EESSI¶

The European Environment for Scientific Software Installations (EESSI) is a collaboration across Europe that builds and distributes a common stack of scientific software. It is designed to run efficiently on everything from laptops to large HPC clusters, and it is distributed using CernVM-FS.

Availability on HPCF

At the Cyprus Institute, the full EESSI software stack is available on all of our HPC systems. This means users can easily access hundreds of pre-built applications and libraries without needing to compile them themselves.

Public Mirror

In addition, the Cyprus Institute hosts a public Stratum-1 mirror. This service is openly available to the wider community, so anyone can use it — even on personal computers — to access the same software stack that we run on our HPC clusters.

Quickstart Installation

To try EESSI locally on your own system, follow the official Quickstart guide provided by the project: Quickstart Installation Guide

Using the Cyprus Institute’s Mirror

If you want to configure your system to use our mirror directly, you can add the following configuration file:

sudo tee /etc/cvmfs/domain.d/eessi.io.local > /dev/null <<'EOF'
CVMFS_SERVER_URL="http://eessi.hpcf.cyi.ac.cy/cvmfs/@fqrn@;$CVMFS_SERVER_URL"
CVMFS_USE_GEOAPI=no
EOF
  

Then reload CernVM-FS to apply the changes:

cvmfs_config reload -v software.eessi.io
