Chapter 10
Vectorization advisor
Abstract
Introduces the Intel Vectorization Advisor, which provides AVX-512 analysis capabilities to help reach the vectorization potential of Knights Landing. For scalar loops, it helps to discover what prevents code from being vectorized. For vectorized loops, it provides detailed AVX-512 performance characterization. Recommendations are additionally supplemented with the AVX-512 Traits and FLOPs, masks, Roofline, and Gather/Scatter reports.
