MPICH2 version 0.9.8-12 is available for the gnu compilers and uses the OpenFabrics stack to access the infiniband network. To setup the intel compilers for openmpi, execute one of following based on your shell:

• source /usr/local/profile.d/mpich2-gnu.csh ( for c-shell users)
• source /usr/local/profile.d/mpich2-gnu.sh( for bourne shell users)

Once setup, users should find in their path mpicc, mpicxx, mpif90 and mpif77.  See the MOAB documentation for an example of using MPICH2 with MOAB submission scripts .
