Software layer

The software layer of the NESSI project uses EasyBuild, Lmod and archspec.

Accessing the software stack

You can set up your environment by sourcing the init script:

$ source /cvmfs/pilot.nessi.no/versions/2023.06/init/bash

Accessing NESSI via a container

You need Singularity version 3.7 or newer. Then, simply run

$ ./eessi_container.sh

Once you get presented the prompt Singularity> run the above source command.

If you want to build a package for the software repository, simply add the arguments --access rw, e.g., full command would be

$ ./eessi_container.sh --access rw

Note, not all features/arguments listed via ./eessi_container.sh --help are implemented.
