Title
Filling in the gaps between applications and OpenMP for in-node programming on exascale systems
Abstract
OpenMP is a defacto directive-based standard for on-node programming which has become critical to achieve performance in DOE leadership-class HPC systems such as Summit, and the upcoming exascale system, Frontier, at Oak Ridge National Laboratory. This talk will focus on the successes and challenges of using OpenMP to take advantage of the in-node parallelism (multi-cores, accelerators, etc.) and how optimizing compilers/runtimes can help address some of these challenges in the context of performance portability across systems.
