Permutation in Intel Xeon Phi

I hope this helps you . Suppose I have the following 4 vectors of doubles in Xeon Phi registers: , Answered by Evgueni Petrov in the Intel forums:
__m512i a1 = (__m512i)_mm512_mask_blend_pd(0x33, B, _mm512_swizzle_pd(A, _MM_SWIZ_REG_BADC));
__m512i a0 = (__m512i)_mm512_mask_blend_pd(0xcc, A, _mm512_swizzle_pd(B, _MM_SWIZ_REG_BADC));
__m512i a3 = (__m512i)_mm512_mask_blend_pd(0x33, D, _mm512_swizzle_pd(C, _MM_SWIZ_REG_BADC));
__m512i a2 = (__m512i)_mm512_mask_blend_pd(0xcc, C, _mm512_swizzle_pd(D, _MM_SWIZ_REG_BADC));

__m512d C_new = (__m512d)_mm512_mask_alignr_epi32(a2, 0x00ff, a0, a0, 8);
__m512d A_new = (__m512d)_mm512_mask_alignr_epi32(a0, 0xff00, a2, a2, 8);
__m512d D_new = (__m512d)_mm512_mask_alignr_epi32(a3, 0x00ff, a1, a1, 8);
__m512d B_new = (__m512d)_mm512_mask_alignr_epi32(a1, 0xff00, a3, a3, 8);

it fixes the issue There are a few options I can list here to use/get the Intel compiler...gcc, as you know, is not equipped to vectorize code for this platform.

wish help you to fix your issue 3100 series is a first generation of Xeon Phi (codenamed Knights Corner, abbreviated KNC).

What is lost in going from AVX512 on Intel Xeon Phi to AVX2 on Intel i5-8259U?

wish helps you TL:DR: KNL (Knight's Landing) is only good at running code specifically compiled for it, and thus gets a much bigger speedup because it stumbles badly running "generic" code.
Coffee Lake only gets a speedup of 2 from 128-bit SSE2 to 256-bit AVX, running both "generic" and targeted code optimally.
