Jupiter will be Europe's first exascale supercomputer, and located in Forschungszentrum Jülich facilities in Germany.

A project under the European High Performance Computing Joint Undertaking (EuroHPC JU), Eviden has been selected alongside German modular supercomputing company ParTec to provide the supercomputer.

The project is expected to cost around €500 million ($525.4m) of which half will be provided by EuroHPC JU and the other half by the German Federal Ministry of Education, and the high-performance computing (HPC) cluster will ultimately be operated by the Jülich Supercomputing Centre. The computer will cover the space of around four tennis courts and will need over 260km of cabling.

Jupiter is to be comprised of GPUs and CPUs from Nvidia and SiPearl split between a "Booster Module" and a general purpose "Cluster Module" and will be capable of one trillion calculations per second. The Cluster Module will use the SiPearl Rhea processor which is based on Arm's Neoverse V1 CPU design.

It will be based on Eviden's BullSequana XH3000 direct liquid-cooled architecture.

Emmanuel Le Roux, group SVP and global head of HPC, AI & Quantum at Eviden, Atos Group said: “Providing the first Exascale supercomputer in Europe, based on our BullSequana XH3000, is a moment of true pride for our teams.

"For as long as we have been providing computing technologies, we have been supporting European countries in their journey to economic and industrial sovereignty. The European scientific community will now benefit from a remarkable ‘made in Europe’ machine to tackle scientific challenges and stimulate innovation.”

Installation is planned to begin in early 2024.

SiPearl is based in France and began developing the Rhea processor with seed funding from the European Processor Initiative which aims to develop chip designs that remove current reliance on foreign chip technologies.

“We are thrilled that Rhea1, our energy-efficient HPC-dedicated microprocessor, will fuel part of Europe’s first Exascale supercomputer," said Philippe Notton, CEO and founder of SiPearl.

"This validates EuroHPC’s vision in creating the European Processor Initiative consortium, which incubated SiPearl. We look forward to working with Jülich, Eviden, and ParTec in bringing the groundbreaking Jupiter system to life. Together, we will contribute to European technological sovereignty while dramatically reducing the carbon footprint of supercomputing and artificial intelligence.”

The EuroHPC JU is planning a second exascale supercomputer that will be hosted in France by the end of 2025. Announced in June, the HPC will be hosted and operated by the Jules Verne Consortium.
