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.
