All,

I installed MPICH2 (over Infiniband). Here is how to run it.
I believe apps may need to be recompiled to utilize MPI-2 feature..


#!/bin/bash -l
#PBS -N mvapich2test
# The following lines requests 2 CPUs on 2 nodes - ie. 4 CPUs total
#PBS -l nodes=4:ppn=2
#PBS -l walltime=10:00:00
#PBS -q test
# load the mrbayes module - this gets the default (currently 3.1.2)

module load mvapich2

mpdboot -n 8 -f $PBS_NODEFILE
mpiexec -machinefile $PBS_NODEFILE -n 8 <executable>
mpdallexit
