AVX/SSE scalar and packed double precision FLOP rates. The Xeon Phi (Knights Landing) provides
|
|
no possibility to differentiate between double and single precision FLOP/s. Therefore, we only
|
|
assume that the printed [MFLOP/s] value is for double-precision code. Moreover, there is no way
|
|
to distinguish between SSE, AVX or AVX512 packed SIMD operations. Therefore, this group prints
|
|
out the [MFLOP/s] for different SIMD techniques.
