We describe the process how to build the model from sources and carry out a few basic tests, how to run an example forecast experiment, for which initial experiment data is made available, and how to visualise the model output by creating plots.

In this version of the quickstart guide, it is assumed that the user has access to the ECMWF Atos HPC (hpc2020). This is however not a requirement and the description is kept as generic as possible and applies to different hardware platforms in the same way.

Info

We explain the model installation and the running of a forecast experiment as it can be done on the ECMWF HPC facility (hpc2020 Atos). 

All data files and configuration scripts that are required for the worked example experiment

Info

All data files for the example experiment and any additional scripts can be found on the ECMWF HPC file system here:  /perm/openifs/oifs_data/48r1/example

The model will be installed into $HOME/openifs/openifs_48R1.0/

The example forecast experiment will be set up in directory $PERM/i4xc/
