I thought because of the branch name they used for their PR that it was going to be a joke PR, but the mathematics of it is outside of what I understand well enough to judge if it’s legit. But from the way it reads it sounds honest.
So assuming that it is legit, it sounds really intriguing especially because of the claim they make that it “breaks the loop-carried dependency for fast generators, unlocking vectorization and parallelization where it was previously impossible”.

- saagarjha 5y agoIt's legit.
- burnished 5y agoIf I understand correctly the reason for that claim is they know in advance how many bits they will need to essentially guarantee a good sample, so instead of needing to perform the operation first to find out where the next operation can start they can just chunk it out and do it in parallel.
