Synopsis
_mm512_mask_mul_round_ph(__m512h src, __mmask32 k, __m512h a, __m512h b, int rounding);
Description
Multiply packed half-precision (16-bit) floating-point elements in "a" and "b", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
