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
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 in your own home before sharing.
Complete documentation is available. Quite a lot to swallow all at once.
