Worked Example: We explain the model installation and the process of running of a forecast experiment on the ECMWF Atos Sequana XH2000 HPC facility (hpc2020).
It is important to note that the installation process on hpc2020 will not directly translate to alternative systems. To address this we present details about a docker install in the last section of this guide. |
Access requirements
OpenIFS is licensed software and using the model requires your affiliation with an institute which has signed the ECMWF OpenIFS software licence agreement. In order to access the model sources and other required data packages, you need to have a peronsal ECMWF account which you can create on the ECMWF web site or by clicking here. If you are a new model user you should contact OpenIFS support by emailing openifs-support@ecmwf.int, stating your full name, your affiliation and related email address, and your ECMWF account user name. OpenIFS staff will then activate OpenIFS user policies for your personal ECMWF account.
Extract the OpenIFS package
Create your local installation of OpenIFS 48R1.1 by downloading and extracting the tarball containing the model source package. The tarball can be downloaded from this web site: https://sites.ecmwf.int/openifs/openifs-data/src/48r1/openifs-48r1.tar.gz. Please note that access to this web site is restricted to registered OpenIFS users with valid ECMWF login credentials.
