Obtaining the OpenIFS package
Create your local installation of OpenIFS 48R1.0 by cloning or branching from the git repository with the OpenIFS package. The location will be your new OIFS_HOME place.
You will need approximately 4 GB of disk space for the model sources, the bundle packages, and the built model binaries.
git clone ssh://git@git.ecmwf.int/~daha/openifs-main-git.git
Please note that currently access to this repository is restricted to a limited number of users.
Build OpenIFS
The $OIFS_HOME/bin/openifs-test.sh script can be used to build the model and run initial tests.
Edit the script and in line 16 set the location of your OIFS_HOME directory which is the location where you have extracted the git repository and where this script should be located.
The usage of the script is shown with the command: openifs-test.sh -h
The option -e defines the compiler environment (intel or gnu). The default is intel.
Run the build process and the tests using the following command:
cd $OIFS_HOME ./bin/openifs-test.sh -cbt
Note: It is normal to see warnings during the build process.
This will build the model binaries for the selected compiler and will run the ifs-test t21 and t42 tests.
