From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
Crazy to not see a word about benchmarking/evaluation of the kernels. IMO at this time when all performant GPU kernels are generated/hill-climbed, its the largest source of error we see. Should be kernel run with a hot or cold cache in practice? Should your kernel be bitwise equivalent to a ref? What error margins…
> On the H200s used for most of this work, the GPU's main memory is HBM, or high-bandwidth memory. Ironically, this is the slowest memory on the chip. Nit: HBM is off chip, unlike shared memory and registers
