===== Modules =====

Modules are a simple mean to update your environment variables to support different runtimes.

Whatever you can do with modules you can do with a shell script. But they're way more convenient!

==== Using ====

Default modules (and shared modules created by other users) are available under ''/home/modules''.

To load a module you use a command like:
  module load mpi/openmpi/4.1.4

The last argument is actually the path of the module file from /home/modules .

=== Easiser access to scripts ===

To include ''/home/software/utils'' in your $PATH, you can now use
  module load utils/utils

=== Own modules ===

To use modules in your own home dir you can
  mkdir $HOME/modules
  module load utils/ownmods
then you'll be able to load modules from $HOME/modules.

==== Creating ====

FIXME TODO

The easiest way to create a module is to copy an existing one and update it to suit your needs. Better to test changes [[#own modules|in your own home]] before sharing.

[[https://modules.readthedocs.io/en/latest/modulefile.html|Complete documentation]] is available. Quite a lot to swallow all at once.
