Introducing the Meow hash - a non-cryptographic hash capable of 16 bytes _per cycle_ throughput on modern CPUs while still cleanly passing all of smhasher: https://mollyrocket.com/meowhash (This is an alpha version. Comments welcome on the GitHub.)

I will be posting a blog update explaining things, but the TL;DR is that you can do a hash-of-hashes construction to break the serial dependency of AESENC/DEC-based hashing and get it down to 1 cycle per SIMD-block processed, and it scales with the SIMD size.

So today it's 128 bits per cycle, tomorrow it will be 512 if the VAES instruction set delivers similar timings (which it might not, but the design is future-proofed for it, so the hash values won't change when it widens).
