MPICH2 version 0.9.8-12 is available for the intel 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:

for c-shell users

source /usr/local/profile.d/mpichv2-intel.csh

for bourne shell users

source /usr/local/profile.d/mpichv2-intel.sh

Don't forget to also source the intel c script or the fortran script.

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.

Running programs with mvapich2

You need a configuration file for the MPD daemons in your home directory ($HOME/.mpd.conf). This file chould contain the following line:

secretword=some_string

The string should be unique to you but not any regular password. In older versions of mvapich2, the string could not start with a number, this should have been fixed. Also chmod 600 $HOME/.mpd.conf or the MPD daemons will not start properly.
