EuroHPC User Days 2025

The third edition of the EuroHPC User Days will take place in Copenhagen (Denmark) on 30 September to 1 October 2025. 

The event is organised by the EuroHPC Joint Undertaking, the EuroCC Denmark and the Danish e-Infrastructure Consortium.

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.  

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 2025 Book of Proceedings.

The manuscripts can be submitted here until 30 April, 2025. Templates for the submission of papers can be found on the dedicated page.
