I'm an amateur, but I have code that I think could probably dispatch threads pretty efficiently on the Cheyenne thru it's management system simply because it's all xeons distributed. If I can run it on my personal 80-core cluster, I could get it to run on Cheyenne back then.

But hitting the roofline on those AMD GPGPU's? I'd probably get nowhere fucking close.

That is the thing that Cheyenne was built for. People doing CFD research with x86 code that was already nicely parallelized via OpenMPI or whathaveyou.

It is wild how much compute has grown.

I put dual Epyc 9754 into my first box of MI300x.

That's 256 cores + 8x MI300x, in a single box.

Agreed, it is a great solution for CFD, which is definitely one workload I'd love to host.
