FYI: the follow-up to the current Xeon Phi "KNL" has been canceled and
it's possible that the entire product line has been discontinued.
Also, most codes run faster these days on 2S SKL systems than on KNL

I don't fully understand the question, are you asking about multicore scaling?

Not sure what you mean, Xeon Phi (KNL) is not used in offload more.
