| Abstract;MPI (Message Passing Interface) performance on the Earth Simulator is presented. Performance of MPISend, MPIBarrier, MPI RMA functions, and some programs of the exchange pattern have been evaluated on the Earth Simulator using the MPI benchmark program library. Regarding MPI performance on the Earth Simulator, the maximum throughput of the intranode communication is 14.8GB/s, and that of the internode communication is 11.8GB/s. The cost of MPIBarrier call on the condition that the number of MPI-processes per PN is 1 is about 3.3 microseconds, and MPIBarrier has excellent scalability. It has been also confirmed that programming using MPI RMA functions is suitable to program complicated communication patterns such as the exchange pattern. (author abst.) |
