Towards gaining the performance improvement benefited from threaded MPI while supporting MPI standard well, in this paper, we propose a thread-based MPI program accelerator (MPIActor). MPIActor is a transparent middleware to assist general MPI libraries. People can choose to adopt or abandon MPIActor freely in compiling time for any MPI program (Currently only support C code). With the join of MPIActor, in each node, the MPI processes will be mapped as several threads of one process, and the intra-node point-to-point communication and collective communication will have been enhanced by take advantage of thread based mechanism. We have implemented the point-to-point communication module of our design and evaluated it on a real platform. Comparing with MVAPICH2, the experimental results of OSU PINGPONG benchmark show a significant performance improvement from 114% to 321% for transferring messages which size is between 4KB and 2MB. |
