EuroHPC User Days 2026

The fourth edition of the EuroHPC User Days will take place in Dublin (Ireland) in September 2026.

The final dates of the EuroHPC User Days 2026 are still to be confirmed. 

The event is organised by the EuroHPC Joint Undertaking.

Attendees will be able to showcase EuroHPC projects that have used European HPC supercomputing resources, share best practices in the development of these projects, gather feedback from EuroHPC users and engage with potential new users.   

The event will provide supercomputing users in Europe with the chance to explore various topics and enhance their understanding of the opportunities provided by the EuroHPC Joint Undertaking and the support available to users.  

Submission Instructions

Users of the EuroHPC JU systems are invited to present their work and the opportunity to submit papers setting the results of the projects that used EuroHPC resources. Papers need to show scientific excellence in the chosen thematic fields.

The submitted papers will be evaluated by a peer review committee and selected for presentation during the conference and publication in the Elsevier Procedia Computer Science of EuroHPC User Days 2026 Book of Proceedings.

Papers should acknowledge the role of the Hosting Entity and EuroHPC JU, which include the results of the work. Users shall use the following wording in such acknowledgement in all such papers and other publications: “We acknowledge EuroHPC JU for awarding the project ID EHPC-XX-XXXXXXX-XXX access to [resources on partition name hosted by site]”. 

Users can use as many instances of the pattern [resources on partition name hosted by site] as the number of systems awarded via EuroHPC JU.
