===== Modules =====

On VSC-4 and VSC-5, use [[doku:spack|SPACK]] to find and load modules for most software packages.

====

  * ''module avail''     lists the **available** Application-Software, Compilers, Parallel-Environment, and Libraries 
  * ''module list''      shows currently loaded package of your session
  * ''module unload <xyz>'' unload a particular package <xyz> from your session
  * ''module load <xyz>'' load a particular package <xyz> into your session
  * ''module display <xyz>'' OR ''module show <xyz>'' show module details such as the full  path  of  the module file and all (or most) of the environment changes the modulefile will make if loaded
  * ''module purge'' unloads all loaded modulefiles
== Note: ==

  - **<xyz>** format corresponds exactly to the output of ''module avail''. Thus, in order to load or unload a selected module, copy and paste exactly the name listed by ''module avail''.\\ 
  - a list of ''module load/unload'' directives may also be included in the top part of a job submission script\\ 

When all required/intended modules have been loaded, user packages may be compiled as usual.
