There is a good chance we can arrange remote access to hardware within Intel. Otherwise I can ask one of the DOE labs that has test hardware if they can help. (A lab that doesn't have onerous remote access limitations...). If all else fails, we loan out development boxes for certain purposes. > > But > wikipedia claims there is not much hardware out there (yet?) that has > support for it: https://en.wikipedia.org/wiki/AVX-512#CPUs_with_AVX-512 > > Intel Xeon Phi 72xx aka Knights Landing is the only generally available product that supports it.

Many DOE labs use it heavily. I wish I could help implement but I don't have the relevant skills.
