What happened? What did you expect to happen?

I'm running default collection with 6 cores 1 node GCHP simulation and crashed immediately.
Failed run output:

What are the steps to reproduce the bug?

The content and location of the error message are exactly the same as those in #8 and #443 (comment) . I followed the suggestion in the tickeyts and re-install and compile ESMF package and make sure ESMF_COMM points to openmpi instead of mpiuni. However, the error persists.

Any insights or comments would be greatly appreciated. Thank you so much for you help and time!

Best,
Xinying

Hi @Xinying331, the model is crashing at this section of MAPL based on the traceback message with filename and line number:

    call ESMF_VMGet(cap%vm, petcount=npes, mpicommunicator=comm, rc=status)
    _VERIFY(status)
     _ASSERT(CoresPerNode <= npes, 'something impossible happened')

One option is to print CoresPerNode and npes at this point in the code, right before the _Assert call. Before doing that check what you put for CoresPerNode in setCommonRunSettings.sh and compare against your run script. Make sure they are consistent. Also check to see if there are any messages in log file allPEs.log.
