">Leo Phan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1850422148242360821\">Oak Ridge Institute For Science And Education<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13664238375824378139\">George Washington University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu106\"><span style=\"display: none;\"><!-- cal-file sess289--spostu106.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu106\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Previous priority-based language models limit the span of entire threads to a single priority. Given an approaching real-time deadline, tasks are unable to shift to a higher priority in order to match the changing requirements. We design a type system that enforces thread priorities and allows dynamic prioritization, treating priorities as first-class to reduce code complexity. We create a dependency graph-based cost model for our system and define strong well-formedness to exclude unwanted priority inversions. We then prove that programs under our type system produce strongly well-formed graphs.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=009791277865096033\">Marelle Le\u00f3n<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu120\"><span style=\"display: none;\"><!-- cal-file sess289--spostu120.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu120\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Federated Learning~(FL) mitigates this as a decentralized training system where no raw data are communicated across the network to a centralized server. Instead, the machine learning model is trained locally on each device and they send the locally-trained model weights to a central server to aggregate. However, there are critical challenges with FL. Security issues plague FL, such as model poisoning via label flipping. Additionally, there even exist privacy concerns via data leakage by reconstruction of weights. In this work, we apply differential privacy (which adds noise to the model weights before sending across the network) as an added privacy measure to protect sensitive data from being reconstructed. Through this research, we study the effects of differential privacy on FL with respect to security and privacy trade-offs.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=850904\">Adhishree Kathikar<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=817396808794328686\">Indiana University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostu121\"><span style=\"display: none;\"><!-- cal-file sess289--spostu121.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostu121\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We use a comprehensive analytical performance model to analyze how such models could be trained on current systems while maintaining 75% Model FLOPS Utilization (MFU). We first show how tensor offloading alone can be used to dramatically increase the size of trainable LLMs. We analyze performance bottlenecks when scaling on systems up to 16,384 GPUs and with models up to 128T parameters. Our findings suggest that current H100 GPUs with 80 GiB of HBM enabled with 512 GiB of tensor offloading capacity allows scaling to 11T-parameter LLMs; and getting to 128T parameters requires 120 GiB of HBM and 2 TiB of offloading memory, yielding 75%+ MFU, which is uncommon even when training much smaller LLMs today.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=075873\">Mikhail Isaev<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg116\"><span style=\"display: none;\"><!-- cal-file sess289--spostg116.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg116\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, OCT generates approximately 100 GB per flow cell, which complicates storage and data sharing. Data reduction can reduce data complications by reducing the overhead and the amount of data transferred. This work leverages the similarities between layers of OCT images to minimize the data in order to improve compression. This paper evaluates the 5 lossless and 2 lossy state-of-the-art compressors to reduce the OCT data.  The reduction techniques are evaluated to determine which compressor has the most significant compression ratio while maintaining a strong bandwidth and minimal image distortion.  Results show that SZ with frame before pre-processing is able to achieve the highest CR of 204.6x on its higher error bounds. The maximum compression bandwidth SZ on higher error bounds is ~41MB\/s, for decompression bandwidth, it is able to outperform ZFP achieving.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=839993\">Max Faykus<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3939629011957553511\">Clemson University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg125\"><span style=\"display: none;\"><!-- cal-file sess289--spostg125.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg125\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Unfortunately, state-of-the-art floating-point array compressors such as SZ and ZFP require decompression before operations can be performed on the data. In this work, our contribution is to show that compression methods can be designed to allow efficient operations on compressed arrays without having to first decompress. In particular, compression methods that consist of only linear transformations and quantization allow certain operations on compressed arrays without decompression. We develop such a compression method, called PyBlaz, the first compression method we know that can compress arbitrary-dimensional arrays and directly operate on the compressed representation, with all stages running on GPUs.<br><br>In the poster session, I will provide details about each compression step, several compressed-spaced operations, and our ongoing performance and application experiments.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=857504\">Harvey Dam<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13156063078672698007\">University of Utah<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg115\"><span style=\"display: none;\"><!-- cal-file sess289--spostg115.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg115\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Complications can be avoided by using expensive continuous positive airway pressure (CPAP) machines, but physicians cannot identify those at risk. Large language models (LLMs) have recently made impressive advancements in sequence modeling, and clinical applications are quickly emerging. However, the medical relevance of pre-trained LLM latent spaces remains uncertain.<br><br>This study gauges 12 pre-trained clinical LLMs, clustering OSA-related phenotypes and comorbidities (atrial fibrillation, coronary artery disease, heart failure, hypertension, stroke, type 2 diabetes). Using 40 A100 GPUs on NERSC\u2019s Perlmutter, document-level embeddings for 331,793 MIMIC-IV discharge reports were computed for each LLM. K-Means models were ranked by clustering entropy of phenotype classes, guiding model selection. The top models successfully subset patients with similar histories and outcomes. This work will support ongoing OSA research by identifying phenotypes and assist physicians by informing CPAP allocation.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=765804\">Ifrah Khurram<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7186020695629951610\">San Juan Bautista School of Medicine<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg130\"><span style=\"display: none;\"><!-- cal-file sess289--spostg130.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg130\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Critical to the use of ML is the process of splitting datasets into training, validation, and testing subsets to develop and evaluate models. Common practice is to assign these subsets randomly. Although this approach is fast, it only measures a model's capacity to interpolate. These testing errors may be overly optimistic on out-of-scope data; thus, there is a growing need to easily measure performance for extrapolation tasks. To address this issue, we report astartes, an open-source Python package that implements many similarity- and distance-based algorithms to partition data into more challenging splits. This poster focuses on use-cases within cheminformatics. However, astartes operates on arbitrary vectors, so its principals and workflow are generalizable to other ML domains as well. astartes is available via the Python package managers pip and conda and is publicly hosted on GitHub (github.com\/JacksonBurns\/astartes).<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=692704\">Jackson Burns<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10388946747097259651\">Massachusetts Institute of Technology (MIT)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg107\"><span style=\"display: none;\"><!-- cal-file sess289--spostg107.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg107\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Moving from established single-heartbeat technology to longitudinal profiles would require continuous data reflecting a patient's evolving state, methods to extend the temporal domain that could be feasibly computed, and high-throughput resources. Although personalized models can accurately measure 3D hemodynamics over single heartbeats, state-of-the-art methods would require centuries of runtime on leadership-class systems to simulate one day of activity. We are establishing the Longitudinal Hemodynamic Mapping Framework (LHMF), which combines patient-specific models, wearables, and cloud computing to enable the first digital twins that capture longitudinal hemodynamic maps (LHMs). We demonstrate validity through comparison with ground truth data for 750 beats. We applied LHMF to generate the first LHM of coronary arteries spanning 4.5 million heartbeats. LHMF relies on an initial fixed set of representative simulations to enable the computationally tractable creation of LHM over heterogeneous systems.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_066304.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_066304.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=066304\">Cyrus Tanade<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11350818937430738967\">Duke University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg108\"><span style=\"display: none;\"><!-- cal-file sess289--spostg108.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg108\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The increase in high-precision, high-sample-rate time-series data is a challenge to existing database technologies. We have developed a novel technique that utilizes sparse-file support to achieve O(1) time complexity in create, read, update, and delete (CRUD) operations while supporting time granularity down to 1-second. We designed and implemented XStore to be lightweight and offer high performance without the need to maintain an index of the time-series data. We have conducted a detailed evaluation between XStore and existing best-of-breed systems such as MongoDB using synthetic data spanning 20 years, with second granularity, totaling over 5 billion datapoints. Through empirical experiments against MongoDB, XStore achieves 2.5X better latency and delivers up to 3X improvement in throughput.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_185804.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_185804.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=185804\">Lan Nguyen<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg124\"><span style=\"display: none;\"><!-- cal-file sess289--spostg124.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg124\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

At each stage of the algorithm, we maintain a summary of the clustered graph computed from all incremental batches received thus far. As we receive a new batch of nodes and edges, we cluster the new graph and merge new clusters with the previous summary clusters. We use sparse linear algebra to perform these operations. Our algorithm would make it possible to find clusters in very large graphs for which regular graph clustering algorithms could not run due to computation\/communication bottlenecks.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=539283\">Md Taufique Hussain<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=817396808794328686\">Indiana University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg129\"><span style=\"display: none;\"><!-- cal-file sess289--spostg129.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg129\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, the current NetCDF framework and its derived libraries lack efficient support for querying and visualizing data subsets with low memory use and time cost. Therefore, a full-stack solution to handle and display multidimensional data frames in NetCDF must be developed to meet the research needs. In this project, a next-generation full-stack tool, \u201cNetCDFaster,\u201d was developed to accelerate the reading and viewing of NetCDF data. This tool was derived from serial and parallel interfaces built on MPI-IO. The test results showed that processing time and memory usage were significantly improved than conventional methods.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=064804\">Zhenlei Song<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1915623848265844395\">Texas A&M University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg102\"><span style=\"display: none;\"><!-- cal-file sess289--spostg102.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg102\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

While computational capabilities have grown exponentially, I\/O performance has lagged behind. To address this issue, we present an in-transit approach to enable in situ visualization and analysis of large-scale fluid-structure-interaction models on leadership-class systems. We delineate the proposed framework and demonstrate the feasibility of this approach by measuring overhead introduced.

Applications such as compression auto-tuning or lossy compressor selection require a high-throughput, accurate estimation. Prior works that utilize sampling are fast but inaccurate, while approaches which do not use sampling are highly accurate but slow. Through sensitivity analysis we show that sampling a small number of moderately sized data blocks maintains fast data transfer and yields superior estimation accuracy compared to existing sampling approaches, and we use this to construct a new fast and accurate sampling method. In relation to non-sampling techniques, our method results in less than 10% degradation in estimation accuracy, while still maintaining the high throughput of the less accurate sampling methods.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=977483\">Alexandra Poulos<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3939629011957553511\">Clemson University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg123\"><span style=\"display: none;\"><!-- cal-file sess289--spostg123.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg123\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

It is challenging for HPC administrators to describe the current structure of their filesystems, predict how they will change over time, and the requirements for future filesystems as they continue to evolve. Previous studies of filesystem characteristics largely predate the modern HPC filesystems of the last decade. The Grand Unified File Index (GUFI) was used to collect the data used to compute the characteristics of six HPC filesystems indexes from Los Alamos National Laboratory (LANL) representing 2.8 PB of data, containing 36 million directories and 600 million files. We present a methodology using GUFI to characterize the shape of HPC filesystems to help system administrators to understand their key characteristics.<br><br>This document has been approved for public release under LA-UR-23-28958.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=056804\">Jenna Kline<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10021661968178810650\">Ohio State University<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3318252299045953268\">Los Alamos National Laboratory (LANL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg101\"><span style=\"display: none;\"><!-- cal-file sess289--spostg101.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg101\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This project captured the external network traffic to and from a Cray EX40 cluster over three months and analyzed it utilizing two open-source intrusion detection tools, Suricata and Zeek. The tool alerts were sent to Splunk via rsyslog for parsing and analysis. Several security concerns were identified, including excessive failed authentication attempts and the use of four invalid certificates. Multiple cluster configuration issues were also identified, including recurrent anomalous Domain Name Service (DNS) queries which comprised 97% of all DNS traffic and incorrectly routed outbound Hypertext Transfer Protocol traffic. The port mirror architecture combined with network intrusion detection tools offered valuable insight into security concerns and several configuration issues. Excessive failed authentication attempts and a switch DNS configuration issue were both resolved by this project.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=054804\">Daniel Wild<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3318252299045953268\">Los Alamos National Laboratory (LANL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=17434243736301144675\">University of New Mexico<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg103\"><span style=\"display: none;\"><!-- cal-file sess289--spostg103.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg103\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Additionally, going into the exascale era of computing, SDC error rates are only increasing with growing system sizes. State of the art methods based on instruction duplication suffer from only partial error coverage, significant synchronization overhead and strong coupling of computation and validation.<br><br>This work proposes a novel communication-avoiding approach of detecting and mitigating SDCs at the job level within the workload manager, assuming a directed acyclic graph (DAG) job model. Each job only communicates a locally generated output data hash. Computation and validation are decoupled as separately schedulable jobs and dependency stalling is avoided with a special error recovery method. The implementation of this project within the SLURM workload manager is in progress and key design aspects are outlined.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=644804\">Laslo Hunhold<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10028829971824515934\">University of Cologne<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg104\"><span style=\"display: none;\"><!-- cal-file sess289--spostg104.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg104\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

To leverage the exaflops of GPUs from Frontier (AMD) and Aurora (Intel), users of high performance computing (HPC) legacy codes originally written to target NVIDIA GPUs will have to make decisions with implications regarding porting effort, performance, and code maintainability. To facilitate HPC users navigating this space, we have established a pipeline that combines generalized GPU performance models with proxy applications to evaluate the performance portability of a massively parallel computational fluid dynamics (CFD) code in CUDA, SYCL, HIP, and Kokkos with backends on current NVIDIA-based machines as well as testbeds for Aurora (Intel) and Frontier (AMD). We demonstrate the utility of predictive models and proxy applications in gauging performance bounds and guiding hand-tuning efforts.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=093304\">Aristotle Martin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11350818937430738967\">Duke University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess289\" ssid=\"spostg106\"><span style=\"display: none;\"><!-- cal-file sess289--spostg106.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess289--spostg106\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Implemented in C++ and Thrust, it is a highly performant and portable code. Here we focus on different algorithmic formulations for calculating cumulative values like infectiousness at different locations. A detailed comparison of time and efficiency on different CPUs and GPUs was conducted, revealing suboptimal parallel efficiency. The time to execute 704 simulations on each platform was evaluated, emphasizing overall throughput instead of latency for more taxing workloads. We benchmarked modern CPU and GPU architectures, revealing the superior performance of NVIDIA A100 and AMD Genoa-X platforms.  Additionally, the monetary cost associated with executing the simulations was analyzed, presenting a contrasting landscape in on-demand and spot pricing. Ampere Altra platform emerged as the most cost-effective. The findings contribute to understanding the efficiency, time, and cost dynamics in modeling and provide insights for the practice of pandemic response planning.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=258273\">Istvan Z.

Most existing supernovae simulation codes are only designed to run on homogeneous CPU-only systems and do not take advantage of the increasing shift towards heterogeneous architectures in HPC. To address this, we present Ares, the first performance portable massively-parallel code for simulating thermonuclear burn fronts. By creating multi-physics modules using the Kokkos and Parthenon frameworks, we are able to scale supernovae simulations to distributed HPC clusters operating on any of CUDA, HIP, SYCL, HPX, OpenMP and serial backends. We evaluate our application by conducting weak and strong scaling studies on both CPU and GPU clusters, showing the efficiency of our method for a diverse set of targets.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=061204\">Landon Dyken<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1532017864130644666\">University of Illinois, Chicago<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=739804\">Alexander Holas<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9961553505116807751\">Heidelberg Institute of Theoretical Studies<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=439804\">Mark Ivan Ugalino<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=839804\">Md Nageeb Bin Zaman<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3723877145212338913\">Louisiana State University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost180\"><span style=\"display: none;\"><!-- cal-file sess291--rpost180.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost180\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Tensor parallelism, while capable of optimizing latency, entails a substantial expenditure. Conversely, pipeline parallelism excels in throughput but falls short in minimizing execution time.<br><br>To address this challenge, we introduce a novel solution - interleaved parallelism. This approach interleaves computation and communication across requests. Our proposed runtime system harnesses GPU scheduling techniques to facilitate the overlapping of communication and computation kernels, thereby enabling this pioneering parallelism for distributed large model inference. Extensive evaluations show that our proposal outperforms existing parallelism approaches across models and devices, presenting the best latency and throughput in most cases.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=712383\">Jiangsu Du<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=510904\">Jinhui Wei<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=581793\">Jiazhi Jiang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=676893\">Shenggan Cheng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13029754924601781751\">National University of Singapore<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=107493\">Zhiguang Chen<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_845983.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_845983.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=845983\">Dan Huang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=634493\">Yutong Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15821492987135649040\">Sun Yat-sen University, Guangzhou<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost196\"><span style=\"display: none;\"><!-- cal-file sess291--rpost196.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost196\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, its utility in studying high Reynolds number (Re) wall turbulence of particular interest is limited by the rapidly growing grid size (i.e., the memory and computation requirement) with Re^3. <br><br>We present PowerLLEL, a high-performance finite difference solver tailored for the challenging DNS of incompressible wall turbulence at extreme scales. An adaptive multi-level parallelization strategy is proposed to fully exploit the multi-level parallelism of various architectures and enhance computational performance. The communication performance of global transpose and halo exchange is significantly improved by a tridiagonal solver based on the parallel diagonal dominant (PDD) algorithm and three RDMA-implemented communication optimizations.  Strong scaling tests on the Tianhe-2A supercomputer show that PowerLLEL achieves nearly 92% parallel efficiency with up to 31,104 cores on a grid size of 143.3 billion.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=297804\">Jiabin Xie<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13407680677364401178\">Sun Yat-sen University, Guangzhou, China<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=925704\">Guangnan Feng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13407680677364401178\">Sun Yat-sen University, Guangzhou, China<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=256004\">Han Huang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13407680677364401178\">Sun Yat-sen University, Guangzhou, China<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=160904\">Junxuan Feng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13407680677364401178\">Sun Yat-sen University, Guangzhou, China<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=332173\">Yutong Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13407680677364401178\">Sun Yat-sen University, Guangzhou, China<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost224\"><span style=\"display: none;\"><!-- cal-file sess291--rpost224.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost224\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, much of the effort around FEM on GPU\u2019s has been focused on high order discretizations due to their higher arithmetic intensity and order of accuracy. For applications such as the simulation of geologic reservoirs, high levels of heterogeneity results in high-resolution grids characterized by highly discontinuous (cell-wise) material property fields. Additionally, the significant uncertainties typical of geologic reservoirs reduces the benefits of high order accuracy, and low order methods are typically employed. In this study, we present a strategy for implementing highly performant low-order matrix-free FEM operator kernels in the context of the conjugate gradient method. Performance results of the operator kernel are presented and are shown to compare favorably to matrix-based SpMV operators on V100, A100, and MI250X GPUs.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=150983\">Randolph Settgast<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=526504\">William Tobin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=050983\">Nicola Castelletto<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=965583\">Yohann Dudouit<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=1719361645118200089\">Sergey Klevtsov<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13154651856843062965\">Stanford University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=326504\">Ben Corbett<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost226\"><span style=\"display: none;\"><!-- cal-file sess291--rpost226.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost226\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Our RTM implementation processes three-dimensional fields on multiple NVIDIA GPUs using the Revolve algorithm for checkpointing. However, transferring data between the host and GPU memory introduces a bottleneck.<br><br>We introduced a checkpoint prefetching mechanism to overcome this, anticipating memory transfers from host to GPU. Additionally, we integrated GPU data compression using the cuZFP library to reduce data transfer sizes further. The experimental results demonstrated significant performance improvements, achieving a speedup of 1.98x - 2.53x in our benchmark dataset.

The log-likelihood function is utilized to evaluate the Gaussian model for a set of measurements in N geographical locations. Several studies have shown a utilization of modern hardware to scale the log-likelihood function for handling large numbers of locations. ExaGeoStat is an example of software that allows parallel statistical parameter estimation from the log-likelihood function. However, generating a covariance matrix is mandatory and challenging when estimating the log-likelihood function. In ExaGeoStat, the generation process was performed on CPU hardware due to missing math functions in CUDA libraries, e.g., the modified Bessel function of the second kind. This study aims to optimize the generation process using GPU with two proposed generation schemes: pure GPU and hybrid. Our implementations demonstrate up to 6X speedup with pure GPU and up to 1.5X speedup with the hybrid scheme.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=145804\">Zipei Geng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_729563.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_729563.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=729563\">Sameh Abdulah<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_059843.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_059843.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=059843\">Hatem Ltaief<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=804273\">Ying Sun<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=904273\">Marc Genton<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_495343.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_495343.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=495343\">David Keyes<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1748780573762744685\">King Abdullah University of Science and Technology (KAUST)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost140\"><span style=\"display: none;\"><!-- cal-file sess291--rpost140.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost140\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We present ParLeiden, a pioneering parallel Leiden strategy designed for distributed environments. By thread locks and efficient buffers, we effectively resolve community joining conflicts and reduce communication overheads.  We can run Leiden algorithm on large-scale graphs and achieve performance speedup on up to 9.8 times than baselines.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=835804\">Yongmin Hu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7255867677860789274\">Douyin Vision Co., Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=283383\">Jing Wang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9584610001734641406\">Shanghai Jiao Tong University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=735804\">Cheng Zhao<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7255867677860789274\">Douyin Vision Co., Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=896804\">Yibo Liu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9584610001734641406\">Shanghai Jiao Tong University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=996804\">Cheng Chen<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7255867677860789274\">Douyin Vision Co., Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=007804\">Xiaoliang Cong<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7255867677860789274\">Douyin Vision Co., Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=424563\">Chao Li<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9584610001734641406\">Shanghai Jiao Tong University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost106\"><span style=\"display: none;\"><!-- cal-file sess291--rpost106.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost106\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This method was implemented as the scalable distributed learning on Fugaku. Our method constitutes a dimensional reduction using a convolutional-autoencoder-like neural network and the time evolution prediction using long short-term memory networks. The time evolution of the turbulent three-dimensional flow (e.g., Re=2.8\u00d710^6) could be simulated at a significantly lower cost (approximately four orders of magnitude) without a major loss in accuracy. Using the single core memory group, our implementation shows 370 GFLOPS (24.28% of the peak performance) for the entire training loop and 753 GFLOPS (24.28% of the peak performance) for the convolution kernel. Our implementation scales up to 25,250 computational nodes (1,212,000 cores). Thus it shows 72.9 % of weak scaling performance (7.8 PFLOPS) for the entire training loop. On the other hand, the convolution routine shows 100.8% of weak scaling performance (113 PFLOPS).<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=611263\">Kazuto Ando<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15343858051963816011\">Kobe University, Japan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=637473\">Rahul Bale<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15343858051963816011\">Kobe University, Japan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=586753\">Akiyoshi Kuroda<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=179073\">Makoto Tsubokura<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15343858051963816011\">Kobe University, Japan<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost125\"><span style=\"display: none;\"><!-- cal-file sess291--rpost125.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost125\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Additionally, the use of complex patient-specific geometries and biophysically-detailed ionic models adds to the system's complexity. To numerically solve such problems within reasonable timeframes, high-performance computing plays a crucial role. In this poster, we present a high-performance electrophysiology library specifically designed to address these demanding simulations. The library's routines support the use of linear, and quadratic tetrahedral elements. Moreover, our library offers a two-way coupling capability that enables interactions among multi-dimensional meshes. This important feature facilitates the simulation of electrical interactions between insulated regions of the heart, such as the atria and the ventricles. By enabling such coupling, the library aims to contribute to a more comprehensive understanding of the heart's electrophysiology and its intricate electrical behavior.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=601504\">Laryssa Abdala<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14804329364160916574\">University of North Carolina<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=118804\">Simone Rossi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9225078553272591991\">Align Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=218804\">David Wells<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14804329364160916574\">University of North Carolina<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=442863\">Boyce Griffith<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=14804329364160916574\">University of North Carolina<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost164\"><span style=\"display: none;\"><!-- cal-file sess291--rpost164.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost164\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Genome Analysis ToolKit's HaplotypeCaller, relying on the Pair Hidden Markov Model (PairHMM) algorithm, is one of the most used applications to identify such variants. However, the PairHMM represents the bottleneck for this tool. Deploying such an algorithm on hardware accelerators represents a valuable solution. Nevertheless, State-of-the-Art designs do not have the flexibility to support the length variability of the input sequences and are not usable in real-life applicative scenarios. For these reasons, this work presents a GPU accelerator for the PairHMM capable of supporting sequences of any length, thanks to a dynamic memory swap methodology, overcoming the limitation of literature solutions. Our accelerator achieves an 8154\u00d7 speedup over the software baseline, surpassing the most-performant State-of-the-Art design up to 1.6\u00d7.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=127804\">Beatrice Branchini<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=218193\">Alberto Zeni<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=090563\">Marco Santambrogio<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost179\"><span style=\"display: none;\"><!-- cal-file sess291--rpost179.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost179\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The problem is further complicated by the sheer size of the human genome, roughly three billion base pairs long. Therefore, computation is time-consuming and data-intensive. To solve this problem for human colorectal cancer, we are implementing a machine learning engine based on inverse reinforcement learning, and includes several different kinds of neural networks to perform data preparation, training, and prediction. Our work aims to reconstruct the progression of tumor development in a sample, and predict the next steps of its evolution, to aid in diagnosis and treatment. This poster will be presented as a work in progress methodology.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=374104\">Silba Dowell<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=989804\">Daniel Hintz<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=099804\">Tyson Limato<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=199804\">Shad Sellers<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=299804\">Milana Wolff<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=518904\">Nicholas Chia<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=433204\">Liudmila Mainzer<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15714301261647032250\">University of Wyoming<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost186\"><span style=\"display: none;\"><!-- cal-file sess291--rpost186.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost186\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

It has been a challenging problem historically, owing to the irregular and dynamic nature of the algorithm, which not only inhibits compile-time optimizations, but also requires runtime optimizations such as message aggregation and load-imbalance mitigation. Popular triangle counting algorithms are either inherently slow, fail to take advantage of available vectorization in modern processors, or involve sparse matrix operations. With its support for fine-grained asynchronous messages, the Partitioned Global Address Space (PGAS) with the Actor model has been identified to be efficient for irregular applications. However, few triangle counting implementations have been optimally implemented on top of PGAS Actor runtimes. To address the above mentioned challenges, we propose a set-intersection-based implementation of a distributed triangle counting algorithm atop the PGAS Actor runtime. Evaluation of our approach on the PACE Phoenix cluster and the Perlmutter supercomputer shows encouraging results.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=831504\">Aniruddha Mysore<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=228804\">Kaushik Ravichandran<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=068404\">Youssef Elmougy<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=349953\">Akihiro Hayashi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_299473.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_299473.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=299473\">Vivek Sarkar<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12939568275105511326\">Georgia Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost187\"><span style=\"display: none;\"><!-- cal-file sess291--rpost187.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost187\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This work addresses the computational cost of estimating K-path centrality in large-scale graphs by introducing the random neighbor traversal graph (RaNT-Graph). The distributed graph data structure employs a combination of vertex delegation partitioning and rejection sampling, enabling it to sample massive amounts of random paths on large scale-free graphs. We evaluate our approach by running experiments which demonstrate strong scaling on large real-world graphs. The RaNT-Graph approach achieved a 56,544x speedup over the baseline 1D partition implementation when estimating K-path centrality on a graph with 89 million vertices and 1.9 billion edges.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=355104\">Lance Fletcher<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1915623848265844395\">Texas A&M University<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=737393\">Trevor Steil<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=788904\">Roger Pearce<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1915623848265844395\">Texas A&M University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost188\"><span style=\"display: none;\"><!-- cal-file sess291--rpost188.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost188\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

In this work, we provide a brief overview of NWQ-Sim and its implementation in simulating quantum circuit applications, such as the transverse field Ising model. We also demonstrate how NWQ-Sim can be used to examine the effects of errors that occur on real quantum devices, using a combined device noise model. Moreover, NWQ-Sim is particularly well-suited for implementing variational quantum algorithms where circuits are dynamically generated. Therefore, we also illustrate this with the variational quantum eigensolver (VQE) for the Ising model. In both cases, NWQ-Sim's performance is comparable to or better than alternative simulators. We conclude that NWQ-Sim is a useful and flexible tool for simulating quantum circuits and algorithms, with performance advantages and noise-aware simulation capabilities.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=446204\">In-Saeng Suh<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16969005850305409037\">Oak Ridge National Laboratory (ORNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=472563\">Ang Li<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost195\"><span style=\"display: none;\"><!-- cal-file sess291--rpost195.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost195\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

LDU-factorization with pivoting strategy provides robust solver for such system. Computational complexity of the factorization solver is high and cannot be reduced in framework of the direct solver, but by using lower precision arithmetic, computational cost and memory usage could be reduced. LDU-factorization uses recursive generation of the Schur complement matrix, but generation of the last one can be replaced by an iterative method. Here decomposition of the whole matrix into a union of the moderate and hard parts during factorization with threshold pivoting plays a key role. A new algorithm uses factorization in lower precision as a preconditioner for iterative solver in higher precision to generate the last Schur complement. True mixed precision arithmetic is used in forward\/backward substitution for preconditioner with factorized matrix in lower precision and RHS vectors in higher.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=810904\">Atsushi Suzuki<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost212\"><span style=\"display: none;\"><!-- cal-file sess291--rpost212.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost212\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

For instance, PR-DNS may complement experimental facilities designed to study key physical processes in a controlled environment and therefore serve as digital twins for such cloud chambers. In this poster we present our ongoing work aimed at enabling the use of a PR-DNS model for this purpose. We consider two approaches: traditional HPC techniques and emerging machine learning methods.

class=\"info-label\"><span class=\"default-text\">Description<\/span><\/span><span class=\"abstract\">Collective I\/Os are widely used to transform small non-contiguous accesses into large contiguous accesses for parallel I\/O optimization. The existing collective I\/O techniques assume that computer memory is volatile. They are limited both by the size of the buffer, which must be small so data is not lost during a crash, and the communication overhead that occurs during collective I\/O. PMIO is a proposed framework to utilize persistent memory (PMEM) for collective I\/O, as opposed to DRAM. First, we utilize a log-structured buffer to take advantage of the non-volatility of PMEM. Second, we utilize larger buffers to take advantage of the larger space available on less expensive PMEM. Finally, we implement a two-phase merging algorithm to eliminate the communication overhead. The poster provides an overview of collective I\/O and its problems, an introduction to PMEM, an outline of PMIO, and a brief discussion of PMIO's performance.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=652893\">Keegan Sanchez<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=17932552841970429427\">Washington State University, Vancouver<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=174693\">Alex Gavin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=17932552841970429427\">Washington State University, Vancouver<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_509253.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_509253.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=509253\">Suren Byna<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10021661968178810650\">Ohio State University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_086253.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_086253.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=086253\">Kesheng Wu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_114853.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_114853.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=114853\">Xuechen Zhang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=17932552841970429427\">Washington State University, Vancouver<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess307\" ssid=\"rpost148\"><span style=\"display: none;\"><!-- cal-file sess291--rpost148.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost148\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

NVMe-over-Fabrics (NVMe-oF) is the standardized protocol used for accessing disaggregated storage over the network. Currently, the NVMe-oF specification lacks any semantics to prioritize I\/O requests based on different application needs. Since applications have varying goals \u2014 latency-sensitive or throughput-critical I\/O \u2014 we need to design efficient schemes in order to allow applications to specify the type of performance they wish to achieve. Furthermore, with additional tenants, we need to provide the respective specified performance optimizations that each application requests, regardless of congestion. This is a challenging problem, as the current NVMe specification lacks semantics to support multi-tenancy. Our research poster brings awareness to the ways in which we can bring multi-tenancy support to the NVMe-oF specification.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=048504\">Darren Ng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=544993\">Charles Parkinson<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=748504\">Andrew Lin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=125393\">Arjun Kashyap<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_625953.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_625953.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=625953\">Xiaoyi Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost171\"><span style=\"display: none;\"><!-- cal-file sess291--rpost171.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost171\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Therefore, it is critical to understand data flow. Many scientific datasets incorporate domain semantics with formats like HDF and NetCDF, enhancing the interpretability and context of the data for analysis. We shed new insights on workflow bottlenecks by understanding how semantic data sets flow through storage. We unveil a fresh perspective with careful runtime measurement, recovering the mapping of domain semantics to low-level I\/O operations, and effective visualization and analysis of semantic flows.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_961693.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_961693.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=961693\">Meng Tang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_053843.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_053843.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=053843\">Nathan R.

We have developed a streaming graph framework which, while ingesting an unbounded stream of events mirroring a graph's evolution, dynamically updates the solution to a user query, and is able to offer, on-demand and with low latency, the solution to the query. Integral to our framework is that graph topology changes and algorithmic messages are processed concurrently, asynchronously, and autonomously (i.e., without shared state). This poster uses graph coloring as a challenge problem to highlight two advantages of our framework beyond those showcased by past work (i.e., low result latency, high sustained ingestion throughput, and scalability). These additional advantages are: (i) the ability to efficiently leverage the \"free\" computational resources available when the rate of incoming topology events is below the maximum sustainable throughput, and (ii) the ability to produce \"stable\" solutions to queries as the graph evolves.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=244804\">Juntong Luo<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6484252329791759635\">University of British Columbia<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=535363\">Scott Sallinen<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6484252329791759635\">University of British Columbia<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=692443\">Matei Ripeanu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6484252329791759635\">University of British Columbia<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost161\"><span style=\"display: none;\"><!-- cal-file sess291--rpost161.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost161\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

In order to use HPC systems efficiently, one has to be aware of their architectural details, in particular details of their hardware topology, which is increasingly affected by dynamic runtime settings.<br><br>sys-sage is a novel approach providing an infrastructure for storage, correlation, and provision of HW-related system information. It uses information from various well-known sources as well as use-case-specific solutions, and correlates the particular pieces together to provide a full view of a system. The novelty of our approach lies in the ability to capture dynamic environments as well as systems\u2019 complexities, and in enabling greater flexibility in its usage.<br><br>sys-sage is publicly available and can be used by many applications. It integrates widely used approaches, such as hwloc or dynamic counter information, and offers user-integration of all other user-specific data sources.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=753304\">Stepan Vanecek<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7785079229514551539\">Technical University of Munich<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_796343.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_796343.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=796343\">Martin Schulz<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7785079229514551539\">Technical University of Munich<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost114\"><span style=\"display: none;\"><!-- cal-file sess291--rpost114.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost114\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

For such applications, the communication pattern comprises of variable-sized data exchanges between process neighbors in a process graph topology, which unlike process grid for rectangular problems is difficult to optimize for enhancing the locality in a sustainable fashion.<br><br>Process assignment or remapping can improve the communication performance, however, existing solutions mostly caters to Cartesian process topologies and not the graph topology. In this work, we propose application and topology agnostic process remapping strategies for graph applications. For two communication intensive distributed-memory graph applications (graph clustering and triangle counting), we demonstrate about 30% improvements in the overall execution times through various remapping methodologies via SST-based packet-level simulations on Dragonfly and Fat Tree based network topologies.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=800093\">Md Nahid Newaz<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11386228025488668598\">Oakland University<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=908773\">Sayan Ghosh<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=068863\">Joshua Suetterlein<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_053843.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_053843.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=053843\">Nathan Tallent<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=920904\">Hua Ming<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11386228025488668598\">Oakland University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost170\"><span style=\"display: none;\"><!-- cal-file sess291--rpost170.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost170\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Existing work in literature has explored DPUs in the context of machine learning, compression and MPI acceleration. We show our designs on how to integrate DPUs into existing high performance geospatial systems like MPI-GIS. The workflow of a typical spatial computing workload consists of two phases - filter and refine. First we used DPU as a target to offload spatial computations from the host CPU. We show the performance improvements due to offload. Next we used DPU for network I\/O processing. In network I\/O case, the query data first comes to DPU for filtering and then the query goes to CPU for refinement. DPU-based filter and refine system can be useful in other domains like Physics where an FPGA is used to perform the filter to handle Big Data.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=078804\">Derda Kaymak<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1411530722621345050\">Marquette University<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=637904\">Satish Puri<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6807234110099488634\">Missouri University of Science and Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost176\"><span style=\"display: none;\"><!-- cal-file sess291--rpost176.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost176\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Data compression can decrease the volume of data we need to move and store. TEZIP is a neural network (NN) based compressor designed for high-quality compression of time-evolving data. However, TEZIP is written in Python and is not easily usable from or ported to C++. In this work, we develop new components in LibPressio that allow us to integrate with TEZIP and other external compressors efficiently and evaluate them with a systematic approach. We find that TEZIP\u2019s compression ratio (Error Bound 1e-06) for Hurricane Isabel is 128, which is 2.4 times greater than the leading SZ3\u2019s, 52.8. Our basic integration of TEZIP into Libpressio sets a precedent for the integration of non C\/C++ compressors into LibPressio.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=175804\">Isita Talukdar<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=18148127394821532612\">University of California, Berkeley<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=408904\">Amarjit Singh<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=634273\">Robert Underwood<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_066453.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_066453.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=066453\">Kento Sato<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1686566454178910924\">RIKEN Center for Computational Science (R-CCS)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=893763\">Weikuan Yu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2064839953530329817\">Florida State University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost124\"><span style=\"display: none;\"><!-- cal-file sess291--rpost124.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost124\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This requires the Monte Carlo simulation to be updated periodically to quantify potential changes and improvements in science results with more detailed modelling of the systematic effects. IceCube\u2019s largest systematic effect comes from the optical properties of the ice the detector is embedded in. Over the last few years there have been considerable improvements in the understanding of the ice, which require a significant processing campaign to update the simulation. In winter 2023, the NRP project offered to provide the needed GPU compute to IceCube in support of this activity. Given the mostly uniform nature of such a simulation campaign, we thus have enough statistics to properly characterize the relative performance of the dozen GPU models present in the NRP in the context of IceCube.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=147883\">David Schultz<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8280757605430798435\">University of Wisconsin, Madison<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_798383.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_798383.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=798383\">Igor Sfiligoi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3918581092836434221\">University of California, San Diego (UCSD)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=240204\">Benedikt Riedel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8280757605430798435\">University of Wisconsin, Madison<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=227573\">Frank W\u00fcrthwein<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3918581092836434221\">University of California, San Diego (UCSD)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost143\"><span style=\"display: none;\"><!-- cal-file sess291--rpost143.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost143\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Current HPC systems over-provision compute and memory resources to meet requirements of diverse workloads. In this work, we explore using network-attached memory for disaggregating memory from compute nodes to satisfy the demand of memory-intensive workloads. We provide a library that enables applications to access network-attached memory as if in its main memory, and exposes critical controls to userspace, including concurrency level and page-level data compression. Our preliminary results show that the flexibility of tuning concurrency and compression is important for improving performance and reducing data movement. Also, our results on 12 scientific data sets indicate that DPU compression offloading could significantly speed up compression and is important for future optimizations.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_103993.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_103993.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=103993\">Jacob Wahlgren<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=307804\">Jennifer Faj<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=860683\">Eric Green<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_442643.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_442643.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=442643\">Maya Gokhale<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_072673.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_072673.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=072673\">Ivy Peng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost154\"><span style=\"display: none;\"><!-- cal-file sess291--rpost154.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost154\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Within these workflows, tasks often produce intermediate results that may serve as inputs to subsequent tasks within the workflow. These results can vary in size and may need to be transported to another worker node. Data movement can become the primary bottleneck for many scientific workflows thus minimizing the cost of data movement can provide a significant performance benefit for a given workflow. Distant futures enable transfers between worker nodes, eliminating the need for intermediate results to pass through a centralized manager for future tasks invocations. Additionally, asynchronous transfers enable increased concurrency by preventing the blocking of task invocations. This poster shows the performance benefit received from the implementation of distant futures within a workflow that produces numerous intermediate results.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=233793\">Barry Sly-Delgado<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10028771542868992611\">University of Notre Dame<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=696253\">Douglas Thain<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10028771542868992611\">University of Notre Dame<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost157\"><span style=\"display: none;\"><!-- cal-file sess291--rpost157.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost157\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none; color: #bbbbbb; width: 30px;\" tabindex=\"0\" title=\"add to My Schedule\" value=\"add\"><img decoding=\"async\" alt=\"add to My Schedule\" class=\"ll-icon\" src=\"https:\/\/submissions.supercomputing.org\/static_resources\/icon_plus_gray.png\" \/><\/span><span class=\"agenda-button agenda-remove-button clickable\" name=\"remove_from_agenda\" role=\"switch\" style=\"display: none; color: black; width: 30px;\" tabindex=\"0\" title=\"remove from My Schedule\" value=\"remove\"><img decoding=\"async\" alt=\"remove from My Schedule\" class=\"ll-icon\" src=\"https:\/\/submissions.supercomputing.org\/static_resources\/icon_minus_green.png\" \/><\/span><\/span><\/div><div class=\"info-section room-sect\"><span class=\"info-label\"><span class=\"default-text\">Location<\/span><\/span><span class=\"room\"><a href=\"\/map\/?location=rDEF-Concourse\">DEF Concourse<\/a><\/span><\/div><div class=\"info-section presentation-track-sect registration-category tag_group104\"><span class=\"hide-small info-label\"><span class=\"default-text\">Registration Categories<\/span><\/span><span class=\"presentation-tracks\"><div class=\"ptrack-list\"><div class=\"registration-category tag-group-list tag_group104\"><div class=\"program-track ptrack165-snippet\" style=\"display: inline-block;\"><div class=\"tech-program-registration\" style=\"\ndisplay: inline-block; \nbackground-color: #2772E5;\nfont-size: 12px;\ncolor: white;\npadding: 3px;\n\" title=\"Tech Program Reg Pass\">\nTP\n<\/div><\/div><div class=\"program-track ptrack168-snippet\" style=\"display: inline-block;\"><div class=\"tech-program-registration\" style=\"\ndisplay: inline-block; \nbackground-color: #2772E5;\nfont-size: 12px;\ncolor: white;\npadding: 3px;\n\" title=\"Tech Program Reg Pass\">\nXO\/EX\n<\/div><\/div><\/div><\/div><\/span><\/div><div class=\"info-section archive-link\">\n    <span class=\"info-label\">\n        <span class=\"default-text\">Archive<\/span>\n    <\/span> \n    <a href=\"https:\/\/sc23.supercomputing.org\/proceedings\/tech_poster\/tech_poster_pages\/rpost157.html\" target=\"_blank\">view<\/a>\n<\/div><div class=\"info-section next-presentation-sect\"><span class=\"info-label\"><span class=\"default-text\">Next Presentation<\/span><\/span><a href=\"\/presentation\/?id=rpost211&sess=sess291\">Next Presentation<\/a><div class=\"ll_countdown\" hide_when_done=\"1\" reload=\"0\" show_seconds=\"0\" target_dt=\"2023-11-14T10:00:00-0700\" target_url=\"\/presentation\/?id=rpost211&sess=sess291\"><\/div><a href=\"\/presentation\/?id=rpost211&sess=sess291\">Why Wait!?

Analyzing these large files often results in inefficiency due to I\/O stalls. To mitigate these stalls, certain data can be pre-computed during the production phase and queried during analysis. However, this solution demands added storage capacity and an astute use of storage hierarchies. In this context, we introduce Hades, an I\/O engine seamlessly integrated with the Adios2 framework. Hades offers hierarchical buffering, which enables smart data placement and prefetching across the spectrum of I\/O devices. Additionally, it is adept at computing basic derived quantities required by I\/O applications, such as the global and local min\/max values. A notable feature of Hades is its memory-first metadata management strategy, which is designed for querying derived data, significantly enhancing system performance.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=625583\">Jaime Cernuda<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=650783\">Luke Logan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_220663.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_220663.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=220663\">Anthony Kougkas<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=6019430249947364998\">Xian-He Sum<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost211\"><span style=\"display: none;\"><!-- cal-file sess291--rpost211.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost211\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

While SHA256 has been widely used in many blockchain implementations, its throughput and efficiency has led the rise of a modern lightweight and speed superior implementation BLAKE3. We compared and contrasted SHA256 and BLAKE3 with a focus on blockchain workloads with small inputs and outputs. We explored different compilers and optimizations, different ways to parallelize using multi-threading and multi-processing, as well as different size systems from small Raspberry Pi 4 to a modern AMD Epyc server. We found that BLAKE3 is superior from a performance perspective. To showcase its strengths, we integrated BLAKE3 into a basic Proof-of-Space implementation that used advanced data index and search, and compared our results to the Chia blockchain plotting mechanism. Our approach offers one to two orders of magnitude higher hash generation and storage rates.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div

optimizing High Performance Computing (HPC) applications. We propose HPEE (HPC Parameter Exploration on Edge), a novel approach that formulates the parameter search space problem as a pure exploration multi-armed bandit (MAB) technique. By efficiently exploring the search space using the MAB framework, we achieve significant performance improvements, while respecting the limited computational resources of edge devices. Experimental results, based on HPC application, demonstrate the effectiveness of our approach in optimizing parameter search on edge devices, offering a promising solution for enhancing HPC performance in resource-constrained environments.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=247804\">Abrar Hossain<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15316287929551788226\">University of Toledo<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=597204\">Kishwar Ahmed<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15316287929551788226\">University of Toledo<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost149\"><span style=\"display: none;\"><!-- cal-file sess291--rpost149.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost149\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The Chimbuko framework monitors large-scale workflow applications in real-time and identifies function executions which deviate from accumulated statistics (performance anomalies). Performance anomalies across runs correlate with variation in execution times of an application; quicker resolution of performance anomalies caused by hardware issues improves cluster performance. Anomalous and normal executions are stored as events in Chimbuko. In this study, we investigate the applicability of graph-based deep learning methods for anomaly classification. We hypothesize that transforming data into a graph will allow correlations to be modeled, thus allowing graph-based methods to learn embeddings that can improve the effectiveness of downstream anomaly classification tasks. Our evaluations demonstrate that the graph-based methods yield up to 95% accuracy and outperform a state-of-the-art gradient-based method. Moreover, we provide an explanation of the classification model\u2019s decision-making process through explainable AI techniques.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_230293.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_230293.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=230293\">Chase Phelps<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16151704559435182252\">Texas State University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=102404\">Ankur Lahiry<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16151704559435182252\">Texas State University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_017573.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_017573.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=017573\">Tanzima Z.

expensive ways to allocate large amounts of memory in HPC environments. Memory pools commonly contain both allocations that persist for only a portion of the program (temporary) and those that persist for the entire program (permanent). However, too much of a mix of both allocation types can lead to pool fragmentation and cause the pool to perform poorly. Umpire created a tool that uses a machine learning model to perform temporal classifications and categorize allocations as either temporary or permanent. We conducted experiments using trace files from two LLNL applications to study how much memory can be saved when those allocations are separated into distinct pools. We found that our ML tool accurately classifies memory allocations and that separating these allocation types into distinct pools reduces overall memory usage significantly (up to 29.5%).<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=102193\">Kristi Belcher<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=803683\">David Beckingsale<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=462804\">Sam Schwartz<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2854505398367532833\">University of Oregon<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=760683\">Marty McFadden<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost139\"><span style=\"display: none;\"><!-- cal-file sess291--rpost139.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost139\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

One key limitation of such approaches is that their success depends, to a large degree, on the formulation of the outcome or objective, which is typically done by human experts. In this paper, we propose a novel approach of automatically generating new optimization heuristics using inductive program synthesis. To explore the feasibility of this approach, we investigated the graph-coloring register allocation heuristic used in the state-of-the-art compilers today. In particular, we focused on the task of live range splitting. The results show that when using a Genetic Algorithm, we can obtain splitting heuristics that are within 10% of the optimal split after 202 generations.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=823404\">Mohammad Ali<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16151704559435182252\">Texas State University<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_905063.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_905063.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=905063\">Apan Qasem<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16151704559435182252\">Texas State University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost193\"><span style=\"display: none;\"><!-- cal-file sess291--rpost193.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost193\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

To tackle this challenge, we propose a novel neural domain decomposition algorithm to accelerate its solution. Our approach hinges on two key ideas: first, using neural PDE solvers to approximate the solutions within subdomains, and second, ensuring continuity across subdomain boundaries by solving a Schur complement system derived from the cell-centered discretized Poisson equation. A distinct advantage of our approach lies in generating a large dataset consisting only of small-scale problems to train the subdomain solver. This trained model can subsequently be applied to problems with large and complex geometries. Moreover, by batching the independent subdomain solves, we achieve high GPU utilization with neural solvers compared to state-of-the-art numerical methods. In contrast to neural domain decomposition algorithms that rely on Schwarz overlapping methods, our optimization-based approach, coupled with neural PDE solvers, improves accuracy and performance.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=205104\">Sebastian Barschkis<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16551851980234357854\">University of California, Irvine<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=888504\">Zitong Li<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16551851980234357854\">University of California, Irvine<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=989773\">Hengjie Wang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=7194033812574329752\">Modular Inc<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_005663.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_005663.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=005663\">Aparna Chandramowlishwaran<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16551851980234357854\">University of California, Irvine<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost200\"><span style=\"display: none;\"><!-- cal-file sess291--rpost200.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost200\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Our original application is a computational stratigraphy codebase that couples fluid flow and sediment deposition submodels. The application uses domain decomposition and a halo exchange to split the workload among multiple workers in a distributed system. Our methodology abstracts and conserves the host data structures while re-writing computational elements in the GPU programming language CUDA. Utilizing high performance GPU machines in the Azure cloud, we show a minimum 90x speedup compared to a high-end CPU based cluster. In this poster, we give a brief description of the original algorithm, followed by a discussion of required software changes and additions. Although this case study focuses on a specific example, we hope this approach inspires similar efforts in other applications.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=934804\">Martin Kuhnel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5176934492498828554\">Chevron<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=679963\">Alex Loddoch<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5176934492498828554\">Chevron<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=227804\">Tao Sun<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5176934492498828554\">Chevron<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost130\"><span style=\"display: none;\"><!-- cal-file sess291--rpost130.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost130\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Traditionally, delivering HPC System Administrator training has been through physical face-to-face workshops, using cloud-based services or remote hardware to provide compute resources to emulate an HPC system. There are several challenges associated with this approach, including class size limits, available compute resources, and disrupting work hours to attend training. By following lessons learned from MOOC methodology on developing HPC Training we have produced a reproducible, accessible, self-paced HPC virtual training lab that emulates a basic 3-node compute cluster on a trainee\u2019s local machine without the need for any high-end computing resources or cloud infrastructure.<br><br>Our poster will provide an overview of the project, inter alia the delivery platforms, components and features of the lab, lessons learned and future improvements, as well as future plans for extended HPC training modules following this delivery format.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_453973.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_453973.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=453973\">Bryan Johnston<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15948089189160965873\">Council for Scientific and Industrial Research (CSIR), South Africa<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12805122936318586264\">Center for High Performance Computing (CHPC), South Africa<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_397804.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_397804.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=397804\">Lara Timm<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15948089189160965873\">Council for Scientific and Industrial Research (CSIR), South Africa<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12805122936318586264\">Center for High Performance Computing (CHPC), South Africa<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_507904.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_507904.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=507904\">Mabatho Hashatsi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=15948089189160965873\">Council for Scientific and Industrial Research (CSIR), South Africa<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=12805122936318586264\">Center for High Performance Computing (CHPC), South Africa<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost150\"><span style=\"display: none;\"><!-- cal-file sess291--rpost150.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost150\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

EE-HPC achieves a more efficient energy use of HPC systems by targeted job-specific control and optimization of the hardware. The project started end of 2022 and builds on the existing stable software components ClusterCockpit and LIKWID. It provides a simple, robust, secure and scalable monitoring and energy control solution for hybrid HPC clusters. The job-specific performance and monitoring framework ClusterCockpit is already used in production at several large HPC computing centers. The energy manager and node controller is implemented in a Python based prototype and will be ported to Golang and integrated in ClusterCockpit. The framework will be evaluated with a set of relevant HPC applications from molecular dynamics, engineering, and climate research.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=289653\">Jan Eitzinger<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10084620596260895829\">Friedrich-Alexander University, Erlangen-Nuremberg<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13994679892764266933\">Erlangen National High Performance Computing Center<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_048604.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_048604.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=048604\">Thomas Gruber<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10084620596260895829\">Friedrich-Alexander University, Erlangen-Nuremberg<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13994679892764266933\">Erlangen National High Performance Computing Center<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost151\"><span style=\"display: none;\"><!-- cal-file sess291--rpost151.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost151\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Deep learning approaches are being developed to detect these events within streaming data but can take significant resources on large datasets (PB+). To address these limitations, we propose a solution based on streaming manifold learning, specifically the Kernel CUSUM (KCUSUM) algorithm. By leveraging KCUSUM, we can overcome the limitations of uniform sampling in MD simulations, as it compares incoming data with samples from a reference distribution. It utilizes a statistic derived from the Maximum Mean Discrepancy (MMD) non-parametric testing framework. This algorithm has been tested in various use cases, demonstrating its ability to significantly reduce data rates without missing important scientific events.<\/span><\/div><div class=\"info-section

models offline using fixed datasets, while inference serving systems (consumers) load the trained models for offering real-time inference queries. In practice, AI applications often operate in a dynamic environment where data is constantly changing. Compared to offline learning, Continuous learning frequently (re)-trains models to adapt to the ever-changing data. This demands regular deployment of the DNN models, increasing the model update frequency between producers and consumers. Typically, producers and consumers are connected via model repositories like PFS, which may result in high model update latency due to I\/O bottleneck of PFS. To address this, our work introduces a high-performance I\/O framework that speeds up model updates between producers and consumers. It employs a cache-aware model handler to minimize the latency and an intelligent performance predictor to maintain a balance between training and inference performance.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=722293\">Jie Ye<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=625583\">Jaime Cernuda<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_398263.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_398263.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=398263\">Bogdan Nicolae<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_220663.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_220663.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=220663\">Anthony Kougkas<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_472143.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_472143.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=472143\">Xian-He Sun<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost208\"><span style=\"display: none;\"><!-- cal-file sess291--rpost208.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost208\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Generating these ensembles demands significant computational resources and time, which can be crucial for risk assessments and decision-making. This study utilizes generative adversarial networks (GANs) and deep diffusion models (DDMs) to produce low-resolution ensemble runs trained on data provided by climate model simulations with low computational expense. Additionally, convolutional neural networks (CNNs) are employed for downscaling as well as parallelization techniques to enhance performance and reduce computation time. This approach allows for time-efficient exploration of high-resolution ensemble members, facilitating climate modeling investigations that were previously challenging due to resource constraints.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=357104\">Johannes Meuer<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5122291885562619455\">German Climate Computing Centre (DKRZ)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=510204\">Christopher Kadow<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5122291885562619455\">German Climate Computing Centre (DKRZ)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_814453.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_814453.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=814453\">Thomas Ludwig<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5122291885562619455\">German Climate Computing Centre (DKRZ)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=728904\">Claudia Timmreck<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5364885102115968112\">Max Planck Institute for Meteorology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost105\"><span style=\"display: none;\"><!-- cal-file sess291--rpost105.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost105\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

To promote the widespread adoption of this approach for community-based uELM development, this poster presents a portable software environment that enables efficient development of the uELM code on GPUs. The standalone software environment, which utilizes Docker, contains all the necessary code, libraries, and system software required for uELM development using SPEL. The process involved in this study includes identifying a Docker image that supports GPU, configuring and simulating ELM at the site level, capturing reference solutions, testing uELM functional units, and generating and optimizing code that is compatible with GPUs. The effectiveness of this methodology is demonstrated through a case study.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=246804\">Franklin Eaglebarger<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9597681257017929118\">Pellissippi State Community College<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=757053\">Dali Wang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16969005850305409037\">Oak Ridge National Laboratory (ORNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost118\"><span style=\"display: none;\"><!-- cal-file sess291--rpost118.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost118\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Despite their proficiency, the inconsistency in input data distributions can compromise prediction reliability. This study mitigates this issue by introducing uncertainty evaluations in DL models, thereby enhancing dependability through a distribution of predictions. Our focus lies on the Vision Transformer (ViT), a DL model that harmonizes both local and global behavior. We conduct extensive experiments on the ImageNet-1K dataset, a vast resource with over a million images across 1,000 categories. ViTs, while competitive, are vulnerable to adversarial attacks, making uncertainty estimation crucial for robust predictions.<br><br>Our research advances the field by integrating uncertainty evaluations into ViTs, comparing two significant uncertainty estimation methodologies, and expediting uncertainty computations on high-performance computing (HPC) architectures, such as the Cerebras CS-2, SambaNova DataScale, and the Polaris supercomputer, utilizing the MPI4PY package for efficient distributed training.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_981504.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_981504.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=981504\">Erik Pautsch<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13316190947445957962\">Loyola University, Chicago<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_399493.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_399493.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=399493\">John LI<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11152328118408272449\">University of California San Diego<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_421463.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_421463.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=421463\">Silvio Rizzi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_488404.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_488404.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=488404\">George Thiruvathukal<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13316190947445957962\">Loyola University, Chicago<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_686473.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_686473.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=686473\">Maria Pantoja<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=4558238438263071570\">California Polytechnic State University, San Luis Obispo<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost141\"><span style=\"display: none;\"><!-- cal-file sess291--rpost141.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost141\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, effective and interactive exploration of the profiles of large-scale parallel programs remains a challenge due to the high I\/O overheads of profiles and the difficulties in scaling downstream visualization tools. In this poster, we present a full-stack approach to a performance introspection framework that tackles key challenges in profiling and visualizing performance data at scale. Our novelty lies in a scalable and compact data model and a two-phase I\/O system, which instill scalability into the profiler making it low overhead-- even at high process counts (< 5%). We then build a web-based, visual-analytic dashboard with linked views. Our profiling and visualization tools are both lightweight and easy-to-use, which strikes a balance between providing sophisticated features and operating quickly and efficiently at high process counts.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=249804\">Ke Fan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1532017864130644666\">University of Illinois, Chicago<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=349804\">Sidharth Kumar<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1532017864130644666\">University of Illinois, Chicago<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess307\" ssid=\"rpost181\"><span style=\"display: none;\"><!-- cal-file sess291--rpost181.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost181\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The latest OpenSHMEM Specification v1.5 introduced the team concept and team-based collective communication that are similar to the communicator and collective communication in the Message Passing Interface (MPI) programming model. However, the typical design of OpenSHMEM collectives relies on one-sided communication such as PUT and Get to move the data, which is different from two-sided communication in MPI collectives. In this work, we compare OpenSHMEM collective designs using native one-sided communication and MPI-based two-sided communication on an HPC cluster. We characterize two aspects (i.e., synchronization and collective algorithms) that can influence the performance of these two different designs and use benchmarks to show the performance differences. Through our evaluation, we find that the MPI-based design is faster than the one-sided design at most times, while the one-sided design can perform faster in certain cases.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=789004\">Yuke Li<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_543263.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_543263.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=543263\">Yanfei Guo<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_625953.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_625953.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=625953\">Xiaoyi Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost201\"><span style=\"display: none;\"><!-- cal-file sess291--rpost201.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost201\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

These tools have the capability to assist developers with many of the difficulties that arise from the ever-growing complexity in the software stack.  As we enter the exascale era, with a diverse set of emerging hardware and programming paradigms, developing, optimizing, and maintaining parallel software is becoming burdensome for developers.  While LLM-based coding tools have been instrumental in revolutionizing software development, mainstream models are not designed, trained, or tested on High Performance Computing (HPC) problems.  We present a LLM fine-tuned on HPC data and demonstrate its effectiveness in HPC code generation, OpenMP parallelization, and performance modeling.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=878393\">Daniel Nichols<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=790553\">Aniruddha Marathe<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_447573.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_447573.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=447573\">Harshitha Menon<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_647443.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_647443.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=647443\">Todd Gamblin<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_534543.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_534543.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=534543\">Abhinav Bhatele<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost220\"><span style=\"display: none;\"><!-- cal-file sess291--rpost220.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost220\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This work provides an in-depth analysis of Vlasiator, focusing on MPI performance using the Integrated Performance Monitoring (IPM) tool. We show that MPI non-blocking point-to-point communication accounts for most of the communication time. The communication topology shows a large number of MPI messages exchanging data in a six-dimensional grid. We also show that relatively large messages are used in MPI communication, reaching up to 256MB. As a communication-bound application, we found that using OpenMP in Vlasiator is critical for eliminating intra-node communication. Our results provide important insights for optimizing Vlasiator for the upcoming Exascale machines.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=307804\">Jennifer Faj<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_209704.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_209704.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=209704\">Jeremy J.

A Gray-Scott 2-variable diffusion-reaction application using a memory-bound 7-point stencil kernel is run on Frontier, the first exascale supercomputer. We evaluate the feasibility, performance, scaling, and trade-offs of (i) the computational kernel on AMD's MI250x GPUs, (ii) weak scaling up to 4,096 MPI processes\/GPUs or 512 nodes, (iii) parallel I\/O write using the ADIOS2 library bindings, and (iv) Jupyter Notebooks for interactive data analysis.<br><br>We will discuss our results which show that although Julia generates a reasonable LLVM-IR kernel, there is nearly a 50% performance difference with native AMD HIP stencil codes on GPU. We observed near-zero overhead when using MPI and parallel I\/O bindings to system-wide installed implementations. Consequently, Julia emerges as a compelling high-performance and high-productivity workflow composition strategy as measured on Frontier.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_987973.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_987973.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=987973\">William F.

To address this, a thorough I\/O analysis is crucial to identify potential bottlenecks. However, the multitude of metrics makes it difficult to pinpoint the causes of low I\/O performance. In this work, we analyze three scientific workloads using three widely accepted I\/O metrics. We demonstrate that different metrics uncover different I\/O bottlenecks, highlighting the importance of considering multiple metrics for comprehensive I\/O analysis.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_184593.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_184593.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=184593\">Izzet Yildirim<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_096693.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_096693.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=096693\">Hariharan Devarajan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_220663.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_220663.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=220663\">Anthony Kougkas<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_472143.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_472143.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=472143\">Xian-He Sun<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=380788320404508983\">Illinois Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_917443.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_917443.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=917443\">Kathryn Mohror<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost163\"><span style=\"display: none;\"><!-- cal-file sess291--rpost163.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost163\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Often times, trace collection tools provide a graphical tool to analyze the trace output. However, these GUI-based tools only support specific file formats, are difficult to scale when the data is large, limit data exploration to the implemented graphical views, and do not support automated comparisons of two or more datasets. In this poster, we present a pandas-based Python library, Pipit, which can read traces in different file formats (OTF2, HPCToolkit, Projections, Nsight, etc.) and provide a uniform data structure in the form of a pandas DataFrame. Pipit provides operations to aggregate, filter, and transform the events in a trace to present the data in different ways. We also provide several functions to quickly identify performance issues in parallel executions.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=623504\">Alexander Movsesyan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=423504\">Rakrish Dhakal<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=723504\">Aditya Ranjan<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=523504\">Jordan Marry<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=248983\">Onur Cankur<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_534543.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_534543.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=534543\">Abhinav Bhatele<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost205\"><span style=\"display: none;\"><!-- cal-file sess291--rpost205.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost205\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This work focuses on characterizing iPIC3D\u2019s communication efficiency through strategic measures like optimal node placement, communication and computation overlap, and load balancing. Profiling and tracing tools are employed to analyze iPIC3D\u2019s communication efficiency and provide practical recommendations. Implementing optimized communication protocols addresses the Geospace Environmental Modeling (GEM) magnetic reconnection challenges in plasma physics with more precise simulations. This approach captures the complexities of 3D plasma simulations, particularly in magnetic reconnection, advancing space and astrophysical research.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_209704.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_209704.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=209704\">Jeremy Johnathan Williams<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=690204\">Daniel Medeiros<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_072673.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_072673.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=072673\">Ivy Peng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_108863.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_108863.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=108863\">Stefano Markidis<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8657380143009231201\">KTH Royal Institute of Technology, Sweden<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost102\"><span style=\"display: none;\"><!-- cal-file sess291--rpost102.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost102\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, the immense parameter size and complexity of LLMs present significant challenges. This work delves into the exploration and characterization of high-performance interconnects in the distributed training of various LLMs. Our findings reveal that high-performance network protocols, notably RDMA, significantly outperform other protocols like IPoIB and TCP\/IP in training performance, offering improvements by factors of 2.51x and 4.79x respectively. Additionally, we observe that LLMs with larger parameters tend to demand higher interconnect utilization. Despite these findings, our study suggests potential for further optimization in overall interconnect utilization. This research contributes to a deeper understanding of the performance characteristics of LLMs over high-speed interconnects, paving the way for more efficient training methodologies.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=944993\">Hao Qi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=603504\">Liuyao Dai<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=537504\">Weicong Chen<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_625953.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_625953.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=625953\">Xiaoyi Lu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3452173294357587966\">University of California, Merced<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost174\"><span style=\"display: none;\"><!-- cal-file sess291--rpost174.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost174\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This situation makes I\/O performance prediction a strong candidate for using machine learning because of the complex variables involved. However, making a high-quality prediction requires a large amount of equivalent-quality data, and collecting it is a big challenge for most data centers.<br><br>In this project, we explore transfer learning to predict the I\/O performance by utilizing the publicly available I\/O performance data in Darshan logs from the NCSA's Blue Waters supercomputer. We devise a workflow to train a neural network model as a base to predict the POSIX I\/O bandwidth of other clusters (CLAIX18 and Theta). With less than 1% of the data needed to build the base model, our experiment shows that our transfer learning workflow can predict the I\/O bandwidth of another system with a mean absolute error better or equivalent to the state-of-the-art.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=640193\">Dmytro Povaliaiev<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=11293555275586724674\">RWTH Aachen University<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_437573.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_437573.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=437573\">Radita Liem<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=18364340748721367886\">RWTH Aachen University, IT Center<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_367453.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_367453.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=367453\">Julian Kunkel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10119743789000871867\">University of G\u00f6ttingen, GWDG, Germany<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_786453.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_786453.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=786453\">Jay Lofstead<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8983149627912099836\">Sandia National Laboratories<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_491843.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_491843.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=491843\">Philip Carns<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2528856250777415608\">Argonne National Laboratory (ANL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost197\"><span style=\"display: none;\"><!-- cal-file sess291--rpost197.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost197\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

DFToy's accessibility makes it an excellent platform for benchmarking, experimentation and development - allowing developers to research novel algorithms for DFT codes.<br><br>We will show DFToy's use and capabilities in its current state, compare its behavior to a state-of-the-art DFT code, and discuss where we will take the code going forward - including the development of a self-tuning parallel model.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=230904\">Arjen Tamerus<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6001768197196770753\">University of Cambridge<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=470904\">Phil Hasnip<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=10061698975685396687\">University of York, England<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost229\"><span style=\"display: none;\"><!-- cal-file sess291--rpost229.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost229\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

While the kernel is running on the GPU, the CPU cores often remain idle, waiting on the GPU to finish  kernel execution.<br><br>In recent years, several frameworks have been presented that perform automated distribution of workload to both CPU and GPU. While the aforementioned frameworks offer techniques for CPU+GPU workload distribution for regular applications, identifying a performant CPU+GPU workload distribution for irregular applications remains a difficult problem due to workload imbalance and irregular memory access patterns.<br><br>This work evaluates a hybrid CPU+GPU implementation of an irregular workload -- graph link prediction using the Jaccard similarity.  For the graphs that benefit the most from our hybrid CPU-GPU approach, our implementation delivers a 16.4-28.4% improvement over the state-of-the-art Jaccard similarity implementation.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_348483.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_348483.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=348483\">Atharva Gondhalekar<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1270569034457186575\">Virginia Tech<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=974253\">Paul Sathre<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1270569034457186575\">Virginia Tech<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_712143.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_712143.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=712143\">Wu-chun Feng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=1270569034457186575\">Virginia Tech<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost221\"><span style=\"display: none;\"><!-- cal-file sess291--rpost221.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost221\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Preserving data locality allows CNN models to reduce the number of training parameters, and hence their training time, while achieving high classification accuracy. However, contemporary methods of quantum machine learning do not possess effective methods for exploiting data locality, due to the lack of a generalized and parameterizable implementation of quantum convolution. In this work, we propose variational quantum classification techniques that leverage a novel multidimensional quantum convolution operation with arbitrary filtering and unity stride. We provide the quantum circuits for our techniques alongside corresponding theoretical analysis. We also experimentally demonstrate the advantage of our method in comparison with existing quantum and classical techniques for image classification in staple multidimensional datasets using state-of-the-art quantum simulations.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=133804\">Mingyoung Jeng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=852693\">Alvir Nobel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=233804\">Vinayak Jha<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=333804\">David Levy<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=433804\">Dylan Kneidel<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=432693\">Manu Chaudhary<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=533804\">Ishraq Islam<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_464863.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_464863.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=464863\">Esam El-Araby<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8431928408615703008\">University of Kansas<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess307\" ssid=\"rpost120\"><span style=\"display: none;\"><!-- cal-file sess291--rpost120.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost120\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

This is accomplished by transferring technology and knowledge between academic code waLBerla and industrial code LaBS.<br><br>This poster introduces both software packages and the technology transfer process, resulting in improved CPU and GPU performance and increased interest in energy efficiency.<br><br>LBM are trustworthy alternatives to conventional CFD, showing roughly an order of magnitude performance advantage over Navier-Stokes approaches in comparable scenarios.<br><br>SCALABLE unites waLBerla and LaBS developers to improve both solvers in terms of portability (targeting GPUs for example), energy efficiency scenarios and transferring techniques between the two to achieve high performance, scalability, and energy efficiency.<\/span><\/div><div class=\"info-section

class=\"default-text\">Description<\/span><\/span><span class=\"abstract\">Accelerators based on reconfigurable devices are becoming popular for data analytics in high performance computing and cloud computing systems. However, designing these accelerators is a hard problem. High-Level Synthesis tools can help by generating RTL designs from high-level languages, but they tend to optimize the computational part of the kernel, often not considering data movement and memory accesses.  For many applications, instead, memory operations take a significant part of the overall execution time and can be the actual bottleneck limiting performance, especially when accessing large, possibly remote, memories.<br><br>We propose an approach based on the generation and integration of highly-customizable accelerator caches in order to reduce the latency with which an HLS-generated accelerator accesses external memory through spatial and temporal locality. We integrate it in a state-of-the-art open-source HLS tool and show how our approach allows to easily explore tradeoffs between performance and resource utilization with minimal user effort required.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=820904\">Claudio Barone<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=130904\">Giovanni Gozzi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=268004\">Michele Fiorito<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=640593\">Ankur Limaye<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_512653.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_512653.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=512653\">Antonino Tumeo<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=842463\">Fabrizio Ferrandi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9427049895900320842\">Polytechnic University of Milan<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess307\" ssid=\"rpost207\"><span style=\"display: none;\"><!-- cal-file sess291--rpost207.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost207\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, the large quantity of programming models available which claim to provide performance portability leaves developers with a complex choice when picking a model to use, potentially requiring an intensive effort to test each available model with kernels from their app. In order to better understand the current state of performance portable programming models, this project evaluates seven of the most popular programming models using two memory-bound mini-applications on two leadership-class supercomputers, Summit and Perlmutter. These results provide a useful evaluation of how well each programming model provides true performance portability in real-world usage for memory-bound applications.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=886593\">Joshua H.

Performance of the most popular asynchronous RMA interfaces like MPI RMA and SHMEM has steadily improved over the past years due to better software\/hardware support from the vendors and community-driven programming model standardization efforts. <br>    <br>Current RMA benchmarking efforts are mostly focused on investigating elementary data movement overheads between a process-pair within and across nodes, not considering a specific process topology. Distributed-memory applications on the other hand must deal with overlapped data distributions, which governs the underlying topology of the processes. We discuss the performance of SHMEM and MPI RMA (in comparison with MPI point-to-point) for grid and graph process topologies on NERSC Perlmutter supercomputer, demonstrating average and 99th percentile latencies.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=709704\">Nikodemos Koutsoheras<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=908773\">Sayan Ghosh<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_053843.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_053843.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=053843\">Nathan Tallent<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=068863\">Joshua Suetterlein<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8773977782916723735\">Pacific Northwest National Laboratory (PNNL)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_534543.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_534543.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=534543\">Abhinav Bhatele<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6149098175395179931\">University of Maryland<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost166\"><span style=\"display: none;\"><!-- cal-file sess291--rpost166.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost166\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Traditional HPC users are accustomed to waiting for job execution on a batch scheduling system while new users prefer an interactive terminal such as Jupyter Notebook. To address these evolving requirements, enhancing interactivity is essential. Fine-grained gang scheduling is one potential solution for this problem. This poster presents a scalable inter-node synchronization mechanism that facilitates well-time-aligned synchronization message delivery through broadcast communication for fine-grained gang scheduling in HPC systems. The mechanism improved the application performance by 2.7 times in comparison to the existing implementation, when simultaneously executing two parallel applications on 128 computing nodes with a 500 ms time slice.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=599873\">Hiroki Ohtsuji<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6365010104283069472\">Fujitsu Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=870904\">Erika Hayashi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6365010104283069472\">Fujitsu Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=970904\">Reika Kinoshita<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6365010104283069472\">Fujitsu Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=064583\">Masahiro Miwa<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6365010104283069472\">Fujitsu Ltd<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=080904\">Eiji Yoshida<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=6365010104283069472\">Fujitsu Ltd<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost233\"><span style=\"display: none;\"><!-- cal-file sess291--rpost233.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost233\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Given the emergence of performance portable programming libraries having abstractions for parallelism, new tool support offered by the HPC Software for such sophisticated activities is needed to handle these library abstractions over multiple backends. Addressing this will allow for software sustainability of performance portable libraries. Considering Kokkos, a representative C++-based Performance Portable Library, we focus on (1) a community-driven tool connector subset of the Kokkos Tools offer capability for such sophisticated activities along with (2) an associated tool infrastructure which includes common interfaces and utilities to enable such sophisticated tools. Showcasing this part of Kokkos Tools shows it is capable, lightweight, easy to use, and a viable alternative of such tools supporting specific low-level programming models.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_241473.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_241473.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=241473\">Vivek Kale<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8983149627912099836\">Sandia National Laboratories<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=651153\">David Boehme<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=762828389931586843\">Lawrence Livermore National Laboratory (LLNL)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_760643.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_760643.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=760643\">Kevin Huck<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2854505398367532833\">University of Oregon<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=194104\">Shravan Kale<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=2854505398367532833\">University of Oregon<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=376993\">Vanessa Surjadidjaja<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8983149627912099836\">Sandia National Laboratories<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=476804\">James Brandt<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8983149627912099836\">Sandia National Laboratories<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost122\"><span style=\"display: none;\"><!-- cal-file sess291--rpost122.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost122\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

In this work, we explore the proposed C++26 language standard model for asynchronous parallelism, called std::execution or stdexec, powered with stdpar, std::mdspan, among other C++23 features, to port and analyze multiple scientific HPC applications on CPUs and GPUs. These applications include sequence alignment codes from ADEPT and heat transfer from AMReX. Our experiments depict near-native performance for our ported implementations on NVIDIA A100 GPUs running on the Perlmutter supercomputer. We also study and analyze the data transfer traffic patterns and overheads between the host and device for stdpar and provide helpful insights in application performance. Finally, we discuss some challenges and limitations encountered while porting these apps to C++26 with stdexec, as well as their workarounds, until the stdexec is fully integrated and function in the NVHPC compilers.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_547804.jpg --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_547804.jpg\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=547804\">Muhammad Haseeb<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16190860808598276487\">National Energy Research Scientific Computing Center (NERSC)<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=357804\">Weile Wei<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16190860808598276487\">National Energy Research Scientific Computing Center (NERSC)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=366263\">Jack Deslippe<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16190860808598276487\">National Energy Research Scientific Computing Center (NERSC)<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=779573\">Brandon Cook<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16190860808598276487\">National Energy Research Scientific Computing Center (NERSC)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost137\"><span style=\"display: none;\"><!-- cal-file sess291--rpost137.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost137\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, the limited number and quality of qubits poses a challenge for practical usage of near-term quantum computation. Circuit cutting is a technique to decrease the size of circuits at the cost of an additional sampling overhead. This can enable executing problems larger in size and with higher-quality outcomes than what available quantum hardware would otherwise support.<br><br>Here, we use the Circuit Knitting Toolbox (CKT) to demonstrate two applications of circuit cutting. To scale these workloads up to hundreds of qubits, we use Quantum Serverless \u2013 a new framework for distributing computationally expensive workloads in the cloud.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=446804\">Caleb Johnson<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16677086092801021240\">IBM Research<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=327804\">Bryce Fuller<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16677086092801021240\">IBM Research<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=427804\">Jim Garrison<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16677086092801021240\">IBM Research<\/a><\/div><\/span><\/div><\/div><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=527804\">Jennifer Glick<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=16677086092801021240\">IBM Research<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost131\"><span style=\"display: none;\"><!-- cal-file sess291--rpost131.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost131\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We propose a programming model using the API provided by OpenMP to target quantum devices, which provides an easy-to-use and efficient interface for HPC applications to utilize quantum compute resources. We have implemented a variational quantum eigensolver using the programming model, which has been tested using a classical simulator.

but the need for supercomputer in JAXA for numerical simulation and data processing etc. continues to rise. Until now, general-purpose CPUs have been exclusively used, but there is an urgent need to seriously consider the use of dedicated computers and new architectures. One candidate is a quantum computer.<br><br>In order to study the feasibility of a quantum computer as a candidate for a new architecture, the Gate-Model Quantum Computer Study Group was established with JSS3: JAXA Supercomputer System generation 3 users as the main members, which examined the possibility of applying Gate-Model Quantum Computing technology to JAXA's technical problem areas, and will assist management in making mid to long-term decisions regarding computing resources.<br><br>The Group organized use cases created in workshops and gained insight into the effects of utilizing quantum technology.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div

challenges in sharing resources through conventional virtualization methods among end users. Moreover, the extensive data required by AI often cannot be conveniently co-located with the compute resources, resulting in costly and unsuitable migration attempts. To address these issues, Radium offers a userspace framework employing process virtualization, thread execution migration, and distributed shared memory. By leveraging Radium, an unmodified application binary operates in an encapsulated virtualized environment and its execution can be transparently distributed among nodes where resources are located.

Generally, algorithm-specific architectures are implemented on the FPGAs, and there is very little flexibility. Moreover, mapping a quantum algorithm onto its equivalent FPGA emulation architecture is challenging. In this work, we present an automation framework for converting quantum algorithms\/circuits to their equivalent FPGA emulation architectures. The framework processes quantum circuits represented in Quantum Assembly Language (QASM) and derives high-level descriptions of the hardware emulation architectures for High-Level Synthesis (HLS) on HPRCs. Experimental results show that the framework-generated architectures deployed on an HPRC perform faster than a state-of-the-art software simulator.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Authors<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=060904\">Anshul Maurya<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9465079623599954579\">Florida Institute of Technology<\/a><\/div><\/span><\/div><\/div><div class=\"not-presenting presenter-details\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=260904\">Naveed Mahmud<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9465079623599954579\">Florida Institute of Technology<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name evtt107\">Posters<\/div><div class=\"event-type-name sstype134\">Research Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Tuesday, 14 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-14T17:00:00Z\">10am<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T00:00:00Z\">5pm<\/span><span class=\"timezone\" utc_time=\"2023-11-14T17:00:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess291\" ssid=\"rpost225\"><span style=\"display: none;\"><!-- cal-file sess291--rpost225.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess291--rpost225\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We argue that SMTLIB, the language specification for SMT solvers, is well suited for exposing hardware implementations.<br><br>Using our method, we create a formal specification of the tensor cores on NVIDIA's Volta architecture. We confirm many of the findings of previous studies on tensor cores, but also identify two discrepancies: we find that the hardware does not use IEEE-754 round-to-zero for accumulation and that the 5-term accumulator requires 3 extra bits for carry out since it does not normalize intermediate sums.<br><br>The work will be presented in person using the poster as a visual aid.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=082393\">Benjamin Valpey<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=9182826112081074236\">University of Rochester<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:30:00Z\">3:30pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:39:00Z\">3:39pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T22:30:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostg111\"><span style=\"display: none;\"><!-- cal-file sess308--spostg111.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostg111\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

To address this issue, traditional approaches integrate lossy compression directly into GPU-aware collectives, which still suffer from serious issues such as underutilized GPU devices and uncontrolled data distortion. <br><br>In this poster, we propose GPU-LCC, a general framework that designs and optimizes GPU-aware, compression-enabled collectives with well-controlled error propagation. To validate our framework, we evaluate the performance on up to 512 NVIDIA A100 GPUs with real-world applications and datasets. Experimental results demonstrate that our GPU-LCC-accelerated collective computation (Allreduce), can outperform NCCL as well as Cray MPI by up to 4.5X and 20.2X, respectively. Furthermore, our accuracy evaluation with an image-stacking application confirms the high reconstructed data quality of our accuracy-aware framework.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=732593\">Jiajun Huang<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=5008955996537354022\">University of California, Riverside<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:39:00Z\">3:39pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:48:00Z\">3:48pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T22:39:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostg114\"><span style=\"display: none;\"><!-- cal-file sess308--spostg114.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostg114\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Most compression algorithms are more computationally complex, requiring more processing power and time to compress and decompress data. However, these algorithms tend to achieve higher compression ratios resulting in smaller compressed data sizes. Real-time streaming applications demand high data throughput. Therefore, striking a right balance between compression efficiency and computational complexity is essential. This poster explores two key aspects: interpolation method of 'sz3' algorithm for data reconstruction and the application of 'szx' algorithm on a 'Region of Interest(ROI)' - where a lesser data distortion is needed. We perform a through evaluation using NYX scientific dataset. Experiments show that compression ratio is improved by ~2x. Compression and decompression rates are improved by ~5-7x when contiguous ROI is preserved and only certain recursive levels of sx3 are processed.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=930404\">Avinash Kethineedi<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=3939629011957553511\">Clemson University<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:48:00Z\">3:48pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T22:57:00Z\">3:57pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T22:48:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostg122\"><span style=\"display: none;\"><!-- cal-file sess308--spostg122.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostg122\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

In recent years, synchronous checkpointing, which blocks the application until checkpoints are persisted to external storage, suffers rising synchronization overheads at scale, resulting in little forward progress by the application. Therefore, asynchronous checkpointing has become more popular by quickly capturing checkpoints locally and flushing them in the background concurrently alongside the application. State-of-the-art solutions like VELOC utilize a file-per-process strategy, which is difficult for users and parallel file systems to manage. We implement a tunable N-to-M aggregation strategy within VELOC, obtaining 2.5x greater throughput than state-of-the-art aggregation library ADIOS2 and 1.5x higher throughput than the naive N-to-1 aggregation currently supported by VELOC.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><!-- presenter-pic wp_presenter_img_909593.png --><img decoding=\"async\" align=\"left\" class=\"presenter-pic\" src=\"\/wp-content\/linklings_snippets\/presenter_pics\/wp_presenter_img_909593.png\" \/><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=909593\">Mikaila J.

Data accesses to the distant data sources cause long latency to the applications and can be further delayed due to limited network bandwidth. XCache-based in-network regional data caching system stores scientific data and can reduce the network traffic and access latency. We examine the established Southern California Petabyte Scale Cache (So Cal Cache) and the newly deployed Chicago Regional Cache (Chicago Cache) for a high-energy physics experiment to analyze cache utilization trends and compare regional data access patterns. The results of the cache utilization trends show that the cache contributed to sharing a majority of data, and regional differences can be explained by the comparative study. Additionally, predictions of cache behavior show low error values in both regions, providing a useful tool for future resource planning.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=362804\">Ronak Monga<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=817396808794328686\">Indiana University<\/a><\/div><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=13588942530137301385\">Lawrence Berkeley National Laboratory (LBNL)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:15:00Z\">4:15pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:24:00Z\">4:24pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T23:15:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostu101\"><span style=\"display: none;\"><!-- cal-file sess308--spostu101.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostu101\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

The viability of offloading inference to the cloud, considering latency between the car and data center, is questioned. We introduce a Cloud-Aided Real-time Inferencing Framework, integrating with Donkeycar and distributing computational load between cloud and edge. Utilizing Raspberry Pi 4 for edge inferencing and NVIDIA Triton Inference Server for the cloud, we demonstrate the framework's advantages, particularly in RNN performance, which achieved 90% autonomy. Our study includes a scaled car navigating obstacles, assessing factors like speed, resources, latency, and autonomy score. The system's performance shows faster inference time, eliminating bottlenecks, and processing 42 frames per second in the cloud, 11 times faster than on the edge. The poster will detail the strengths, limitations, and potential of leveraging cloud resources in real-time edge environments, focusing on autonomy scores and latency trade-offs.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=694804\">Kyle Zheng<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=17609504613707546584\">National Science Foundation (NSF)<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:24:00Z\">4:24pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:33:00Z\">4:33pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T23:24:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostu102\"><span style=\"display: none;\"><!-- cal-file sess308--spostu102.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostu102\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

We provide the first systematic investigation of the reduce operation on the Cerebras Wafer-Scale Engine (WSE) using the Cerebras SDK. We improve upon existing reduce implementations by up to 5x in certain settings. We show that using at most three different implementations we can achieve performance at most 1.38x slower than an optimal reduction tree. Finally, we provide an allreduce that outperforms patterns like ring or butterfly by up to 2x. <br><br>We will (a) cover unique features of the Cerebras WSE, (b) introduce a model to accurately predict performance on the hardware, (c) discuss different reduce implementations, (d) analyze the results of running them using an accurate simulator and compare them against an optimal reduction tree, (e) show how to extend them to an efficient allreduce.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=187004\">Piotr Luczynski<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=8651363363052116427\">ETH Z\u00fcrich<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:33:00Z\">4:33pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:42:00Z\">4:42pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T23:33:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostu109\"><span style=\"display: none;\"><!-- cal-file sess308--spostu109.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostu109\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

However, the molecular search space is enormous and the common protein docking methods are still computationally intractable without access to the world\u2019s largest supercomputers. Instead, researchers are using AI methods to provide a powerful new tool to help guide docking campaigns. In such approaches, a lightweight surrogate model is trained and then used to identify promising candidates for screening.  We present ParslDock, a Python-based pipeline using the Parsl parallel programming library and the K-Nearest Neighbors machine learning model to screen a huge molecular space of molecules against arbitrary receptors. We achieved a 38X speedup with ParslDock compared to a brute-force docking approach.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span class=\"default-text\">Author<\/span><\/div><div class=\"presenter-details-list\"><div class=\"presenter-details presenting\"><div class=\"pic-auth-container\"><span class=\"empty presenter-pic\"><\/span><div class=\"presenter-name\"><a href=\"\/presenter\/?uid=100904\">John Raicu<\/a><\/div><span class=\"professional-info\"><div class=\"presenter-institution\"><a href=\"\/organization\/?inst=4758609107779219141\">University of Chicago<\/a><\/div><\/span><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"right-col\"><div class=\"event-type-sect info-section\"><span class=\"info-label\"><span class=\"default-text\">Event Type<\/span><\/span><span class=\"event-types\"><div class=\"event-type-name sstype114\">ACM Student Research Competition: Graduate Poster<\/div><div class=\"event-type-name sstype115\">ACM Student Research Competition: Undergraduate Poster<\/div><div class=\"event-type-name evtt107\">Posters<\/div><\/span><\/div><div class=\"info-section presentation-date-sect\"><span class=\"info-label\">Time<\/span><span class=\"presentation-date\">Wednesday, 15 November 2023<\/span><span class=\"presentation-time\"><span class=\"dateTimeInfo start-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:42:00Z\">4:42pm<\/span> - <span class=\"dateTimeInfo end-time\" date_format=\"%A, %-d %B %Y\" time_format=\"%l%P\" utc_time=\"2023-11-15T23:51:00Z\">4:51pm<\/span><span class=\"timezone\" utc_time=\"2023-11-15T23:42:00Z\"> MST<\/span><\/span><span class=\"agenda-item\" psid=\"sess308\" ssid=\"spostu111\"><span style=\"display: none;\"><!-- cal-file sess308--spostu111.ics --><a class=\"ical-link\" href=\"\/wp-content\/plugins\/linklings_wp_program\/get_cal\/?id=sess308--spostu111\"><\/a><\/span><span class=\"agenda-add-button agenda-button clickable\" name=\"add_to_agenda\" role=\"switch\" style=\"display: none;

Thus, the time to serve a function in the Function-as-a-Service (FaaS) paradigm, is dependent on the time to load the necessary container.  FaaS platforms try to avoid \"cold-starts'', instead pre-loading containers to serve workload. We focus on the problem of rapidly loading Python environments in the  Globus Compute (previously funcX) platform.  Globus Compute is unique in that it is deployed on HPC systems and thus suffers from costs of shared file systems.  We evaluate containers and microvmms (Docker and Firecracker) and propose a new approach using lightweight Python Unikernels.  We show considerable speed up in cold-start times using Unikernels.<\/span><\/div><div class=\"info-section presenter-details-sect\"><div class=\"author\"><div class=\"info-label\"><span
