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.　©　2010　IEEE.
