CFD Online Discussion Forums - Using Microsoft HPC Pack with Star-CCM+

Good morning all,

We're trying to submit a job to Microsoft HPC Pack 2019 Cluster Job Scheduler.

The tickbox in gui that says "Submit Using Microsoft Job Scheduler" adds -ccs to the command which errors out with:

Code:

Unrecognized argument : -ccs

When trying to start using the -msjob command line argument instead the job is successfully submit to the job scheduler and started, however errors out with the following message for every core:

Code:

MPItrampoline: ERROR: The environment variable MPITRAMPOLINE_LIB is not set.

MPI functions are not available.

Set MPITRAMPOLINE_LIB to point to a wrapped MPI library.

See <https://github.com/eschnett/MPItrampoline> for details.

I am unsure what to set here - has any of you run into this before? The only examples I have found for MPITRAMPOLINE_LIB environment variables on the internet was Linux based and not for Windows. Unfortunately my local support don't have experience in Microsoft HPC Cluster yet so they can't really help.

I can start a job on a single node with 40 cores when specifying "Intel MPI" however the moment that I try to use 2 or more nodes, this doesn't work most likely because Microsoft HPC uses MSMPI and not Intel

The command I am using to start up is:

Code:

\\SCCM\Siemens\19.02.009\STAR-CCM+19.02.009\star\lib\win64\clang15.0vc14.2\lib\starccm+.exe -msjob -server -np 640 -power -podkey blahblah -licpath blahblah

Has anyone used Star-CCM+ on Microsoft HPC Job scheduler before and can perhaps make some suggestions?

Thank you very much in advance.
