The EuroHPC Joint Undertaking (EuroHPC JU) and the German-French supercomputer consortium ParTec-Eviden supercomputer consortium have signed a contract for the construction of JUPITER. JUPITER will be the first exascale supercomputer in Europe, hosted at Forschungszentrum Jülich, member of GCS, in the German state of North-Rhine Westphalia. The system, designed for large-scale simulations and artificial intelligence (AI) applications in science and industry alike, is expected to launch in 2024.
