In order to use the installed software, it is necessary to configure the relating environment variables for compilers and libraries so that searching paths are correct, corresponding libraries can be linked up, license servers can be connected, etc.

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.
