Returns a float32 scalar value of an addition operation. There is no corresponding instruction. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern float __cdecl _mm512_reduce_add_ps(_m512 v2); |
With Mask extern float __cdecl _mm512_mask_reduce_add_ps(__mmask16 k1, _m512 v2); |
v2 |
float32 vector used for the addition operation |
k1 |
Writemask; only those elements of the source vectors with corresponding bit set to '1' in the k1 mask are computed and stored in the result |
Adds up all the elements of the float32 vector v2 and returns a scalar value. The addition operation is illustrated as follows:
v[0] + v[1] + v[2] + ...+ v[n] = scalar value
The masked variant has one additional argument: k1. Only those elements in the source registers with the corresponding bit set in vector mask k1 are used for computing. Elements in v2 with corresponding bit clear in k1 are copied as is to the resulting vector.
Returns the scalar value of the addition operation.
