EuroCC 3 is the third phase of the European initiative aimed at consolidating the network of National Competence Centres for High-Performance Computing — the NCCs — and broadening the uptake of advanced computing technologies across Europe.

The project runs from 1 April 2026 to 31 March 2029, building on the work carried out under EuroCC and EuroCC 2. The network currently brings together 36 European and associated countries, each represented by a National Competence Centre acting as a point of contact for users of High-Performance Computing (HPC), High-Performance Data Analytics (HPDA) and Artificial Intelligence (AI).

The NCCs support companies, scientific and academic institutions, public administrations and other organisations in accessing expertise, training, specialised services, and national and European resources. EuroCC 3 places particular emphasis on small and medium-sized enterprises and industry, promoting the adoption of advanced computing through tailored support, skills development and connections to the most suitable infrastructures.

In addition to strengthening the existing centres, EuroCC 3 will establish three new NCCs, extending the network’s coverage and supporting capacity building in new regions.

The project is coordinated by the High-Performance Computing Center Stuttgart (HLRS) at the University of Stuttgart and is implemented in close cooperation with CASTIEL 3, which supports network coordination, knowledge exchange and collaboration with other European initiatives in HPC and Artificial Intelligence.

EuroCC 3 and CASTIEL 3 contribute to a more integrated European presence through the HPC in Europe Portal and the HPC Service Hub, which bring together information on centres, services, expertise, training and opportunities available across the European advanced computing ecosystem.

By developing digital skills, supporting innovation and facilitating access to computing resources, EuroCC 3 contributes to the EuroHPC Joint Undertaking’s “Widening Usage and Skills” pillar and to Europe’s goals for competitiveness, technological sovereignty and digital transformation.

EuroCC 3 has received funding from the European High-Performance Computing Joint Undertaking (EuroHPC JU) under Grant Agreement No. 101306701. The EuroHPC JU receives support from the European Union’s Digital Europe Programme and the participating countries.
