Most contemporary shared memory systems expose a non-uniform memory architecture (NUMA) with implications on application performance. However, the OpenMP programming model does not provide explicit support for that. This 30-minute live webinar will discuss the approaches to getting the best performance from OpenMP applications on such machines. We will motivate this talk with practical examples showing best practices.

What you will gain from joining this webinar:

  • An understanding of the characteristics of cc-NUMA architectures
  • An understanding of the OpenMP Thread Affinity model
  • An understanding of the Operating System mechanisms of memory placement
  • Learn how  to put all this together for performance optimization
  • See practical examples illustrating best practices
