DESCRIPTION:Optimizing High-Performance Linpack for Exascale Accelerated A
 rchitectures\n\nWe detail the performance optimizations made in rocHPL, AM
 D's open-source implementation of the High-Performance Linpack (HPL) bench
 mark targeting accelerated node architectures designed for exascale system
 s such as the Frontier supercomputer. The implementation leverages the hig

 \nUnified Communication Optimization Strategies for Sparse Triangular Solv
 er on CPU and GPU Clusters\n\nThis paper presents a unified framework for 
 reducing communication costs of sparse triangular solvers (SpTRSV) on CPU 
 and GPU clusters. The proposed framework builds upon a 3D communication-av
 oiding process layout that distributes a sparse triangular matrix into a 3
 D layout consisting of 2D grids. T...\n\n\nYang Liu and Nan Ding (Lawrence

 Regular Two-Dimensional Block-Cyclic Sparse Direct Solver on Distributed H
 eterogeneous Systems\n\nSparse direct solvers play a vital role in large-s
 cale high performance computing in science and engineering. Existing distr
 ibuted sparse direct methods employ multifrontal/supernodal patterns to ag
