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.

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.

wut

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.

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

Not enough parallelism to saturate either.

For some reason, my three day weekends don't produce things like this...
