  "account": "Europe's fastest supercomputer, Jupiter, is set to incorporate domestic silicon in the form of SiPearl's Rhea1 CPUs. The delivery of these chips began on Tuesday, marking a significant milestone for digital sovereignty. Jupiter, which entered service last year, was initially powered by 24,000 American-made Nvidia GH200 superchips, making it the fifth most powerful system on the Top500 ranking. However, the CPU-only partition will now be powered by Rhea1 chips, developed over several years by SiPearl. This chip, based on Arm's Neoverse V1 core designs, boasts 61 billion transistors and is designed specifically for high-performance computing and scientific workloads. The Rhea1's high memory bandwidth makes it well-suited to applications that require efficient access to large amounts of data. With 80 cores per chip, each equipped with four stacks of 64 GB HBM2e memory and four DDR5 memory channels, the Rhea1 is expected to bring substantial computational capabilities to the European supercomputing landscape. Thomas Lippert, director of the Jülich Supercomputing Centre, emphasized the importance of this development for the scientific community. Anders Dam Jensen, executive director of EuroHPC JU, hailed the delivery as a major turning point for the EU's HPC ecosystem.",
