Abstract : MPI-3 provide functions for non-blocking collectives. To help programmers introduce non-blocking collectives to existing MPI programs, we improve the PARCOACH tool for checking correctness of MPI call sequences. These enhancements focus on correct call sequences of all flavor of collective calls, and on the presence of completion calls for all non-blocking communications. The evaluation shows an overhead under 10% of original compilation time.
