EESSI
EESSI stands for the European Environment for Scientific Software Installations - a collaboration between different European partners in HPC community.
The goal of this project is to build a common stack of scientific software installations for HPC systems and beyond, including laptops, personal workstations, and cloud infrastructure.
For more information, see the official EESSI documentation.
EESSI on IT4I
The EESSI project is available on login, cn, and acn nodes on both Barbora and Karolina.
To use the EESSI software installations, load the environment using the command:
source /cvmfs/software.eessi.io/versions/2025.06/init/bashYou can then use the ml av command to see the list of all EESSI and IT4I modules. EESSI modules will be listed first:
{EESSI 2025.06} $ ml av
