Static analysis presumes the loop may benefit from AVX-512 Exponential and Reciprocal (AVX-512ER) instructions currently supported only on Intel® Xeon Phi™ processors, but these instructions were not used. To fix: Use one of the following compiler options:
- xMIC-AVX512 - tells the compiler which processor features to target, including instructions sets and optimizations it may generate, including AVX-512ER.
- axMIC-AVX512 - tells the compiler to generate multiple, feature-specific, auto-dispatch code for Intel processors if there is a performance benefit.
