We have not reverse engineered any compiled code in the process of developing SCALE.

It was clean-room implemented purely from the API surface and by trial-and-error with open CUDA code.

Isn't that exactly what a "clean room" approach avoids?

oh definitely. But if I was NVIDIA I'd want to verify that in court after discovery rather than relying on their claim on a website.

good point

FWIW, I think this is really great work and I wish only the best for scale. Super impressed.
