We have two flavours of Star-CCM+ installed on our servers: a double precision one, and a mixed precision one. You will first need to figure out which version is best suited for your computations. The <tt>starccm</tt> module is the double-precision flavour, while the <tt>starccm-mixed</tt> module is the mixed precision flavour. Star-CCM+ comes bundled with two different distributions of MPI: [https://www.ibm.com/developerworks/downloads/im/mpi/index.html IBM Platform MPI] and [https://software.intel.com/en-us/intel-mpi-library Intel MPI]. The default distribution is IBM Platform MPI. However, this distribution does not work on [[Cedar]]'s Intel Omnipath network fabric. One must therefore tell <tt>starccm+</tt> to use <tt>intel</tt> as the MPI distribution. This is done with the options <tt>-mpi intel</tt>.  
Select one of the available modules:
* <tt>starccm</tt> for the double-precision flavour,  
* <tt>starccm-mixed</tt> for the mixed precision flavour.


Moreover, since neither IBM Platform MPI nor Intel MPI are tightly coupled with our scheduler, you must tell <tt>starccm+</tt> what hosts to use by means of a file containing the list of hosts. To produce that file, we provide a script called <tt>slurm_hl2hl.py</tt> which, when called with the option <tt>--format STAR-CCM+</tt>, will output the list of hosts. 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 the options <tt>--ntasks-per-node=1</tt> and <tt>--cpus-per-task=32</tt> for your job submission.

Finally, you will need to setup your job environment to use your license. If you are using Adapco's online "pay-on-usage" server, it is rather simple to configure. If you are using an internal license server, please [mailto:support@computecanada.ca contact us] so that we can help you setup the access to it.

When all is done, your submit script should look like this (this example uses 2 nodes for 1 hour, adjust these numbers based on the needs of your job):
