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

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

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.

I, too, was once highlighted by DCD once on a move (to Azure).
Enjoy the ego stroke 😁

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.

Having watched engineers do the hybrid HPL run on Trinity, you should be sure to give anyone who attempts it lots of love (and a raise 😄)

There are none installed so the numbers would be the same. 😋 Once they come, they could try to do a hybrid run, but it would be an enormous pain to do and not much upside.
