Advanced MPI: I/O and one-sided communication

Research output: Chapter in Book/Report/Conference proceedingConference contribution


This tutorial is about advanced use of MPI, in particular the parallel I/O and one-sided communication features added in MPI-2. Implementations are now available both from vendors and from open-source projects so that these MPI-2 capabilities can now really be used in practice. The tutorial will be heavily example-driven. For each example we introduce concepts, describe the problem being solved, then walk through the code and its execution.Examples were chosen to cover scenarios seen in real applications, such as 1D and 2D mesh decomposition, checkpointing of sparse data structures, and providing atomic access to shared memory data structures. Attendees will leave the tutorial with both an understanding of these advanced concepts and a collection of working example codes that they are familiar with and have seen in action. This will prepare them for applying these concepts in their own applications.
