ARWpost

Overview

ARWpost is a post-processing tool to generate GrADS input files from WRF ARW output files.

Version 3.1 is installed on the CSF. This has been compiled specifically for the AMD Bulldozer nodes and will not run on other nodes.

Restrictions on use

There are no restrictions on accessing this software on the CSF.

Please see the WRF Public Domain Notice for further information.

Set up procedure

To access the software you must first load the modulefile:

module load apps/pgi-13.6-acml-fma4/arwpost/3.1

Running the application

Please do not run ARWpost on the login node. Jobs should be submitted to the compute nodes via batch or can be run interactively via qrsh.

Serial batch job submission

Make sure you have the modulefile loaded then create a batch submission script, for example:

#!/bin/bash
#$ -S /bin/bash
#$ -cwd             # Job will run from the current directory
#$ -V               # Job will inherit current environment settings
#$ -l bulldozer     # Job will run on an AMD Bulldozer node
#$ -l short         # Optional: assumes max 12 hour runtime
                    # There is a dedicated node for 'short jobs'

# The executable will read a file called 'namelist.ARWpost' in the current directory
ARWpost.exe 

Submit the jobscript using:

qsub scriptname

where scriptname is the name of your jobscript.

Interactive Use via qrsh

If you wish to run the command interactively on an AMD Bulldozer node you should first schedule an interactive session as follows:

qrsh -l short -l bulldozer
  #
  # Wait for a new prompt on a backend node (e.g., node201)

# We are now on the backend node...
module load apps/pgi-13.6-acml-fma4/arwpost/3.1

# Edit your namelist.ARWpost if required
gedit namelist.ARWpost

# Now run the ARWpost executable
ARWpost.exe

# When finished with the interactive session, log out of the node to free it up
exit
