_mm256_max_pd

Determines the maximum of float64 vectors. The corresponding Intel® AVX instruction is
VMAXPD
.

Syntax

extern __m256d _mm256_max_pd(__m256d m1, __m256d m2);
Arguments
m1
float64 vector used for the operation
m2
float64 vector also used for the operation
Description
Performs a SIMD compare of the packed double-precision floating-point (float64) elements in the first source vector
m1
and the second source vector
m2
, and returns the maximum value for each pair.
Returns
Maximum value of the compare operation.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
