Frankly, I don't believe you. I'm half decent at writing CUDA directly (a holdover from a project a few years ago and it is a nice skill to have), the degree to which these are optimized is unlike 99.9% of all other code out there and even a tiny slip-up is either going to kill your results, your performance or both and if you're lucky only in some edge case. Understanding this code is hard work. I made a couple of minor edits to some .cu files in llama.cpp yesterday because I have a pretty weird setup which they obviously did not anticipate and it took a couple of hours to get it 'just so'.
