Software layer

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

See also https://eessi.github.io/docs/software_layer.

Pilot software stack

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

$ source /cvmfs/pilot.eessi-hpc.org/versions/2021.12/init/bash
Found EESSI pilot repo @ /cvmfs/pilot.eessi-hpc.org/versions/2021.12!

Accessing EESSI 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.
