Open MPI is a Message Passing Interface (MPI) library project combining technologies and resources from several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI). It is used by many TOP500 supercomputers including Roadrunner, which was the world's fastest supercomputer from June 2008 to November 2009, and K computer, the fastest supercomputer since June 2011.
The Open MPI Project is an open source MPI-2 implementation that is developed and maintained by a consortium of academic, research, and industry partners.

Load SGE module
The following Modules files should be loaded for this package:
For GNU:
module load openmpi/openmpi-gnu
For Intel:
module load openmpi/openmpi-intel
Parallel Environment
Use the openmpi parallel environment in your job script (example for a 4 slot job)
#$ -pe openmpi 4
Submit Script
To enable verbose Grid Engine logging for OpenMPI, add the following the mpirun command in the job script --mca pls_gridengine_verbose 1, for example:
#!/bin/bash #$ -S /bin/bash #$ -cwd # #$ -N j_openmpi_hello #$ -pe openmpi 4 #$ -l h_rt=00:20:00,s_rt=0:18:00 #$ -j y # #$ -M USERID@uab.edu #$ -m eas # # Load the appropriate module files . /etc/profile.d/modules.sh module load openmpi/openmpi-gnu #$ -V mpirun --mca pls_gridengine_verbose 1 -np $NSLOTS hello_world_gnu_openmpi
