Jupiter, Europe’s most powerful super, takes maiden flight - but misses exascale orbit

Germany's long-awaited Jupiter supercomputer launched into the number four spot on the Top500 list of publicly ranked systems, dethroning Italy's HPC6 as Europe's biggest, baddest iron. Developed as part of the EuroHPC Joint Undertaking and built-in collaboration with Nvidia and French supercomputer builder Eviden (formerly …

Nice list

It's good to see the JUPITER Booster module strutting its stuff at #4 with 793 PF/s Rmax, and also Isambard-AI phase 2 at #11 with 216 PF/s. Plus it's fun to see that 1/3 (minus one) of the Top21 machines are now running ARM CPUs (plus, in non-x86, Sierra's POWER9 and TaihuLight's Sunway SW26010, are still hangin' in there at #20 and #21, since 2018 and 2016).

Also, if we count the CEA-HE upgrade (64 to 91 PF/s Rmax -- +42%) then 1/3 (minus one) of entries in the Top 1/3 of the first page of Top500 are **NeW** this June (10 new or upgraded machines in the Top33)! And that last position (#33) went up from 44 PF/s last November to 54 PF/s of Rmax now (+23%).

So, a nice incremental list, with no huge upheaval, except maybe the 50% of Top10 machines that are now in Europe (from TFA). As for China, they had started their own Top100 list at "http://www.hpc100.cn/top100/23/" a few years back, but that server is now either AWOL or MIA ... (the mystery sauce thickens!). Openness is the best policy for international competition (as well as cooperation) imho.
