Running MPI Jobs

Open MPI version 1.4.1 is installed on all the nodes. The default MPI that comes with CentOS was not working that's why we build MPI from source as explained here. mpicc, mpirun and other MPI programs are installed under /usr/local/bin which is in your path. /usr/local/lib is added to one of the files under /etc/ld.so.conf.d to solve libmpi.so.0 not found issue.

Here are the instructions for running "Hello world" from MPI Tutorial.
