HWW systems uses environment modules, a package for managing user environments. Software such as compilers, libraries, tools and some widely used application codes are available to users via modules. Thus, in order to use a particular version of a particular piece of software you must first load its module. On log-in to the system a default collection of modules are available.
- You can inspect which modules you have loaded currently by the command module list.
- In order to inspect which modules are available to use, you can issue the command module avail.
- If you want to swap one currently loaded module for another that is not, module swap PrgEnv-pgi PrgEnv-gnu for example swaps the currently loaded CRAY PGI Programming version PrgEnv-pgi for CRAY own programming version PrgEnv-cray.
