Running WRF on Derecho after default modules were changed

[abenz]

I am having issues with running WRF on Derecho. I get an error that I cannot run wrf due to an mpi library/ module loading issue. I have not changed how I run wrf, but I was informed that the modules to run wrf were changed recently on Derecho. Does anyone know what mpi modules I should be loading now? I currently use this to run wrf:
mpiexec ./wrf.exe

Thanks,

Andrea

Hi Andrea,
I'm not sure what changed recently that would be causing your issue. I'm able to run WRF on Derecho without any problems. I have the following modules loaded:

 1) ncarenv/25.10 (S)   3) intel/2025.2.1        5) libfabric/1.22.0    7) hdf5/1.14.6    9) ncview/2.1.9
  2) craype/2.7.34       4) ncarcompilers/1.1.0   6) cray-mpich/8.1.32   8) netcdf/4.9.3  10) ncl/6.6.2

If you still experience the issue after using those modules I would recommend contact CISL support, as it's a computing environment issue.
