European Environment for Scientific Software Installations (EESSI)

Welcome to EESSI's GitHub organization! Find our offical documentation here 📜

The European Environment for Scientific Software Installations (EESSI, pronounced as "easy") is 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.

We maintain a list of systems where EESSI is available, and installing EESSI for yourself is well documented.

Here, you can contribute new software to EESSI or even contribute to the development of EESSI itself. EESSI is organized in three layers, each with a dedicated repository.

Relevant repositores:

Thanks to the MultiXscale EuroHPC Centre of Excellence we are able to provide support to the users of EESSI.

The EESSI support portal is hosted in GitLab: https://gitlab.com/eessi/support.
