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:

• 🆕 software-layer - Go here to for the software layer, where you can contribute new software to EESSI
• ⚙️ compatibility-layer - Go here for information and changes to the compatibility layer enabled by Gentoo Prefix
• 🗂️ filesystem-layer - Go here for information and changes to the filesystem layer enabled by CernVM-FS
• 🛠️ software-layer-scripts - Go here for the tooling and scripts used to build software for the software layer
• 🤖 eessi-bot-software-layer - Go here for the code powering the EESSI Build-test-deploy bot used in all EESSI software installations
• 📚 docs - Go here to suggest changes to our documentation
• 🔍 test-suite - Go here for the EESSI ReFrame test suite.

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