#127213)Available on (x86 or x86-64) and target feature
avx512fp16,avx512vl
and x86 only.Expand description
Compute the approximate reciprocal square root of packed half-precision (16-bit) floating-point
elements in a, and store the results in dst using zeromask k (elements are zeroed out when the
corresponding mask bit is not set).
The maximum relative error for this approximation is less than 1.5*2^-12
