Whether it be the digital transformation, climate protection, the energy transition, or the development of a sustainable circular economy, it takes a great deal of computing power to solve many of the big issues facing humanity. JUPITER will provide a huge boost for research in these areas – for the development and use of artificial intelligence, as well as for simulations and data analysis.
JUPITER, the first European exascale supercomputer, is set to be launched at Forschungszentrum Jülich. “Joint Undertaking Pioneer for Innovative and Transformative Exascale Research”, or JUPITER for short, is the first system in Europe with a computing power of more than one quintillion floating-point operations per second. JUPITER is set to achieve the performance of one exaflop/s with double the precision (64 bits) typically required for scientific simulations. For the training of AI models, JUPITER is expected to achieve over 70 exaflop/s for calculations with lower accuracy (8 bits). This would make JUPITER one of the fastest computers for AI in the world.
JUPITER is a dynamic modular supercomputer with two parts: a highly scalable booster module for particularly compute-intensive problems, which is massively supported by GPUs, and a cluster module that can be used very universally for all kinds of tasks, especially for complex, data-intensive tasks. Both modules can solve scientific problems separately or together, depending on what is required.
As with all supercomputers, researchers who want to use JUPITER must apply for the limited computing time to work on their projects. Projects from Jülich also undergo a strict selection process here. In 2024, around 100 projects, many of them involving Jülich, submitted applications as part of the JUPITER Research and Early Access Program (JUREAP). This enabled around 30 applications to be launched. Further calls for participation for computation time are pending. The Jülich Supercomputing Centre operates JUPITER as a member of the Gauss Centre for Supercomputing – an association of the three national supercomputing centres in Germany.
