I'm learning a lot. Thanks for sharing.

Are there libraries that make use of this instruction set to handle arbitrary length vectors?

Thanks for taking the time to have a look at my article! The conclusion of this article is in the pipeline, and should be published in a few days.

Regarding your question, not that I know of, but then I don't really know what products are using this technology. Most of my efforts have been spent in just figuring out how to use this stuff. The AVX-512 instruction set has about a dozen subsets, some of which are yet to be released. One of the yet-to-be-released subsets is AVX-512VNNI (vector neural network instructions), and is designed to accelerate convolutional neural network algorithms (https://en.wikichip.org/wiki/x86/avx512vnni).

As far as who else is using this technology, the AVX-512 stuff is pretty new, so, and makes some heavy hardware demands. I think the situation is a bit like when Intel and AMD came out with 32-bit processors in the mid-80s, but it took about 10 years for OSes to catch up.
