O JUPITER tops the Green500 list as the world's most energy-efficient system. This is achieved through cooling and energy reuse, running entirely on renewable energy.
Commissioner Ekaterina Zaharieva said at the inauguration: "With Europe's first exascale supercomputer, we open a new chapter for science, AI, and innovation. JUPITER strengthens Europe's digital sovereignty, accelerates discovery, and ensures that the most powerful and sustainable computing capacity is available to our researchers, innovators, and industry."
JUPITER, located at the Forschungszentrum Jülich in Germany, fundamentally changes the playing field. The system performs over a trillion operations per second, comparable to the computing power of a million smartphones combined. This positions Europe at the forefront of supercomputing, with the fourth-fastest system globally.

JUPITER allows scientists to run climate and weather models with kilometer-level accuracy. This means much more accurate predictions of extreme events like heat waves, severe storms, and floods. For policymakers and emergency planners, this means better preparedness.
The supercomputer also supports the development of AI solutions. The system will power the AI Factory (JAIF), announced in March 2025, to train advanced language models for generative AI and next-generation digital technologies.
JUPITER is part of Europe's plan for a network of AI Gigafactories. These large-scale, energy-efficient computing centers will focus on training and deploying cutting-edge AI models.
