Setting and maintaining your environment while running a large number of diverse software applications with different requirements can be a daunting task. The Research Computing is adopting the modules system developed by Robert McLay at the Texas Advanced Computing Center (TACC) in order to ease the complexity of this process and relieve users of this burden.
See Modules Basic Usage for a short practical introduction to using modules.
You can write and use your own modulefiles. The procedure for making them available is very simple. For example, if you'd like to create version 1.0 of the module 'mymod' pick any directory you own, say ~/modules:
- Create a personal module directory
- Add a 'mymod' module directory
- Add a modulefile
Note that you can copy any environment module we have in /apps/lmod/modulefiles to serve as a starting point for your 'mymod/1.0.lua' module. To test/use the new module:
- Run the following command or add it to your ~/.bashrc file
module use ~/modules
The "myapp/1.0" module should be available for your use.
To request help with using modules or installation of new module enabled application please file a support request.

There is a well-written article on Lmod in the HPC Admin Magazine.
