Model code
OpenIFS models are predominantly Fortran code and a small amount of C. They require some flavour of Unix (such as Linux) and known to run on a number of systems, some of which are directly supported by ECMWF. OpenIFS models work on laptops, desktops, Linux clusters and large HPC systems. The maximum resolution possible on each platform is limited mainly by available memory (RAM) and processor speed.
The following table details what combinations have been tested and the technical support level. For scientific support, see the OpenIFS documentation provided on this website or email openifs-support@ecmwf.int.
See Release Notes for more details on compilers and libraries tested with OpenIFS versions. Please see the Prerequisites page for details of what software is required to be able to run OpenIFS models.
