"SC25 Europe has officially entered exascale orbit. On Monday, EuroHPC's Jupiter supercomputer became the fourth such machine on the Top500 list of publicly known systems to exceed a million-trillion floating point operations a second in the time-honored High-Performance Linpack (HPL) benchmark. Built by Eviden and powered by Nvidia's Grace-Hopper GH200 superchips, the Jupiter Booster made its maiden flight at the International Supercomputing Conference in June where it managed 793 petaFLOPS of HPL performance in a partial run that established it as Europe's most powerful super."
"So far we've only seen benchmark runs from the Booster section of the system, which comprises roughly 6,000 of Eviden's BullSequana XH3000 nodes, each of which is equipped with four GH200 superchips. In total, the Booster section is equipped with roughly 24,000 superchips which are theoretically capable of churning out somewhere between 872 petaFLOPS (vector) and 1.6 exaFLOPS (matrix) performance."
EuroHPC's Jupiter supercomputer surpassed one exaFLOPS on the High-Performance Linpack (HPL) benchmark, marking a public European double-precision exascale achievement. Eviden built Jupiter and the system's Booster is powered by Nvidia Grace-Hopper GH200 superchips. The Booster achieved 793 petaFLOPS in a June partial run and delivered over one exaFLOPS in a recent HPL measurement. The Booster comprises about 6,000 BullSequana XH3000 nodes with four GH200 chips each, totaling around 24,000 superchips and theoretical performance from 872 petaFLOPS (vector) to 1.6 exaFLOPS (matrix). A Universal Cluster CPU partition based on SiPearl Rhea1 processors with 80 Neoverse V1 cores and 64 GB high-bandwidth memory will come online later, adding additional CPU performance.
