Hiding the latency of MPI communication

As developers spend significant effort performing manual latency optimizations, the goal of Van Man Nguyen Ph.D Thesis is to automatically provide maximal communication overlap for MPI communication (collective, point-to-point and RMA Put/Get operations). A method that moves operations and their completion (e.g. Isend/Wait) as far apart as possible in the program while preserving memory consistency is under development.
