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.
