Faster bitset decoding using Intel AVX-512

Faster bitset decoding using Intel AVX-512

I refer to “bitset decoding” as the action of finding the positions of the 1s in a stream of bits. For example, given the integer value 0b11011 (or 27 in decimal),  I want to find 0,1,3,4. In my previous post, Fast bitset decoding…
