Which Compiler and MPI library should I use?

For model simulations in production mode we recommend to use Intel compilers and Open MPI:

module load intel-oneapi-compilers/2022.0.1-gcc-11.2.0
module load openmpi/4.1.2-intel-2021.5.0

Do not forget to consult the recommended environment settings and adjust your run script accordingly. Without these settings applications can run unexpectedly slowly.
