On VSC-4 and VSC-5, use 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

1. <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.
   
2. 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.
