Europe’s first exascale supercomputer — running on NVIDIA Grace Hopper Superchips — is mapping the brain, modeling climate, advancing 6G AI and breaking records in quantum computing simulation.
JUPITER, Europe’s first exascale supercomputer at Germany’s Forschungszentrum Jülich, runs on NVIDIA Grace Hopper Superchips and NVIDIA Quantum-X800 InfiniBand networking — and it’s had a busy year.
As the international supercomputing community gathers at ISC in Hamburg this week, four projects running on JUPITER point to what exascale computing can actually do: map the human brain at cellular scale, simulate the entire Earth’s climate at 1-kilometer resolution, build AI systems for the next generation of wireless networks and simulate a universal 50-qubit quantum computer.
“With JUPITER, Europe doesn’t just join the exascale era — it leads it, across the widest range of science and AI of any system worldwide,” said Thomas Lippert, director of the Jülich Supercomputing Centre and professor at Goethe University Frankfurt.
Four projects, detailed below, share a throughline: scientific problems that were out of reach on previous hardware are now tractable at exascale.
The Jülich Brain Atlas project — anchored at Jülich’s Institute of Neuroscience and Medicine with partner Helmholtz AI, partner hospital and other Helmholtz institutions — has produced CytoNet, a foundation model for brain microarchitecture analysis.
The complexity of the human brain is astonishing. With 86 billion neurons and about 100 trillion connections between them, understanding brain function at single neuron resolution has been out of reach, until now.
