Information:
LAM is a freeware implementation of the Message

It is especially friendly to clusters. The program
includes a persistent runtime environment for
parallel jobs, support for all of MPI-1
(except MPI_Canceling sent messages), support for
a good chunk of MPI-2 and support for MPI-IO
(provided by the ROMIO package from Argonne
National Labs).

current stable release. LAM/MPI 6.4.x is also
available and includes support for Interoperable MPI.
