JUPITER is Europe's fastest supercomputer

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 sustainable energy system.

The JUPITER booster, supplied by Eviden, is ultimately equipped with around 24,000 GH200 Grace Hopper superchips from NVIDIA, which are optimized for highly parallel applications such as AI training and numerically demanding simulations. This enables, for instance, the training of the largest AI models, known as large language models (LLMs). At full capacity, JUPITER needs less than one week to complete the task.

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, 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 Federal Ministry of Research, Technology and Space (BMFTR, formerly BMBF) and the Ministry of Culture and Science of the State of North Rhine-Westphalia (MKW NRW) via the Gauss Centre for Supercomputing (GCS).
