Intel® C++ Compiler 16.0 User and Reference Guide
Scatter int32 vector with int32 indices. Corresponding instruction is VSCATTERDD. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
Without Mask extern void __cdecl _mm512_i32extscatter_epi32(void* mv, __m512i index, __m512i v1, _MM_DOWNCONV_EPI32_ENUM conv, int scale, int hint); extern void __cdecl _mm512_i32scatter_epi32(void* mv, __m512i index, __m512i v1, int scale); |
With Mask extern void __cdecl _mm512_mask_i32extscatter_epi32(void* mv, __mmask16 k1, __m512i index, __m512i v1, _MM_DOWNCONV_EPI32_ENUM conv, int scale, int hint); extern void __cdecl _mm512_mask_i32scatter_epi32(void* mv, __mmask16 k1, __m512i index, __m512i v1, int scale); |
Down-converts and stores all 16 elements in int32 vector v1 to the memory locations to which the base address(es) mv and vector index index, with scale scale point.
The non-masked variant of the intrinsic is equivalent to the masked variant with full mask (k1=0xffff).
You can use the simplified version of this intrinsic, without ext in the name, if no conversion and no temporal hint are required.
None.
