SUMMARY:Tools for Monitoring CPU Usage and Affinity in Multicore Supercomp
 uters
DESCRIPTION:Workshop\n\nTools for Monitoring CPU Usage and Affinity in Mul
 ticore Supercomputers\n\nHuang, Milfeld, Liu\n\nWithout other naturally ef
 ficient methods to further boost CPU performance,  supercomputer designers
  and vendors have packed more and more physical processors(cores) into HPC
  processors. When working with multi-processor compute nodes, process  and
   thread  affinity/pinning can influence performance in a significant way.
  However, existing tools for monitoring an application's CPU usage and aff
 inity information are sometimes inconvenient and unsatisfying. Three innov
 ative HPC user-support tools, core_usage, show_affinity, and amask, have b
 een designed and implemented to change this status. These tools are helpin
 g HPC users and administrators easily monitor CPU usage and affinity. They
  provide a convenient mechanism for evaluating an application's process sc
 heduling and process occupation on processors, especially on systems with 
 a large core counts.\n\nTag: Workshop Reg Pass, Best Practices, Build Syst
