At ISC, JUPITER Shows What Exascale Science Looks Like
NVIDIA Blog · Chris Porter · 2026-06-22
NVIDIA's Chris Porter showcases four scientific breakthroughs enabled by JUPITER, Europe's first exascale supercomputer at Forschungszentrum Jülich, including a cellular-resolution brain-mapping AI, a 1-kilometer global climate simulation winning the Gordon Bell Prize, 6G AI research with Ericsson, and a world-record 50-qubit quantum computer simulation.

Claims
- JUPITER enabled CytoNet, a foundation model for brain microarchitecture trained on 6.5 petabytes from 21 post-mortem brains using 4,096 NVIDIA Grace Hopper Superchips in under five days.
- The ICON climate model won the Gordon Bell Prize for Climate Modelling by simulating a fully coupled Earth system at 1-kilometer resolution, running 146 days of climate in 24 hours of compute on 20,480 Grace Hopper Superchips.
- Jülich Supercomputing Centre set a world record by fully simulating a universal 50-qubit quantum computer, surpassing the previous 48-qubit record by leveraging coherent CPU-GPU memory in GH200 Superchips.
- Ericsson and Forschungszentrum Jülich are collaborating on JUPITER to develop brain-inspired, energy-efficient AI architectures for 5G evolution and 6G networks.
- Exascale computing has transitioned from a research milestone into production science, making previously intractable problems across neuroscience, climate, wireless, and quantum tractable.
Key quotes
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.
For the first time, we're not just using AI to analyze the brain — we're building an agent that can think through the experiment itself. That changes what neuroscience will be, and JUPITER is what makes that sentence possible to say today.
Our simulations resolve the fine-scale winds, ocean eddies and upper-ocean mixing that shape marine ecosystems and regulate the ocean's uptake of carbon. At a global resolution of just 1 kilometer, many of these interactions emerge directly from the laws of physics rather than being approximated.
