Vectorizing Random Number Generators for Greater Speed: PCG and xorshift128+ (AVX-512 edition)
Most people designing random number generators program using regular code. If they are aiming for speed, they probably write functions in C. However, our processors have fast “vectorized” (or SIMD) instructions that can allow you to go faster. These instructions do several operations at once. For example, recent Skylake-X... Read more
