Jupiter is an exascale supercomputer hosted at Forschungszentrum Jülich in North Rhine-Westphalia, Germany. Developed by the Jülich Supercomputing Centre (JSC) and owned by the European High-Performance Computing Joint Undertaking (EuroHPC JU), Jupiter became operational in June 2025. It is based on a modular architecture featuring NVIDIA GH200 Grace Hopper Superchips and is recognized as Europe's fastest supercomputer, ranking 4th on the November 2025 TOP500 list of the world’s fastest supercomputers. Jupiter is also the most energy-efficient system among the top five.
