MPI

OpenMPI

This is the primary and recommended MPI version. It supports Ethernet and InfiniBand interconnect, with InfiniBand set as default by means of an OMPI_MCA_… environment variable.

Intel MPI

• Intel MPI Documentation
• I recommend to use the new Hydra MPI process manager. See sec. 2.4 Scalable Process Management System in the Reference Manual. This avoids the need to set up and tear down the older and considerably less stable MPD manager.

MPICH/MPICH2

• Not installed explicitly, but Intel-MPI is based on MPICH2 and provides an MPICH2 runtime environment for precompiled binaries.
