How Intel® AVX2 Improves Performance on Server Applications

The latest Intel® Xeon® processor E5 v3 family includes a feature called Intel® Advanced Vector Extensions 2 (Intel® AVX2), which can potentially improve application performance related to high performance computing, databases, and video processing. Here we will explain the context, and provide an example of how using Intel® AVX2 improved performance for a commonly known benchmark.

  • Intel® Optimized LINPACK Benchmark 性能测试

    Linpack是我们常用的CPU性能测试程序。它通过计算双精度线性方程组的求解来测试CPU的运算能力。Intel MKL提供一个优化版本的Intel® Optimized LINPACK Benchmark,通过运行这个程序,我们可以方便进行CPU的基准性能测试。

    Intel® Optimized LINPACK Benchmark是根据LINPACK 1000 benchmark优化后的程序。程序根据用户指定的参数生成一个线性的方程组,通过方程的求解时间与计算量,来计算CPU的浮点性能。
