On Thursday 2 October 2025, a continuous integration and continuous deployment (commonly referred to as CI/CD) hackathon will be organised in the wake of the EuroHPC User Days which takes place 30 Sept + 1 Oct 2025 in Copenhagen.

The hackathon will give a general introduction to CI/CD, and then focus on the specific issues that can affect CI/CD workflows in the HPC domain. It will introduce the European Environment for Scientific Software Installations (EESSI, https://eessi.io) and some of the tools that EESSI is creating to help to address these issues.

Ample time will be provided for participants to follow prepared examples, as well as time to investigate the implementation of some of the practices for their own application codes.

The session will be recorded. Recordings, slides, and materials used will be made publicly available shortly after the event via this page.

If you have any questions regarding this event, please send an email to support@eessi.io.

Familiarity with Git is also useful, as is some experience with building and/or installing software packages.

Q&A via Slack

For posting questions or comments during the event, we strongly prefer that you post them in the #cicd channel in the EESSI Slack (direct link to that channel).

If you haven't joined the EESSI Slack yet, first use the "Slack channel" link on the EESSI website (https://eessi.io).

There will also be an opportunity to ask questions directly to the speakers, should you wish to do so.
