Hi all, I performed a quick test to understand the behaviors of _mm256_load_ps and _mm256_loadu_ps SIMD intrinsic respectively, and the behavior is
ssereg1 = _mm512_loadu_ps(&Hy[k-1]);// Exssereg4 = _mm512_sub_ps(vHz[vk], vHz01[vk]);ssereg4 = _mm512_mul_ps(ssereg4, vrHdy);ssereg3 = _mm512_sub_ps(vHy[vk], ssereg1);//ssereg3 = _mm512_mul_ps(ssereg3, vrHdz[vk]);//ssereg3 = _mm51...
