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.
