The aim of workshop is to bring together researchers and developers to present and discuss innovative algorithms and concepts in the Message Passing programming model and to create a forum for open and potentially controversial discussions on the future of MPI in the Exascale era. Possible workshop topics include innovative algorithms for collective operations, extensions to MPI, including datacentric models, scheduling/routing to avoid network congestion, “fault-tolerant” communication, interoperability of MPI and PGAS models, integration of task-parallel models in MPI, and use of MPI in large scale simulations.
