WRF 3.7

Basic Information

Installation

This entry covers the entire process performed for the installation and configuration of WRF 3.7 on a cluster.

Usage

This section describes the method to submit jobs with the resource manager SLURM.

#. Run WRF from a SLURM bash script, for this example we will use a test case in wrf-3.7/tests/em_real

sbatch example.sh

The following code is an example for running WRF using SLURM:

example.sh
#!/bin/bash
#SBATCH --job-name=wps-wrf                      # Job name
#SBATCH --mail-type=ALL                         # Mail notification
#SBATCH --mail-user=<user>@<domain>             # User Email
#SBATCH --error=%x-%j.err                       # Stderr (%j expands to jobId)
#SBATCH --output=%x-%j.out                      # Stdout (%j expands to jobId)
#SBATCH --ntasks=2                              # Number of tasks (processes)
#SBATCH --nodes=1                               # Number of nodes
#SBATCH --time=3:00:00                          # Walltime
#SBATCH --partition=longjobs                    # Partition
