Open MPI on Caviness
IT provides templates for two job script variants for the mpi parallel environment on Farber located in /opt/templates/slurm/generic/mpi/openmpi
- OpenIB Verbs variant: openmpi-ib.qs
- This is a batch job template for a program using multiple processor cores/threads on one or more nodes. This particular variant should be used with Open MPI or another MPI library that is tightly-integrated with Slurm.
You may copy and customize these templates to provide the best performance when running your Open MPI applications. See Running Applications on Caviness for details about resources.
It is a good idea to periodically check in
/opt/templates/slurm/generic/mpi for changes in existing templates, or the addition of new templates, designed to provide the best performance on Caviness.
