The EuroCC National EuroHPC Competence Center Sweden (ENCCS) is a joint initiative between the ten main Swedish research universities and RISE Research Institutes of Sweden. The center is hosted by Uppsala University (UU) on behalf of the consortium and will include the relevant competences at the other nodes. The initiative is funded by the EuroHPC JU, Swedish Research Council (Vetenskapsrådet) and the Swedish Innovation Agency (Vinnova). It is designed to prioritize support based on: - Needs of academic users with large scale allocations such as PRACE allocations in EU and SNIC allocations in Sweden - The current industrial usage of HPC and their future HPC and Artificial Intelligence (AI) needs - Needs for training and support to enable a wide range of Swedish users to use the new hardware deployed in pre-exascale systems, in particular Euro HPC JU (pre)exa-scale system LUMI The vision of the ENCCS is to establish an HPC Competence Centre as a single reference and contact point for academia, industry and public administration. All activities are focused and orchestrated as a single know-how hub both for academia and industry.
