Parallel programming model for the Epiphany many-core coprocessor using threaded MPI

•We investigate the use of MPI for programming the Epiphany RISC array processor.•A threaded MPI implementation adapted for coprocessor offload is presented.•Existing MPI code for four scientific applications was re-used with minimal changes.•Demonstrated performance exceeds 12 GFLOPS with an effici...
