Advanced OpenMP Tutorial

SESSION: Advanced OpenMP Tutorial

EVENT TYPE: Tutorials

TIME: 8:30AM - 5:00PM

Presenter(s):Christian Terboven, Alejandro Duran, Michael Klemm, Ruud van der Pas, Bronis R. de Supinski

ROOM:355-F

ABSTRACT:
With the increasing prevalence of multicore processors, shared-memory programming models are essential. OpenMP is a popular, portable, widely supported and easy-to-use shared-memory model. Developers usually find OpenMP easy to learn. However, they are often disappointed with the performance and scalability of the resulting code. This disappointment stems not from shortcomings of OpenMP but rather with the lack of depth with which it is employed. Our Advanced OpenMP Programming tutorial addresses this critical need by exploring the implications of possible OpenMP parallelization strategies, both in terms of correctness and performance. While we quickly review the basics of OpenMP programming, we assume attendees understand basic parallelization concepts and will easily grasp those basics. We discuss how OpenMP features are implemented and then focus on performance aspects, such as data and thread locality on NUMA architectures, false sharing, and private versus shared data. We discuss language features in-depth, with emphasis on features recently added to OpenMP such as tasking. We close with debugging, compare various tools, and illustrate how to avoid correctness pitfalls.
