Europe gets ARM-based supercomputer

Jupiter of the world's most powerful

One of the world's most powerful supercomputers will soon be online in Europe, using ARM-based chips instead of x86 parts.

Jupiter is a project of the European High-Performance Computing Joint Undertaking (EuroHPC JU), which is working with computing firms Eviden and ParTec to assemble the machine.

Europe's first exascale computer will be installed at the Julich Supercomputing Centre in Munich, and assembly could start as soon as early 2024.

EuroHPC has opted to go with SiPearl's Rhea processor based on ARM architecture. Most of the top 10 supercomputers in the world are running x86 chips, and only one is running on ARM.

Rhea is based on ARM's Neoverse V1 CPU design, developed specifically for high-performance computing (HPC) applications with 72 cores. It supports HBM2e high-bandwidth memory and DDR5, and the cache tops out at an impressive 160MB.

Nvidia also gets a slice of the action. According to the press release the Jupiter system "will have Nvidia's Booster Module, which includes GPUs and Mellanox ultra-high bandwidth interconnects, "and will likely include the current-gen H100 chips. "When complete, Jupiter will be near the top of the supercomputer list."
