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

bayindirh•5mo ago

If that’s “so simple”, why we don’t see everyone “just” doing the same?

BrouteMinou•5mo ago

It might just be expensive... Some other countries might just not need those when they are struggling to get fresh water...

And so on, but that's just my 2 cents.

wqweto•5mo ago

Europe is not a country.

liotier•5mo ago

Federal Europe is a proto-country - and we are already citizens of the European Union. In short: Europe is my country !

BrouteMinou•5mo ago

"Everyone" doesn't apply just to continents, isn't it?

dotnet00•5mo ago

To be fair, being "just" a big Nvidia installation doesn't really mean that it's "so simple" (person you're replying to didn't claim it was simple), considering that every "Nvidia installation" has a slightly different set of factors like node count, per node memory, CPU choice, and networking configuration. All it says is, like many (most?) other modern supercomputers, it's a giant NVIDIA GPU cluster.

> a 21 Petabyte Flash Module (ExaFLASH) is provided based on the IBM Storage Scale

Nice. How much does this cost?

> The scratch storage is based on 20 IBM Storage Scale 6000 systems utilizing NVMe disk technology, based on the IBM Storage Scale solution. With 29 PB of raw and 21 PB of useable capacity

That's also a lot of waste, isn't it?

conception•5mo ago

With 29 PB of raw and 21 PB of useable capacity.

RAID gonna RAID.

poisonborz•5mo ago

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.

frodo8sam•5mo ago

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

themgt•5mo ago

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?"

timlatim•5mo ago

Without questioning this idea on political grounds, I am not sure if it would be at all possible for an Ascend 910C cluster to enter the supercomputer rankings. I could not find a public datasheet on this chip (would appreciate a link), but my impression is that it is an AI accelerator that does not target FP64, whereas TOP500 is looking at HPC (FP64) performance [1].

standardUser•5mo ago

Until a year ago, few thought there would ever be a need for Europe to have strategic autonomy from the US in an area that was already solved by trade agreements. Presumably this project was conceived long before that.

mrtksn•5mo ago

It was probably more like system designed in Europe, made in China, assembled in Europe thing.

Sure, the HQ of the core component(Nvidia) is incorporated in US but that too is a multinational effort.

mytailorisrich•5mo ago

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

OKRainbowKid•5mo ago

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

notrealyme123•5mo ago

Don't forget it's made in china.

StrangeDoctor•5mo ago

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.

croes•5mo ago

So US supercomputers aren’t an achievement because they just bought chips from Taiwan and those aren’t also an achievement because they bought photolithography machines from ASML in Europe?

Since when are supercomputers anything other than just the ability to afford a lot of hardware?

"With JUPITER, Europe becomes the home of the most powerful computer in Europe" -- Henna Virkkunen

What does that mean?

jerf•5mo ago

My guess is that it means that not only does "Henna Virkkunen, Executive Vice-President for Tech Sovereignty, Security and Democracy" write her quotes with AI without reading them carefully, but that she's also doing it with an older model.

pona-a•5mo ago

Maybe they wanted to say “with [JUPITER, Europe],” as in “CERN, Switzerland.” This would still be unnecessary and confusing, but that’s the most sense I can make of it.

vjvjvjvjghv•5mo ago

I am assuming before JUPITER the most powerful computer in Europe was not at home in Europe?

shreddit•5mo ago

To quote zefrank: The tallest giraffe is taller than all other giraffes

bprew•5mo ago

I took it to mean that the controller of the most powerful computer in Europe is Europe, as opposed to Apple or Google or another private entity.

wvbdmp•5mo ago

I think it’s pretty clear if you read the rest of the sentence, which you’ve omitted: “and the fourth most powerful in the world”. If she hadn’t said “in Europe”, the whole top 3 might be in Europe as well.

johnfn•5mo ago

I mean, it's a straightforward enough statement. But what was happening in Europe before..?

npalli•5mo ago

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

https://www.top500.org/lists/top500/2025/06/

https://en.wikipedia.org/wiki/Supercomputing_in_Europe

WaltPurvis•5mo ago

Your Top 500 link says something completely different:

"The 65th edition of the TOP500 showed that the El Capitan system retains the No. 1 position. With El Capitan, Frontier, and Aurora, there are now 3 Exascale systems leading the TOP500. All three are installed at Department of Energy (DOE) laboratories in the United States."

HPC6 is listed below those, and far less powerful.

npalli•5mo ago

In Europe, HPC6 was the fastest before Jupiter. It was No.4 last year and 6th now that JUPITER is taken 4th place.

WaltPurvis•5mo ago

Yes, but that fact does nothing to make the statement in question more sensible, so I don't know why you bothered to point it out, or to emphasize the "HPC6 [is] in Italy which is definitely in Europe" aspect. (Although I don't think the statement in question was all that nonsensical to begin with — IMO, it was just inartfully phrased.)

jujube3•5mo ago

Sounds like a dril quote.

pchangr•5mo ago

I believe this refers to the fact that, before Jupiter, the most powerful computer in Europe was HPC6, which is owned by Eni S.p.A, a private company, and the following most powerful computer was the Alps system, located in Switzerland. So, in this context, this new supercomputer is owned by Europe, “the public” and it’s located in the European Union sovereignty within Europe, the continent.

Edit: I found the full quote in the website of the Jülich Development Center and I guess it makes sense why it was editorialized for the eu-wide website.

“This is a historic milestone. With JUPITER, Europe is reaching the highest level of high-performance computing. JUPITER is also a testimony for Germany's long leadership in HPC. Today, it became the home of the most powerful computer in Europe and the fourth most powerful in the world. From European perspective, JUPITER is a pioneer. It shows that when we combine national vision with European cooperation, we can achieve global excellence.”

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."

Looks like a research cluster. Universities / their Researcher can apply for reasources instead of setting up own hardware.

Zyten•5mo ago

Quite a varied field of research. From Computer Science and Neuroscience to Climate Research and more. You can find an overview for some of the HPC systems here: https://www.fz-juelich.de/en/ias/jsc/systems/supercomputers/...

Rover222•5mo ago

How do the gpu training clusters rank against the traditional “largest supercomputer” metric? Or is that comparing apples to oranges?

I think by some measures XAi already has the largest (200k H100 equivalent) and already constructing the 1 million gpu cluster.
