Kind of, but not any particular GPU.

The machine is fake and simulated: https://github.com/anthropics/original_performance_takehome/...

But presumably similar principles apply.

It's a test of polyhedral layout algebra, what NVIDIA calls CuTe and the forthcoming C++ standard calls std::mdspan.

This is the general framework for reasoning about correct memory addressing in the presence of arbitrary constraints like those of hardware.

You can get pretty far without needing to care about this fwiw

Not far enough if you're turning cash into waste heat with GPUs :)
