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.

Less than six months later, Jupiter became the first public system outside the US to exceed one exaFLOPS of double precision performance. We'll note that China is believed to possess sev
