SESSION: Advanced MPI
EVENT TYPE: Tutorials
TIME: 8:30AM - 5:00PM
Presenter(s):William Gropp, Ewing Lusk, Robert Ross, Rajeev Thakur
MPI continues to be the dominant programming model for parallel scientific applications on all large-scale parallel machines, such as IBM Blue Gene and Cray XE/XK, as well as on clusters of all sizes. An important trend is the increasing number of cores per node of a parallel system, resulting in increasing interest in combining MPI with a threaded model within a node. The MPI standard is also evolving to meet the needs of future systems, and MPI 3.0 is expected to be released later this year. This tutorial will cover several advanced features of MPI that can help users program such machines and architectures effectively. Topics to be covered include parallel I/O, multithreaded communication, one-sided communication, dynamic processes, and new features being added in MPI-3 for hybrid programming, one-sided communication, collective communication, fault tolerance, and tools. In all cases, we will introduce concepts by using code examples based on scenarios found in real applications. 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.
