knows caveats

[wpoely86]

list of knows caveats with Lmod compared to environment modules setup:

• module load cluster is broken, must use module load cluster/$VSC_DEFAULT_CLUSTER_MODULE
• changes to $MODULEPATH must be done with module use
  • if not, Lmod may spit out The environment MODULEPATH has been changed in unexpected ways

bugs/issues:

• output of module list and module --terse avail doesn't go do stdout as desired
• manual module use on /apps/gent/.../modules/all results in spider cache not being found
  • /apps/gent is a symlink, which gets resolved on manual module use, leading to path mismatch (bug in Lmod?)

As long as you strictly only append or prepend to the $MODULEPATH, you could get away without use?

Off all these issues, only the second remains and is unavoidable. However, if you consistently pre- or append, you should be just fine.

@boegel: module load cluster is still broken when the cluster module is already loaded, but let's see if we need to remedy that
