Determines the maximum of float64 vectors. On Intel® MIC Architecture, compare and jump instructions emulate this instruction. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern _m512d __cdecl _mm512_max_pd(_m512d v2, _m512d v3); |
With Mask extern _m512d __cdecl _mm512_mask_max_pd(_m512d v1_old, __mmask8 k1, _m512d v2, _m512d v3); |
v2 |
float64 vector to determine the absolute maximum values (first source operand) |
v3 |
float64 vector to determine the absolute maximum values (second source operand) |
v1_old |
Source vector that retains old values of the destination vector; the resulting vector gets corresponding elements from v1_old for zero mask bits |
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; elements in the result vector corresponding to zero bit in k1 are copied from corresponding elements of vector v1_old |
Determines the maximum value of each pair of corresponding elements in float64 vector v2 and float64 vector v3.
If the values being compared are both 0.0s (of either sign), the value in the second operand (v3) is returned. If only one value is a NaN, the second operand (v3), either a NaN or a valid floating-point value, is written to the result.
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.
Returns the result of the operation.
