-If you plan to run jobs on any queue except the Infiniband (IB) queue, e.g. rcc-30d, rcc-mc-30d, where all nodes are interconnected with 1g Ethernet, then you can use either OpenMPI or MPICH2 (you cannot use MVAPICH2). If you plan to run jobs on the Infiniband queue (rcc-ib-30d), then you can use OpenMPI (same compilation as for non-IB jobs) or MVAPICH2, but you should not use MPICH2, because doing that will cause your job to use Ethernet, even if it runs on the IB nodes.

MPICH is outdated and is not tightly integrated with the queueing system; therefore, we do not recommend its use. However, if your application requires MPICH (and it does not work with MPICH2), you can use these commands with the full path, e.g. /usr/local/pgi/linux86-64/2012/mpi/mpich/bin/mpicc, /usr/local/pgi/linux86-64/2012/mpi/mpich/bin/mpirun, etc.

-For csh/tcsh:
+* OpenMPI 1.8.4, using Intel 2013_sp1.0.080 compilers, available in module OpenMPI/1.8.4-iccifort-2013_sp1.0.080. To use it, load the module with
 <pre class="gcommand">
-setenv MV2_SMP_USE_CMA 0
+module load OpenMPI/1.8.4-iccifort-2013_sp1.0.080
 </pre>
-These directories are NOT in users’ default path. To use these installations of MVAPICH2 you need to use the full path to the executables.
-NOTE We recommend using MVAPICH2 for applications that have a lot of internodal communication, which can benefit from the high-speed, low-latency Infiniband interconnect.
-For information on how to run executables linked to MVAPICH2, please refer to [[Running Jobs on zcluster]].
+Once the appropriate module is loaded, you can compile code with '''mpicc''', '''mpic++''', '''mpif90''', etc
+and you can run applications that were linked to the MPI libraries loaded by the module.
