Bull has begun integration of Rhea1 onto its BullSequana XH3000 platform for JUPITER, Europe’s first exascale supercomputer. Procured by the EuroHPC Joint Undertaking, JUPITER is hosted at Jülich Supercomputing Centre (JSC). According to SiPearl’s announcement, this milestone will contribute to the development of JUPITER’s CPU blade, which complements the GPU partition, paving the way for full modular integration of the machine.
The most complex server CPU ever designed in Europe, Rhea1 includes 80 Arm® Neoverse V1 cores - each with 2 x 256-bit Scalable Vector Extension -, four stacks of high-bandwith memory (HBM), and four DDR5 memory interfaces.
‘The delivery of the first Rhea1 CPUs marks an important milestone for Europe’s supercomputing sovereignty. Through the European Processor Initiative, EuroHPC JU has supported the development of a European processor that is now moving from innovation to deployment in JUPITER, Europe’s first exascale supercomputer. This achievement demonstrates what Europe can accomplish by bringing together research, industry and world-class infrastructure to build a stronger European HPC ecosystem,’ said Anders Dam Jensen, executive director of EuroHPC JU.
SiPearl was founded as part of the European Processor Initiative, an EU-funded project to develop designed-in-Europe chips for HPC.
