VPU intensity offers a rule of thumb on how well a loop is vectorized, calculating the proportion of vectorized operations on total arithmetic operations. This metric should be applied only to small pieces of code and certain non-arithmetic operations, such as mask manipulation instructions, are counted as vector operations, which can skew this ratio.
UOPS RETIRED.PACKED SIMD/ (UOPS RETIRED.PACKED SIMD + UOPS RETIRED.SCALAR SIMD)
For more details, see KNL Vectorization metrics.
