EESSI hackathon (25 Sept. 2026, Dublin)

On Friday 25 September 2026 (09:30-16:30 local time, UTC+1), an EESSI hackathon will be organised in the wake of the EuroHPC User Days which takes place 22-24 September 2026 in Dublin.

Provided by EuroHPC CoE MultiXscale in collaboration with the EuroHPC Federation Platform

Tip

This is primarily an in-person event, with space for about 25 on-site participants.

Attending the sessions is free, but you must be registered to attend in person or to join the Zoom webinar session for online participation!

See also Registration.

The hackathon will be general in nature, but centred primarily on the needs of in-person participants. A detailed program will be added after initial registrations have taken place and discussions with those registrants.

An expected general outline of the program is:

  • What is EESSI?
  • How do I build my own software on top?
  • How do I tweak EESSI for my site?
  • How do I contribute to it?

Ample time will be provided for participants to follow prepared examples (where they are feasible).

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.

Preparatory Material

While most of the content will be introduced on the day, it is likely very beneficial to follow some topics from the recent EESSI webinar series relevant to the hackathon:

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 #hackathon 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.
