Sorry, I got distracted. If it were up to me, I'd prefer tuning numbers that are, without checking, unambiguously better than the current code gen. In particular the code gen for KNL is awful. Furthermore, I think that fine tuning this further has diminishing returns for various reasons. Are people okay with that?
