Environment setting

The default development environment (Intel + IMPI) is set at login. Changing the used compiler and linking the library are done by loading the necessary modules.

% module list

2. Check available modules

% module avail

3. Load/unload modules

 % module load/unload  <module name>

4. Replacing modules

 % module swap  <module name before>  <module name after>
