WPS
Overview
WPS is the preprocessing system for the Weather Research and Forecasting Model (WRF).
Version 4.0.3 is installed on the CSF.
Restrictions on use
WRF is open source, and has been released with no restrictions on use (licensing or otherwise).
Set up procedure
We now recommend loading modulefiles within your jobscript so that you have a full record of how the job was run. See the example jobscript below for how to do this.
Load one of the following modulefiles:
module load apps/gcc/wps/4.0.3
Copy the running directory (which contains standard input files required by WPS) for your version of the model using:
cp -a $WPS_RUNDIR [scenario_name]
Change into the new directory, and link to the geography data directory:
ln -s $WPS_GEOG geog
Running the application
Please do not run the WPS processes on the login node – they are computationally intensive, and some require MPI parallisation to run properly. Jobs should be submitted to the compute nodes via batch.
Parallel batch job submission
Three example batch scripts are included in the running directory:
batch_geogrid_par.sh batch_ungrib_serial.sh batch_metgrid_par.sh
These have the form (for parallel jobs):
#!/bin/bash --login #$ -cwd #$ -pe smp.pe 4 module load apps/gcc/wps/4.0.3 mpiexec -np 4 geogrid.exe 2>&1 | tee geogrid.log
