Eamonn has installed WPS and WRF as modules:
WPS/3.6.1
WRF/3.6.1
module load WPS
module load WRF
He has also put the geog data in a central location:
/gaia/software/src/WPS_geog
To specify the number of cores for WRF:
export OMP_NUM_THREADS=9
The just run wrf.exe
I found a post that suggests the domain be decomposed into squares of no less than 15*15. I don't know if this relates to MPI or OpenMP, but I'll use it as a guideline anyway.
