摘要

我们通过编译器向量化或汇编代码内联来研究Pentium 4 SIMD指令对Fortran和C版本NAS基准的影响。如果很少函数通常从SIMD操作中获益，那么使用复数或随机数生成器的函数可以有效地加速。

Numerical applications and sub-word parallelism: the NAS benchmarks on a Pentium 4

We examine the impact of Pentium 4 SIMD instructions on the Fortran and C versions of the NAS benchmarks, either by compiler vectorization or by assembly code in-lining. If few functions generally profit from the SIMD operations, the ones using complex numbers or random number generators can be efficiently accelerated.
