JUPITER is Europe’s first exascale-class supercomputer, installed in a modular data center complex at Forschungszentrum Jülich and procured by the EuroHPC Joint Undertaking. Eviden delivered the system with NVIDIA accelerated computing, while Forschungszentrum Jülich hosts and operates it for European scientific research. The modular infrastructure incorporates warm-water cooling and heat-reuse design.
