The mission of EuroCC 2 is to continue the establishment of a network of National Centres of Competence (NCC) in the most efficient way, while continuing to address the differences in the maturity of HPC deployment in Europe, for which improvement has already been noted. Therefore, in addition to high-level management to monitor progress in the NCCs? development, the main task of the overall activity is to support national centres in setting up their individual operational frameworks, while accessing and making the most of the experience and expertise currently available at national and European level. To support this, EuroCC 2 will work closely with a coordination and support action to be funded under DIGITAL-EUROHPC-JU-2022-NCC-01-02. A core team of EuroCC 2 applicants will also participate in the adapted continuation of the CASTIEL CSA (CASTIEL 2), which will be tailored to the needs of the EuroCC (2) NCCs and this time will also involve the Centres of Excellence. Our main goal is to drive collaboration, exchange of best practices and knowledge at the European level and to accelerate the improvement of national and thus European capabilities.
