WRF

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. - Homepage: http://www.wrf-model.org

Access

WRF is open to all HPRC users.

To see all versions of WRF available on Ada:

 module spider WRF

Loading the WRF module will also load all other modules necessary to run WRF. To load the default WRF module on Ada:

 module load WRF

To load a particular version of WRF on Ada (Example: 3.8.0):

 module load WRF/3.8.0-intel-2016a-dmpar

Usage on the Login Nodes

Please limit interactive processing to short, non-intensive usage. Use non-interactive batch jobs for resource-intensive and/or multiple-core processing.

Instructions for login-node usage may be derived from other sections on this page.

You are expected to be responsible and courteous to other users when using software on the login nodes.

Usage on the Compute Nodes

Non-interactive batch jobs on the compute nodes allows for resource-demanding processing. Non-interactive jobs have higher limits on the number of cores, amount of memory, and runtime length.

For instructions on how to create and submit a batch job, please see the appropriate wiki page for each respective cluster:

Ada Example

#BSUB -J wrftest          # sets the job name to myjob1.
#BSUB -L /bin/bash        # uses the bash login shell to initialize the job's execution environment.
#BSUB -W 10:00            # sets to 10 hours the job's runtime wall-clock limit.
#BSUB -n 40               # assigns 40 cores for execution.
#BSUB -R "span[ptile=20]"   # assigns 20 cores per node.
#BSUB -R "rusage[mem=2700]" # reserves 2700MB per process/CPU for the job
#BSUB -M 2700               # sets to 2,700MB the per process enforceable memory limit.
#BSUB -o wrf.%J             # directs the job's standard output to wrf.jobid

# Load the modules
module load WRF/3.8.0-intel-2016a-dmpar

# Use mpirun to start wrf
mpirun wrf.exe
