Can you be more specific?
- snovv_crash 7y agoI've used it for bitwise hamming distance - xor+popcnt - having a hardware instruction on x86 made the entire pipeline over 6x faster.
- stochastic_monk 7y agoI’ve used popcounts for full vectorization for b-bit minwise hashing, comparing bloom filters efficiently, and bitvector traversal. It’s a standard primitive in a lot of low-level code.
