Nettet2 dager siden · Modified today. Viewed 35 times. 1. I was wondering what the most efficient way is to extract a single double element from an AVX-512 vector without spilling it, using intrinsics. Currently i'm doing a masked reduce add: double extract (int idx, __m512d v) { __mmask8 mask = _mm512_int2mask (1 << idx); return … NettetIntel SIMD Extensions • MMX 64-bit registers, reusing floating-point registers [1992] ... {PS} Packed Single precision FP: four 32-bit operands in a 128-bit register {SD} Scalar Double precision FP: one 64-bit operand in a 128-bit register {PD} Packed Double precision FP, or two 64-bit operands in a 128-bit register {A} ...

Nettet4.10 SIMD向量处理 我们之前介绍了一种并行化，SIMD。 可以一条指令并行处理多个数据，SIMD和多线程可以合并为一种并行类型叫SIMT (single instruction multiple thread)。 Intel 1994年率先给出了MMX指令,允许8条8位整型或者4个16bit或者两个32bit的计算打包到一条特殊的64bit MMX寄存器中。 Intel接下来进行了一系列修改，给出扩展指令 … NettetOn Intel mainstream CPUs (not Atom/Silvermont) these are somewhat faster than doing it manually with multiple instructions.

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？
