In the MPITypes paper (Processing MPI Datatypes Outside MPI), page 7: Test: Vector Element type: float MPICH2: 1788.85 MB/sec OpenMPI: 1088.01 MB/sec <- * MPITypes: 1789.37 MB/sec Manual Copy: 1791.59 MB/sec
Test: YZ Face Element type: float MPICH2: 145.32 MB/sec OpenMPI: 93.08 MB/sec <- * MPITypes: 145.32 MB/sec Manual Copy: 143.68 MB/sec Size: 0.25 MB Extent:63.99 MB The paper can be downloaded at: http://press.mcs.anl.gov/mpitypes/ Is anyone working on this performance issue, or has it been fixed already?? If not, I will check with the authors and try to get the source code of the benchmark... Rayson
