sipearl

SiPearl is the French chip designer behind the Rhea1 processor, and this tag follows its progress from lab validation into real customer systems. The most recent coverage tracks SiPearl delivering its first Rhea1 samples to Bull, which has begun integrating them into the BullSequana XH3000 platform for JUPITER, Europe's first exascale supercomputer at Germany's Jülich Supercomputing Centre. The chips are destined for a CPU-only partition alongside the machine's existing Nvidia-powered Booster, which is not being replaced. Performance figures are still being finalised, so the story remains one of early integration rather than confirmed benchmarks, with a broader thread of European processor independence.
