Setting and maintaining your environment while running a large number of diverse software applications with different requirements can be a daunting task. The UF HPC Center 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.
Please see Modules Basic Usage for a practical introduction to using modules at the UF HPC Center.
You can write and use your own modulefiles. The procedure for making them available is very simple. Load the "personal" module to have a $HOME/.modules directory automatically created and the environment set up for using it to house your personal modulefile sub-directories. For example, once the personal module is loaded you can create a myapp sub-directory under $HOME/.modules and put a modulefile named version.lua like 1.0.lua for instance into that directory to make the "myapp/1.0" module available.
Mpi-selector Command Deprecated
With the introduction of modules, mpi-selector has been deprecated. If you have been using mpi-selector to set up your MPI environment, please see From mpi-selector to environment modules for more information.
