It also seems to suggest that it could accelerate hyperscan, but considering the hardware and software are both from Intel and they don't integrate them, maybe it doesn't work or is theoretical.
Interesting that Intel's code for this includes numerous references to LZ4, as if that's the actual algorithm the hardware originally aimed to accelerate.. So seems like LZ4 and ZSTD are quite similar?

For using accelerators (QAT, I assume, because the article is about this) from the CLI, then QATzip[3] comes with a command line tool qatzip which can be used as described in the project ReadMe. I didn't test it, though, as I have no QAT-enabled device.

It's obsolete. It's limited to 32KB LZ window with huffman coding. Zstd can use a much larger window (8MB recommended) and a much better entropy coder: https://github.com/Cyan4973/FiniteStateEntropy
