something with a little more technical detail: https://www.fz-juelich.de/en/ias/jsc/jupiter/tech looks like its just a big Nvidia installation. IB, Ceph, K8s, H100s

Don't know why your're downvoted, this is valid criticism. EU just bought 500 mil worth of hardware from the US, no specific European innovation, apart from system management (ParTec Italy). But would be happy to be proven otherwise.

Germany got European taxpayers to buy them US hardware. That's a fairly normal day in the EU.

"With JUPITER, Europe becomes the home of the most powerful computer in Europe" -- Henna Virkkunen What does that mean?

Confusing grammar aside, the most powerful computer before this was HPC6 in Italy which is definitely in Europe.

Who exactly were you going to buy equipment from? AMD/Nvidia/Intel are the only players in town.

China with SMIC and Huawei's Ascend 910C would be an example of what you do if you want to pursue strategic autonomy. It's like asking "who exactly were you going to buy a 6th generation fighter from?"

From the add I did over on WP Current Events, based on the June preliminary system test (data from Top 500 https://top500.org/lists/top500/2025/06/):

"It is currently being commissioned and has achieved a preliminary HPL value of 793.4 Petaflop/s on a partial system."

Top 500 Rank: 4 (behind El Capitan, Frontier, and Aurora at the DOE)

System Config: JUPITER Booster - BullSequana XH3000, GH Superchip 72C 3GHz, NVIDIA GH200 Superchip, Quad-Rail NVIDIA InfiniBand NDR200, RedHat Enterprise Linux

Manufacturer: EVIDEN https://eviden.com/solutions/high-performance-computing/hpc-...

Location: EuroHPC/FZJ, Germany https://www.fz-juelich.de/en/ias/jsc/jupiter

Cores: 4,801,344

Rmax (PFlop/s) / Rpeak (PFlop/s): 793.40 / 930.00

Power (kW): 13,088

US Hardware, with essential components manufactured in Taiwan with European technology.

Seems like it has 5 petaflops of compute from a SiPearl (French) designed Rhea-1

Edit: that might be speculative or a future addition cause they taped out less than 2 months ago https://www.eetimes.eu/sipearl-tapes-out-rhea1-processor-clo...

Which was delayed 2 years. I’m speculating this was supposed to be mostly or exclusively this but they needed a computer now. Or needed to spend the budget now.
