[Beowulf] avx-512

this just came out on hpcwire

quote from the article; GPUs aren’t designed to operate on non-FP data.

the merit of the statement is probably up for debate, but that's a
pretty bold statement to make in an article in my opinion.

the article almost seemed machine-generated to me; did it actually
say anything that we didn't already know (basically, that avx-512
in skylake/purley can perform double the vector rate of avx(-256)?

yes, strange indeed. in fact, if the article is about vectorization,
one could easily argue that the GPU model for vectorization (since surely
a SM has to be considered a vector core) is in some ways working out
better than the accretion of SIMD hacks in x86_64...
