Summary:

The intent of this workshop is to provide a forum to discuss multi-core programming techniques as they apply to HPC applications running on commodity Linux clusters. The workshop is organized by technical staff members at the Texas Advanced Computing Center (TACC) who have a history of deploying and supporting large-scale Linux clusters for a diverse academic community. With clock speed increases becoming increasing smaller between processor generations, vendors have naturally turned to multi-core solutions to provide increased performance. The multi-core environment imposes additional challenges to HPC users and this workshop will present invited presentations followed by user discussion on a range of topics related to multi-core processors (including, but not limited to):

  • Architecture overviews
  • Hybrid programming - performance enhancements for example applications
  • Memory access patterns, effects of latency hiding
  • Job scheduling placement - MPI Performance on-node vs. off-node
  • Processor and memory affinity
  • Recommended Linux kernel configurations
  • Folks interested in participating in the workshop are invited to contact Karl Schulz for more information or to propose a presentation.
