libmorton VS AMVtool

I used it to accelerate nearest neighbor detection for collision processing in particle-laden flow for modeling complicated domains in 3d (for biological fluids simulation). I was using it a locality sensitive hashing to put particles near each other in the same bucket in an hash map. I came across the ideas of BIGMIN (big minimum) and LITMAX (little maximum) for range search in a morton encoded data that I found to be cool.

For example, I was able to accelerate ARM's vector-based arithmetic/logical bit-shifts into a single instruction compared to the 5 instructions it needed before thanks to AVX-512(also here's a little writeup I made on that). Or how I was able to accelerate ARM's vector bit-reversal into a just 2 fast instructions rather than the dozen that it needed before(another write-up I made on that). Or how using AVX512-BITALG can help accelerate interfacing with Morton Codes(common with encoding and decoding GPU texture formats).

What I can suggest: Get some nice Blu Ray remuxesor Web rips in h.264 from nyaa.si They probably come in .mkv. However you can remux (copy videostreams to mp4 files) fast and easy with this: https://github.com/l33tmeatwad/AMVtool
