You're a researcher and intern, but asking basic questions like this? Umm...
"MIC instructions" - are you referring to the AVX512 supported in KNL
or the pre-cursor to this in KNC? (Which supported a few more and a
few less instructions than what ended up being AVX512)
I've seen a bunch of work from @Intel people around here and I'll let
them comment on more of the specifics about the level of support for
Intel PHI products.
