EasyBuild + EESSI + Spack event at CINECA

A joint EasyBuild, EESSI, and Spack tutorial + hackathon was organised in Bologna (Italy) on 19-21 May 2026. It was hosted by CINECA, who operate the Leonardo EuroHPC JU supercomputer, and was co-organised by representatives of the MaX and MultiXscale EuroHPC Centres-of-Excellence.

The event featured presentations by core developers of all three projects, and allowed attendees from CINECA, MaX, ECMWF, and the EBRAINS project to freshen up their knowledge, learn about recent developments, and gain extensive hands-on experience while having direct access to experts.

Although EasyBuild, EESSI, and Spack already have well-established communities for a long time, even over a decade for both EasyBuild and Spack, a joint event that brings together their communities like this was a first.

Slides and recordings of all presentations are available.

EUM'26 - Day 1

The 11th EasyBuild User Meeting (EUM'26) took place in the beautiful city of Guimarães, the home of the EuroHPC supercomputer Deucalion.

The EasyBuild community (and beyond) gathered again to learn more about recent developments, letting HPC sites that use EasyBuild showcase how they are doing so, attend presentations on projects (loosely) related to EasyBuild, and discuss the future of EasyBuild, including the (potential) impact of LLMs.

The event was sponsored by Centro Nacional de Computação Avançada (the Portuguese National Center for Advanced Computing), INESC TEC, Fujitsu, Do IT Now, Inuits, Microsoft Azure, and NVIDIA.

This blog post covers the first day of the 3-day event, see also day 2 and day 3.
