# _mm256_stream_pd

Moves packed double-precision floating-point values using non-temporal hint. The corresponding Intel® AVX instruction is VMOVNTPD.

## Syntax

extern void _mm256_stream_pd(double *p, __m256d a);

## Arguments

*p | pointer to a memory location that can hold double-precision floating point (float64) values; the address must be 32-byte aligned
a | float64 vector

## Description

Performs a store operation by moving packed double-precision floating point values (float64 values) from a float64 vector, a, to a 256-bit aligned memory location, pointed to by p, using a non-temporal hint to prevent caching of the data during the write to memory.

## Returns

Result of the streaming/store operation.
