To make it easily for you to select and switch between different software packages, ‘modules’ (modules.sourceforge.net) has been installed. It helps you to solve the conflicts while switching between software packages. It allows user to load the necessary configurations for different programs and versions easily, and unload them later if necessary.
In order to manipulate the modules, you can issue the following commands after you login.
|module avail||show available modules.|
|module whatis||show all available modules with its description.|
|module list||show which modules are currently loaded.|
|module load pkg||load the module named pkg.|
|module load pkg/version||load a specific version of the module named pkg|
|module unload pkg||remove the module named pkg.|
|module help pkg/version||show a detailed description for a specific version of module named pkg.|
|module show pkg||show what environment variables of module named pkg actually are set or modified.|
