SUMMARY:ZeroSum:  User Space Monitoring of Resource Utilization and Conten
 tion on Heterogeneous HPC Systems
DESCRIPTION:Kevin Huck and Allen Malony (University of Oregon)\n\nHeteroge
 neous High Performance Computing (HPC) systems are highly specialized, com
 plex, powerful, and expensive systems.  Efficient utilization of these sys
 tems requires monitoring tools to confirm that users have configured their
  jobs, workflows, and applications correctly to consume the limited alloca
 tions they have been awarded. Historically system monitoring tools are des
 igned for and only available to system administrators and facilities perso
 nnel to ensure that the system is healthy, utilized, and operating within 
 acceptable parameters. However, there is a demand for user space monitorin
 g capabilities to address the configuration validation and optimization pr
 oblem.  We describe a prototype tool, ZeroSum, designed to provide user sp
 ace monitoring of application processes, lightweight processes (threads), 
 and hardware resources on heterogeneous, distributed HPC systems. ZeroSum 
 is designed to be used either as a limited-use porting tool or as an alway
 s-on monitoring library.\n\nTag: Programming Frameworks and System Softwar
