JUPITER Exascale Supercomputer Live: Europe's First 1-Exaflop System Breaks 50-Qubit Quantum Record

<cite index="31-1">JUPITER, Europe's first exascale supercomputer at Germany's Forschungszentrum Jülich, runs on NVIDIA Grace Hopper Superchips and NVIDIA Quantum-X800 InfiniBand networking</cite> and achieved operational status in June 2025. <cite index="32-2">The system is capable of running 1 quintillion FP64 operations per second and is on track to be Europe's first exascale supercomputer, delivering a more than 2x speedup for high-performance computing and AI workloads compared with the next-fastest system</cite>. <cite index="38-1">JUPITER's primary Booster module is equipped with approximately 24,000 NVIDIA GH200 Grace Hopper Superchips, optimized for highly parallel workloads, with a power draw of 11 megawatts</cite>.

<cite index="38-1">JUPYTER is the most energy-efficient of the world's top five fastest systems on the Green500 list</cite>, thanks to liquid cooling and waste-heat recovery that warms buildings on campus. <cite index="31-2">Four flagship projects demonstrate scope: mapping the human brain at cellular scale via the Jülich Brain Atlas foundation model (trained in under five days on 4,096 Grace Hopper Superchips using 6.5 petabytes of brain imaging data), simulating Earth's climate at 1-kilometer resolution with full ocean-atmosphere-land coupling, developing AI for 5G/6G via collaboration with Ericsson, and quantum simulation</cite>.

<cite index="37-1">Researchers at the Jülich Supercomputing Centre and NVIDIA achieved a major milestone in quantum computing by fully simulating a universal quantum computer with 50 qubits for the first time</cite>, surpassing the previous 48-qubit record. <cite index="38-2">JUPITER was a collaborative investment by the European Union and Germany at a total cost of $587 million (€500 million), designed to close the technology gap with the United States and China in AI, climate science, and fundamental research</cite>. <cite index="43-2">With this latest system, access is being granted through the Jupiter Research and Early Access Program (JUREAP) to over 100 national and international applications</cite>.
