Neither IBM Platform MPI nor Intel MPI are tightly coupled with our scheduler; you must therefore tell <tt>starccm+</tt> which hosts to use by means of a file containing the list of available hosts. To produce this file, we provide the <tt>slurm_hl2hl.py</tt> script, which will output the list of hosts when called with the option <tt>--format STAR-CCM+</tt>. This list can then be written to a file and read by Star-CCM+. Also, because these distributions of MPI are not tightly integrated with our scheduler, you should use options <tt>--ntasks-per-node=1</tt> and <tt>--cpus-per-task=32</tt> when submitting a job. As a special case, when submitting jobs with version 14.02.012 modules on Cedar, one must add <code>-fabric psm2</code> to the starccm+ command line (last line in the below Cedar tab of the starccm_job.sh slurm script) for multi-node jobs to run properly otherwise no output will be obtained. | Neither IBM Platform MPI nor Intel MPI are tightly coupled with our scheduler; you must therefore tell <tt>starccm+</tt> which hosts to use by means of a file containing the list of available hosts.

All module versions on Graham require this option for multi-node jobs. | ||
