Work in progress
(30 April 2025)
The contents of this tutorial are currently being reworked to be up-to-date with recent developments in CernVM-FS, and to be well integrated in the EESSI documentation.
It is based on the "Best Practices for CernVM-FS in HPC" tutorial that was held on 4 Dec 2023, see also https://multixscale.github.io/cvmfs-tutorial-hpc-best-practices.
What is EESSI?¶
The European Environment for Scientific Software Installations (EESSI, pronounced as "easy") is a collaboration between different European partners in the HPC (High Performance Computing) community.

EESSI provides a common stack of optimized scientific software installations that work on any Linux distribution,
and currently supports both x86_64
(AMD/Intel) and aarch64
(Arm 64-bit) systems, which is distributed
via CernVM-FS.
