It is not that they can't work with integers, but rather that they work better with floating-point values. – Scott Hunter Feb 20 '15 at 19:40 add a comment | 0 When allowing for vectorization, the double precision implementations uses fma instruction and vmulpd, which has a throughput of 0.5.

The Intel Intrinsics Guide is an interactive reference tool for Intel intrinsic instructions, which are C style functions that provide access to many Intel instructions - including Intel® SSE, AVX, AVX-512.. __m128i b = _mm_set1_epi32(42); __m128 a = b; // NO, only works in LDC __m128 a = cast(__m128)b; // YES, works in all D compilers This is because D does not allow user-defined implicit conversions, and core.simd might be emulated (DMD). Use this cast, or your code won't work in every D compiler variation. add a comment | 2 Answers 2 Active Oldest Votes 0 Because the vector operations (which the #pragma novector precludes) are designed for floating-point values. If you are using integers, you add the steps of converting between the two types.

When I run the shown code, i get the time 3403 ms, If i add #pragma novetor, then time is 6934 ms, i.e. speedup is only 2 times. But if i change the type of all arrays to double, then time is 2067 ms and 7479 ms, respectively, i.e. SIMD-speedup is more than 3.5 times. Why is this happening? Why with integer types such small speedup?
