  abstract=      "Various implementations of MPI are becoming available as MPI
     is slowly emerging as the standard API for parallel
     programming on most platforms. The open source
     implementations LAM-MPI and MPICH are the most widely used,
     while commercial implementations are usually tied to special
     hardware platforms. This paper compares these two
     open-source MPI-implementations to one of the commercially
     available implementations, MESH-MPI from MESH-Technologies.
     We find that the commercial implementation is significantly
     faster than the open-source implementations, though LAM-MPI
     does come out on top in some benchmarks."
