JUPITER, Europe’s most advanced supercomputer, has officially been declared the continent’s fastest, according to NVIDIA. Powered by the NVIDIA Grace Hopper™ platform, JUPITER marks a major milestone in scientific computing, offering over twice the speed of its nearest competitor for AI and high-performance computing (HPC) workloads.
The system is hosted at the Jülich Supercomputing Centre in Germany and owned by the EuroHPC Joint Undertaking. JUPITER’s computational power is already transforming key sectors such as climate science, quantum computing, and biomedical research.
NVIDIA announces JUPITER as Europe’s fastest supercomputer.
Built with nearly 24,000 NVIDIA GH200 Grace Hopper Superchips.
Delivers more than 2x the speed of the next-fastest European system.
Expected to exceed 90 exaflops of AI performance.
Most energy-efficient in TOP500, achieving 60 gigaflops per watt.
Designed for climate modeling, quantum research, and drug discovery.
JUPITER is on track to become Europe’s first exascale system, soon capable of performing 1 quintillion FP64 operations per second. The system dramatically accelerates AI model training, simulation, and inference, playing a vital role in foundational research across fields like structural biology, energy systems, astrophysics, and engineering.
JUPITER’s architecture is built on Eviden’s BullSequana XH3000 liquid-cooled design and is tightly integrated with NVIDIA’s Quantum-2 InfiniBand networking platform. This enables high-bandwidth, low-latency communication across nearly 24,000 NVIDIA Grace Hopper Superchips.
Not only does JUPITER rank among the top five systems on the TOP500 list, but it also stands out as the most energy-efficient — achieving 60 gigaflops per watt. This exceptional performance per watt is a result of NVIDIA’s optimized software stack and energy-conscious hardware architecture.
Early benchmarking with the Linpack suite confirms its position as Europe’s top performer in both speed and efficiency.
JUPITER is engineered to power innovation at scale. “AI will supercharge scientific discovery and industrial innovation," said Jensen Huang, founder and CEO of NVIDIA. “In partnership with Jülich and Eviden, we’re building Europe’s most advanced AI supercomputer.”
The system is expected to serve researchers across Europe with resources to address grand-scale scientific problems. Anders Jensen of the EuroHPC Joint Undertaking highlighted JUPITER’s role in ensuring technological sovereignty, while Thomas Lippert of the Jülich Supercomputing Centre emphasized its foundational impact on future research.
Kristel Michielsen noted its pivotal contribution to hybrid quantum computing, supported by NVIDIA’s CUDA-Q and cuQuantum toolkits.
JUPITER leverages NVIDIA’s full software ecosystem, enabling groundbreaking work in:
Climate Modeling: Through the NVIDIA Earth-2 platform, researchers can run high-resolution, real-time environmental simulations.
Quantum Computing: Advanced quantum research is powered by CUDA-Q and cuQuantum.
Engineering Simulation: With PhysicsNeMo, CUDA-X, and Omniverse, JUPITER facilitates AI-assisted design and manufacturing.
Drug Discovery: BioNeMo accelerates biomolecular simulations for faster pharmaceutical innovation.
Applications for access are now open to researchers across Germany and Europe, promising unprecedented computing power for public and private institutions alike.
