Panel Session: MPI on Post-Exascale Systems

Despite claims that MPI would never be effective for first petascale and now exascale systems, MPI is being used effectively on petascale systems and remains the internode programming model for the upcoming pre-exascale systems. Furthermore, MPI is likely to be a key part of the programming environment for exascale systems. This panel will address the question of whether MPI can continue to be the programming model for extreme-scale systems, or whether post-exascale systems will require either significant additions to MPI or need new programming systems to address both the capabilities of post-exascale systems as well as changing needs of applications. What should change in MPI? What changes could broaden the applicability of MPI? How would those changes impact the use of MPI on average-sized parallel computers?
