MPI

MPI based applications can take advantage of either the mpich2 or openmpi installations available on all cluster nodes.

Invoking mpich2

mpich2 is available as module:

[asrini@node063 ~]$ module load mpich2-x86_64 
[asrini@node063 ~]$ which mpich2version
/usr/lib64/mpich2/bin/mpich2version
[asrini@node063 ~]$ mpich2version 
MPICH2 Version:    	1.2.1
MPICH2 Release date:	Unknown, built on Thu Aug  5 15:27:11 EDT 2010
MPICH2 Device:    	ch3:nemesis

Invoking OpenMPI

openmpi is also available as a module

[asrini@node063 ~]$ module load openmpi-1.5.4-x86_64 
[asrini@node063 ~]$ mpirun --version
mpirun (Open MPI) 1.5.4
