Expand description

Compute dot-product of BF16 (16-bit) floating-point pairs in a and b, accumulating the intermediate single-precision (32-bit) floating-point elements with elements in src, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
