DescriptionThe vast majority of production parallel scientific applications today use MPI and run successfully on the largest systems in the world. At the same time, the MPI standard itself is evolving to address the needs and challenges of future extreme-scale platforms as well as applications. This tutorial will cover several advanced features of MPI, including new MPI-3 features, 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 2D and 3D stencil computation, derived datatypes, one- sided communication, hybrid (MPI + shared memory) programming, topologies and topology mapping, and neighborhood and nonblocking collectives. 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.
