Welch %B Communicating Process Architectures 2004 %X 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.
