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.)
Part of me is glad to see AES-NI put to good use, but the other part wishes it would just die. Leveraging existing generic SIMD instructions makes much more sense than requiring algorithm-specific instruction sets.

If “rotate” can be considered a legitimate cpu primitive operation then surely there is room for something optimal for hashing?
