Enabling Low-Overhead Hybrid MPI/OpenMP Parallelism with MPC

Abstract. With the advent of multicore- and manycore-based supercomputers, parallel programming models like MPI and OpenMP become more widely used to express various levels of parallelism in applications. But even though combining multiple models is possible, the resulting performance may not reach expected results. This is mainly due to collaboration issues between the runtime implementations. In this paper, we introduce an extended taxonomy of hybrid MPI/OpenMP programming and a new module to the MPC framework handling a fully 2.5-compliant
