pub unsafe fn _mm256_stream_si256(mem_addr: *mut __m256i, a: __m256i)

Available on x86-64 only.

Moves integer data from a 256-bit integer vector to a 32-byte aligned memory location. To minimize caching, the data is flagged as non-temporal (unlikely to be used again soon)

Intel’s documentation

Safety of non-temporal stores

After using this intrinsic, but before any other access to the memory that this intrinsic mutates, a call to _mm_sfence must be performed by the thread that used the intrinsic. In particular, functions that call this intrinsic should generally call _mm_sfence before they return.

See _mm_sfence for details.
