+Some conda packages available on `conda-forge` and `bioconda` support MPI (via `openmpi` or `mpich`). However, just using the `openmpi` and `mpich` packages from `conda-forge` often does not work on HPC systems. More information about this can be found [here](https://conda-forge.org/docs/user/tipsandtricks.html#using-external-message-passing-interface-mpi-libraries).
In order to be able to correctly use these MPI packages with the MPI libraries installed on our clusters, two steps need to be performed.

These "dummy" packages are empty, but allow the solver to create correct environments and use the system-wide modules when the environment is activated.
Secondly, when activating the conda environment and using the package, the system-wide `openmpi/4.1` or `mpich/4.0` module needs to be loaded depending on the MPI library used.
