WebWe had to create AVX versions of a, b and c, which we called avx_a, avx_b and avx_c. These were declared as aligned arrays of __m256 vectors, with the array containing size/8 elements (as each vector holds eight floats). We had to populate avx_a and avx_b using the _mm256_set_ps function. We had to initialise avx_c to zero using the _mm256_set1 ... WebThis code snippet emits the correct intrinsic depending on if streaming stores are enabled and the preprocessor flag definitions. Depending on the value of streaming and the AVX-512 macro, the intrinsic emitted will be: _mm512_stream_ps: Knights Landing-specific streaming store. _mm512_storenrngo_ps: Knights Corner-specific streaming store.
