To enable SIMD, pass the -msimd128 flag at compile time. This will also turn on LLVM’s autovectorization passes, so no source modifications are necessary to benefit from SIMD. At the source level, the GCC/Clang SIMD Vector Extensions can be …
Nettet29. mai 2011 · Both Intel and AMD have some sort of vector math library with SIMD sines and cosines, but Intel MKL is not free (neither as beer, nor as speech) AMD ACML is free, but no source is available. Morever the vector functions are only available in 64bits OSes ! Would you trust the intel MKL to run at full speed on AMD hardware ? Nettet鑒於_mm256_sqrt_ps()相對較慢，並且我正在生成的值立即被_mm256_floor_ps()截斷，環顧四周似乎在這樣做： _mm256_mul_ps(_mm256_rsqrt_ps(eightFloats), eightFloats); 是獲得額外性能並避免流水線停滯的方法。 不幸的是，使用零值時，我當然會崩潰計算1/sqrt(0) 。 最好的辦法是什么？
