#3I wonder if we (United States ) could get a risc v in a supercomputer .

#4> The Jupiter supercomputer, which will cost €273 million to build, will pair SiPearl’s Rhea processor, which is based on ARM architecture, with accelerator technology from Nvidia.
An ARM and a leg, for sure.

#5This is really cool, and as it uses an established architecture, can benefit from the software ecosystem that exists around it.
The article focuses basically on the x86 vs. arm competition.
Any idea where to read more about the application this machine is expected to run? I guess the usual like weather forecast and such?

#6Can report Jülich is not near Munich.... Anyway will be fascinating to see how the SiPearl chip works out.

They mixed up Garching with Jülich.

#8It seems odd to focus on the CPU here, when presumably the vast majority of those flops re coming from the NVIDIA parts?
Are the CPUs expected to contribute significant compute, as opposed to marshaling data in/out of the real compute units?

#9Isn't it mostly GPUs/accelerators based rather than CPUs?
Does NVIDIA even sell those anymore without the whole package deal since they came up with Grace?
The last supercomputer with NVIDIA GPUs and third party CPUs I remember reading about was with Zen 2 cores, multiple years ago.

Perlmutter (#8) was just commissioned into full service earlier this year and uses Zen 3 cores with A100s. Leonardo (#4) is also current year and uses Xeon CPUs with A100s. Google's H3 also seems to pair H100s with Xeon CPUs.
But yes, the CPU is mostly just a footnote, most of the FLOPs come from the GPUs. Although of course the CPUs still need to be sufficiently fast enough that the GPUs can be kept fed.
