DescriptionThe vast majority of production parallel scientific applications today use MPI and run successfully on the largest systems in the world. Parallel system architectures are evolving to include complex, heterogeneous nodes comprising general-purpose CPUs as well as accelerators such as GPUs. At the same time, the MPI standard itself is evolving to address the needs and challenges of future extreme-scale platforms and applications. This tutorial will cover several advanced features of MPI that can help users program modern systems effectively. Using code examples based on scenarios found in real applications, we will cover several topics including efficient ways of doing stencil computation, derived datatypes, one-sided communication, hybrid programming, topology mapping, neighborhood and nonblocking collectives, and some new features in MPI-4. Attendees will leave the tutorial with an understanding of how to use these advanced features of MPI and guidelines on how they might perform on different platforms and architectures.
