HPC Architecture Ronin, currently at Nvidia. ex-MSFT, but forever a Crayon. I am proud of my home state (MN) and you will hear about it. All posts (especially the dumb ones) reflect my own positions and not that of my employer.

NVIDIA Acquires Open-Source Workload Management Provider SchedMD NVIDIA will continue to distribute SchedMD’s open-source, vendor-neutral Slurm software, ensuring wide availability for high-performance computing and AI.

As hybrid #HPC + #AI + #Quantum workflows become more prevalent, orchestration of complex systems is becoming a key component of successful deployment. Looking forward to accelerating these capabilities for the open-source community.

I wrote up my notes from #SC25. Have a look: blog.glennklockwood.com/2025/12/sc25...

I’ll keep picking away at the editing, but would love to hear more from others about what stood out to them. I wasn’t at the conference itself as much this years as in the past, so I know I missed a lot.

The future of supercomputing will be AI accelerated Interview: Nvidia's Ian Buck on the importance of FP64 to power research, in a world that's hot for inferencing

You're right, it's not dead! 😁

Ozaki does not replace FP64. It just makes DGEMM faster. Why is that bad?

That was the best analogy, though!

Reminds me of Seattle in 2011. Didn't want to be a vendor in the "kid's table" hall.

My 13yo showed me this passage in a book he was reading the other day. My response: "yeah, I've got one of those (blades) in my office". 😄

Yeah, this has been a go-to for years. Becoming especially important lately trying to find facts in the AI hype cycles.

The only office in the Twin Cities was for educational software and Office trainings, last I looked.

That would have been super valuable

The extra fun trivia is that I posted that message while sitting at the project kick-off meeting in Tokyo. :-)

That's a DFMA target number. Not GEMM.

To be chosen to participate in the design of the next iteration is a massive honor for us.

Through this partnership, we aim to develop a scientific discovery ecosystem based on the full integration of simulation and AI. We hope this work will benefit not only Japan, but also researchers worldwide.

RIKEN, Japan’s Leading Science Institute, Taps Fujitsu and NVIDIA for Next Flagship Supercomputer Japan is once again building a landmark high-performance computing system — not simply by chasing speed, but by rethinking how technology can best serve the nation’s most urgent scientific needs. At t...

Those who have been around #HPC a while know the historical significance (and probably the names) of Japan's flagship supercomputers. They always push the boundaries of technology, but in ways that are driven uniquely by the needs of Japan.

Those numbers were from their feasibility study and not necessarily where the design will land.

I, too, was once highlighted by DCD once on a move (to Azure).

This is a well-known Minnesota-ism, so I've been polluted from birth.

If it makes you feel better, it bugs the heck out of my wife.
