Integer division is an arithmetic operation that is not provided natively by SIMD instruction set extensions. In this article we provide a vectorized solution to successfully divide signed 64-bit integers by taking advantage of AVX-512
This article explores the possibility of branchlessly converting multiple signed 64-bit integers to strings by taking advantage of AVX-512 extensions. Most research and implementations focus on improving the performance of converting a single value instead of performing multiple conversions at once. At Sneller, we use AVX-512 to process 16 values in parallel, and thus we would like to describe how we have done it in our query engine.
