A few comments here:
- Why to use release candidate instead of a stable version?
- Which version does this correspond to? There is no tags/releases in https://github.com/VeloxChem/VeloxChem/tags.
- I'd suggest to include version in the module name too (and git hash if there is no versioning)
- I can't look into the modules as
cannot open directory '/appl/local/csc/modulefiles/veloxchem/': Permission denied

Thanks Tuomas for the detailed and extended comments! Much appreciated! I'll address these points
as follows:
- Preview disappeared: No idea why the preview is missing
- Version choice: This is the version suggested by the VeloxChem developers. I couldn’t find explicit versioning or tags in the repo, so the only reference I could use is the output from "vlx --version" .
- Module permissions: Thanks for pointing that out. Has now been fixed.

| module use /appl/local/csc/modulefiles | |
| module load Local-CSC |
(Which one is recommended?)

Didn't even know about Local-CSC. Have only seen the other version, e.g. https://docs.csc.fi/apps/lammps/#lumi-c-hybrid-mpiopenmp
| ```bash | ||
| module use /appl/local/csc/modulefiles | ||
| module load veloxchem/cpu | ||
| source $VLXHOME/vlxenv/bin/activate |

I think it'd be better to install veloxchem outside venv (and set PYTHONPATHs in module file instead). Then users have possibility to create their own venv for a few extra packages if needed. (Another question is that would a container-based installation be better?)

Regarding this I have no opinion or experience. Maybe discuss it in detail outside this PR?

Would it work to define #SBATCH --cpus-per-task=8 instead and make this block like in cpu run?

Right! That would be more consistent.

This input script could be included for testing.
