Old Module System¶

The old module system used module files stored under:

/home/software/tools/modulefiles

Many older packages in this system may no longer work. Prefer the current module system described in Environment Setup.

Identifying old modules¶

When you run module avail, the old modules appear under a heading similar to:

-------------------------- /home/software/tools/modulefiles --------------------------

Older module names are often lower case, such as python, r, and openmpi, while current modules commonly use names such as Python, R, and OpenMPI.

Accounts created before March 2022¶

Accounts created before March 2022 may not automatically load the current module system. To enable it alongside the old system, add the following line to your .bashrc file. Users of zsh can make the equivalent change in .zshrc.

First back up and edit your .bashrc:

cd ~
cp .bashrc .bashrc_backup
nano .bashrc

Find the line:

module use -a /home/software/tools/modulefiles

Add this line after it:

module use /home/software/tools/eb_modulefiles/all/Core

Log out and back in, then test the current module system:

module load foss/2020a

If you need to restore the previous configuration:

cp .bashrc_backup .bashrc
