Europe to launch first ARM-powered exascale supercomputer

Share post:

Europe is poised to launch the world’s first ARM-powered exascale supercomputer, Jupiter. The project is a collaboration between the European High-Performance Computing Joint Undertaking (EuroHPC JU), computing firms Eviden and ParTec, and chipmakers SiPearl and Nvidia.

Jupiter will be installed at the Jülich Supercomputing Centre in Munich, Germany, and is scheduled to begin assembly in early 2024. The system will be powered by SiPearl’s Rhea processor, which is based on ARM’s Neoverse V1 CPU design. Rhea is a 72-core chip that supports HBM2e high-bandwidth memory and DDR5.

Jupiter will also feature Nvidia’s Booster Module, which includes GPUs and Mellanox ultra-high bandwidth interconnects. The specific Nvidia chips that will be used in Jupiter have not yet been announced, but the current-gen H100 GPU is a likely candidate.

Once completed, Jupiter is expected to be one of the most powerful supercomputers in the world. The system is expected to deliver performance of over 1 exaflop, which is equal to 1 quintillion (10^18) floating point operations per second.

Jupiter will be used by a wide range of scientists and researchers to tackle some of the world’s most challenging problems, such as climate change, drug discovery, and materials science. It is also expected to create hundreds of jobs in Europe.
