The third EuroHPC User Days took place in Copenhagen at the Royal Danish Library's Cultural Centre, in the Black Diamond building & at the Danish Architecture Center. It brought together more than 300 participants over two days. The event was organised by the EuroHPC Joint Undertaking and the Danish e-Infrastructure Consortium.
Attendees showcased EuroHPC projects that have used European HPC supercomputing resources and AI Factories, shared best practices in the development of these projects, gathered feedback from EuroHPC users and engaged with potential new users.
The event provided also the opportunity to supercomputing users in Europe to explore various topics and enhance their understanding of the opportunities provided by the EuroHPC Joint Undertaking and the support available to users.
