Upcoming modulesystem change alert!

Due to large number of applications and their versions it is not practical to keep them explicitly listed at our wiki pages. Therefore an upgrade of modulefiles is underway. A feature of this upgrade will be the existence of default module for every application. This default choice does not need version number and it will load some (usually latest) version.

You can test the new version now by adding a line

source /cvmfs/

to your script before loading a module. Then, you can list all versions of parallel and load default version of parallel as

module avail parallel/ # list available modules
module load parallel   # load (default) module

If you wish to keep up to the current system, it is still possible. Simply list all modules by

module avail parallel

and choose explicit version you want to use.
