| Using the ''openmpi-ib.qs'' job script template found in ''/opt/templates/gridengine/openmpi'' provides the best performance for a parallel MPI run for OpenFOAM applications. Once you have copied the template for your job script (e.g. ''qsub_sowfa.qs''), then edit the following for your OpenFOAM application: | Using the ''openmpi-ib.qs'' job script template found in ''/opt/shared/templates/gridengine/openmpi'' provides the best performance for a parallel MPI run for OpenFOAM applications.
