Featured Talk - Programming DOE Systems: Exascale and Beyond
SessionESPM2 2022: Seventh International Workshop on Extreme Scale Programming Models and Middleware
DescriptionProgramming exascale systems was seen as a major challenge at the start of the efforts to reach that level of performance. Perhaps not surprisingly, despite predictions of the likely dominance of new languages, users of DOE exascale systems still rely heavily on the MPI + OpenMP model that has dominated HPC for several years. Even emerging C++ abstraction layers such as Kokkos and RAJA often use the familiar MPI + OpenMP model in their backends. Thus, this talk will describe the implementation of the MPI + OpenMP model on the El Capitan and Frontier DOE exascale systems as while as how OpenMP has evolved, and will continue to evolve, to remain a key part of the large-scale programming ecosystem.
