SUMMARY:Featured Talk - Programming DOE Systems: Exascale and Beyond
DESCRIPTION:Workshop\n\nFeatured Talk - Programming DOE Systems: Exascale 
 and Beyond\n\nde Supinski\n\nProgramming exascale systems was seen as a ma
 jor challenge at the start of the efforts to reach that level of performan
 ce. 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 emergin
 g C++ abstraction layers such as Kokkos and RAJA often use the familiar MP
 I + OpenMP model in their backends. Thus, this talk will describe the impl
 ementation of the MPI + OpenMP model on the El Capitan and Frontier DOE ex
 ascale systems as while as how OpenMP has evolved, and will continue to ev
 olve, to remain a key part of the large-scale programming ecosystem.\n\nSe
