This will build the model binaries for the selected compiler and will run the ifs-test t21 and t42 tests.
Platform configuration file
You will need to set up a configuration file for your OpenIFS installation. This file can be located anywhere but the recommended location would be somewhere inside your $OIFS_HOME installation.
This file sets global variables for your model installation, depending on your local system, and it will need to be sourced prior to running the model.
We provide a template file in $OIFS_HOME/bin/oifs48r1-config.sh
. You should edit this file and update variable OIFS_HOME with your installation's path.
We recommend that you include the command source $OIFS_HOME/bin/oifs48r1-config.sh
in your shell configuration files (e.g. in .bashrc).
Run a forecast experiment
Extract the example forecast experiment i4xc.tgz
into a location suitable for model experiments.
Note: The experiment directory can be a separate location from the earlier model installation path $OIFS_HOME. You will need more disk space depending on the duration of the forecast experiment.
Example: In our example on the ECMWF hpc2020 the model installation $OIFS_HOME is in $HOME/openifs
and we extract the i4xc package in $PERM, and the experiment directory shall therefore be $PERM/i4xc/2016092500
.
