Contemporary scientific research requires high-performance computing, the collection, storage, and processing of large amounts of data, parallel computing, and solutions in the field of artificial intelligence. To meet these demands, the EuroHPC Joint Undertaking (EuroHPC JU) was established in 2017 – a legal and financial structure that unites 33 European countries (members of the European Union and associated countries). The project’s goal is to acquire, build, and launch a European exascale-class supercomputer system for large-scale computing. EuroHPC JU aims to create infrastructure, including two pre-exascale systems (capable of performing 10¹⁷ calculations per second) and at least two petascale systems (capable of performing 10¹⁵ calculations per second), and by 2023, at least one exascale system (capable of performing 10¹⁸ calculations per second) based on European technology. In collaboration with the PRACE initiative and the GÉANT programme, EuroHPC JU ensures access to supercomputers and their associated applications for users from academic environments, research institutes, industry, small and medium-sized enterprises, and the public sector. However, the creation of tools is not the only focus. Another dimension of the Euro HPC JU involves activities related to training and informational efforts (see: EuroCC).
