MPI Sessions: Second Demonstration and Evaluation of MPI Sessions Prototype

MPI Sessions presents a new paradigm for applications to use MPI functionality within an application. This paradigm offers the promise of more flexible ways for applications to express the capabilities they require from MPI at a fine grain level. This report presents a second evaluation of a prototype implementation of the MPI Sessions proposal, including additional development work on the prototype and investigations using Sessions in the DASK data analytics framework.

RMA-MT Benchmarks

The RMA-MT benchmarks are a suite of performance tests for multi-threaded Message Passing Interface (MPI) Remote Memory Access (RMA) implementations. The suite includes tests for bandwidth and latency with any number of threads. This suite was originally developed and release by Sandia National Laboratory. LANL modifications to the suite include a complete re-write of much of the source code, bi-directional bandwidth, and message rate tests.
