Europe joins US as exascale superpower after Jupiter clinches Top500 run

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 …

But will it run Doom?

It should be able to run Zork at least!

Nice

Good to see Jupiter hitting 1.00 EF/s in 16 MW. That makes it #14 in Green500 for power efficiency, which is the first position in Exascalers (eg. El Capitan is #23). That's the right direction to go towards.

CHIE-4 is also interesting as the highest performing Xeon+B200 system so far. Its 24x MxP speedup is remarkable and hopefully won't be revised down as Tsubame4 was -- from 25x in Nov. '24 to a still respectable 16x in June '25. It's also neat that its HPCG perf is around 3% of its oomph on HPL, which is close to the ratio on CPU-only systems (Fugaku, Crossroads), better than other CPU+GPU machines (typ. near 1%), but still below vector engines (AOBA-S, TSUBASA, near 5%). If that's due to Blackwell (GPUDirect RDMA enhancements?) then it's great design, and I can't wait to see what the MI430X riposte will do!
