Description
From the WRF homepage: The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. WRF is suitable for a broad spectrum of applications across scales ranging from meters to thousands of kilometers.

Modules
WRF requires the following module file to run:
apps/wrf/3.3
- See Modules for more information.
Running WRF on CIRCE
The WRF user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.
- Note on CIRCE: Make sure to run your jobs from your $WORK directory!
- Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.
If, for example, you have your WRF input files located in your job directory, you would set up a submit script like this:
- The script below (for testing, name it “wrf-test.sh”) can be copied into your job directory (the folder with your input files) and modified so that you can submit batch processes to the queue. For help on submitting jobs to the queue, see our SLURM User’s Guide. Scripts are provided as examples only. Your SLURM executables, tools, and options will vary.
#!/bin/bash # #SBATCH --comment=wrf-test #SBATCH --ntasks=8 #SBATCH --job-name=wrf-test #SBATCH --output=output.%j.wrf-test #SBATCH --time=01:00:00 #### SLURM 8 processor WRF test to run for 1 hour. module load apps/wrf/3.3 module load compilers/intel/11.1.064 mpi/mvapich2/1.6 module load apps/netcdf/4.0.1 export WRFIO_NCD_LARGE_FILE_SUPPORT=1 mpirun wrf.exe
Next, you can change to your job’s directory, and run the sbatch command to submit the job:
[user@login0 ~]$ cd my/jobdir [user@login0 jobdir]$ sbatch ./wrf-test.sh
- You can view the status of your job with the “squeue -u <username>” command
