A Multi-node MPI Implementation on the CellBE Processor

Due to the heterogeneous multi-core architecture of the CellBE processor, the existing MPI implementation cannot effectively exert the SPE computing capability. In this paper, we design and implement a multi-node MPI programming and running environment for CellBE processor. The MPI communication library prototype, which mainly includes the basic point-to-point communication and the multicast communication operations, is implemented in this cell-MPI model. By this work, the programmers can exploit the SPE´s computing capability to improve the program running efficiency using the traditional MPI programming model; the burden of porting application to the CellBE processor is much reduced. The experimental results show that the presented MPI programming model not only exerts the SPE´s computing capability but also keeps the efficient MPI communication performance.
