PERFORMANCE TUNING FOR MULTI-CORE ARCHITECTURES

May 14, 2008 - May 15, 2008
9:30 am - 5:30 pm
Ohio Supercomputer Center

This two-day course demonstrates several techniques for improving the performance of applications on multi-core systems, such as OSC's Glenn Opteron cluster. These techniques involve taking advantage of features common to most modern microprocessors, including multi-level caches and multiple pipelined functional units, as well as parallelism within and across nodes.

Topics covered in the course will include:

Day One: Single-Processor Performance

• Single-processor performance measurement and analysis tools
  • Timing
  • Compiler reports
  • Profiling
  • Hardware performance counters
• Processor and memory architecture
  • Processor architecture features
  • Hierarchical memory and caching
• Single-processor performance tuning techniques
  • Inlining
  • Loop Optimization
  • Memory Optimization
  • Floating point behavior
  • Optimized math libraries
Day Two: Multi-core and Parallel Performance
• Parallel performance measurement and analysis tools
  • Timing
  • Profiling
• Threaded performance
  • Threaded programming interfaces
  • Common threaded performance bottlenecks
• Message passing performance
  • Message passing programming interfaces
  • Interconnect characteristics
  • Common message passing performance bottlenecks

Familiarity with UNIX and either Fortran 90 or C/C++ is required. Knowledge of a parallel programming method (eg. MPI or OpenMP) is helpful but not required.

Those interested in improving the performance of their applications on multi-core systems, including PCs and workstations as well as supercomputers
