SCC Modules (scc-lmod)

The default and only software stack on the SCC. This stack uses Lmod as its module system. For the purposes of setting the desired software stack (see Software Stacks), its short name is scc-lmod. You can learn more about how to use the module system at Module Basics.

To see the available software, run

module avail

The modules for this stack are built for several combinations of CPU architecture and connection fabric to support the various kinds of nodes in the cluster. The right module for the node is automatically selected during module load.

More information on this software stack can be found at GWDG Docs.

Adding Your Own Modules

See Using Your Own Module Files.

Spack

Spack is provided as the spack-user module to help build your own software.

Revisions

Several versions of the module system are provided, called revisions, so it is possible to use modules as they were in the past for compatibility.

module load rev/VERSION

where VERSION is the module revision version to use. For the revisions, VERSION takes the format YY.MM representing the year (last two digits) and month the revision was made.

To see the available revisions, run the command module avail rev like

gwdu101:23 08:20:08 ~ > module avail rev

------------------------- Previous Software Revisions --------------------------
   rev/11.06    rev/20.12    rev/21.12    rev/23.12 (D)

-------------------------------- BIOINFORMATICS --------------------------------
   revbayes/1.0.11

  Where:
   D:  Default Module

Module defaults are chosen based on Find First Rules due to Name/Version/Version modules found in the module tree.
See https://lmod.readthedocs.io/en/latest/060_locating.html for details.

If the avail list is too long consider trying:

"module --default avail" or "ml -d av" to just list the default modules.
"module overview" or "ml ov" to display the number of modules for each name.

Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules matching
any of the "keys".

and you can see which revisions are available, as well as another module whose name begins with “rev”.
