JUPITER at Forschungszentrum Jülich in North Rhine-Westphalia, Germany, becomes the fastest #supercomputer in Europe.
JUPITER, developed by the Jülich Supercomputing Centre (JSC) and owned by EuroHPC Joint Undertaking (EuroHPC JU), ranks 4th on the June 2025 #TOP500 list of the world’s fastest supercomputers and stands as the most energy-efficient system of the top 5 of the listing, which was presented today at the International Supercomputing Conference #ISC25 in Hamburg.
JUPITER Booster, supplied by Eviden, is equipped with around 24,000 NVIDIA GH200 Grace Hopper #Superchips, which are optimized for highly parallel applications – such as training AI models or numerically demanding simulations.
This enables, for instance, the training of the largest #AI models, known as large language models (#LLM). At full capacity, JUPITER needs less than one week to complete the task.
In the future, the Booster partition will be supported by a Cluster partition, supplied by ParTec AG, featuring conventional central processing units (CPUs) with high memory bandwidth. The Cluster is specially designed for data-intensive tasks.
With its enormous computing capacity, JUPITER opens up new possibilities in a wide range of application areas. #Climate and #Weather simulations can be enhanced and will significantly improve predictions of local extreme weather events, such as heavy rain and severe thunderstorms. JUPITER will also drive the development and optimization of a #SustainableEnergy system.

JUPITER is also setting new standards in terms of energy efficiency – with more than 60 billion floating point operations per watt, JUPITER is the most efficient computer of the five fastest systems in the world.
With its highly efficient warm water-cooling system, JUPITER is also designed to use the waste heat generated in operation to heat buildings and will be integrated into the Jülich campus heating network.

JUPITER Booster and its storage systems have been fully installed. Scientific users will get access in the coming weeks. Over 100 national and international applications have been selected via the JUPITER Research and Early Access Program (JUREAP), the GCS Exascale Pioneer Call, and the Gauss AI Compute Competition for AI projects.

JUPITER, short for “Joint Undertaking Pioneer for Innovative and Transformative Exascale Research”, is funded half by the European High Performance Computing Joint Undertaking (EuroHPC JU) and a quarter each by the Bundesministerium für Forschung, Technologie und Raumfahrt (BMFTR, formerly BMBF) and the Ministerium für Kultur und Wissenschaft des Landes Nordrhein-Westfalen (MKW NRW) via the Gauss Centre for Supercomputing (GCS).
