Abstract: To understand MPI, we start from some fundamental, small programs that reflect idioms at work in large-scale, bulk-synchronous parallel programs.  MPI offers the ability to move data between peer processes with collective, point-to-point, remote-memory, and I/O operations. In this seminar, we will start with small subsets of MPI, explain how they work, then describe their implications on the design, implementation, and optimization of underlying MPI implementations.   As such, we will touch on small subsets of the standard only.

Future editions of this CUP-ECS seminar will build on the top-to-bottom view of operations and APIs’ syntax and semantics, as well as underlying rules and norms that pervade the MPI standard.  Continued attention to the interactions of applications, runtimes, and networks will inform this and the future lectures too, including emergent heterogeneity (accelerators) and complexity of managing networks, accelerators, multi-core CPUs, and application codes.
