Prerequisites
The OpenIFS code requires some software to be available:
grib-api (latest release) - this is available from the ECMWF software page.
lapack & blas libraries - these are usually available on all flavours of Linux/Unix. Some systems, notably HPC installations will have special optimized versions of these libraries. These should be used instead (if a version exists for your choice of compiler) to achieve a better performance. You may need to modify the compile configuration to access these optimized libraries.
