Kim Walisch,

a software engineer from Luxembourg, and avocational expert in prime number generation [1] [2], applying the Sieve of Eratosthenes [3]. He is knowledgeable about processor architectures, software optimization and bit-twiddling.

Population Count#

Kim Walisch provides a header-only C/ C++ library for counting the number of 1 bits using specialized instructions of various processor architectures [4], performing algorithms as described by Wojciech Muła et al. [5].
