• 如何编写C++代码简单测试一下x86和arm的CPU性能

    x86：Intel(R) Core(TM) i5-8250U CPU

    arm：Qualcomm ® snapdragon ™ 821（MSM8996-AC）

    一千万次nop循环c代码如下：

    1. int main() {
    2.     int i;
    3.     for (i = 0; i < 10000000; i++) { }
    4.     return (0);
    5. }

    编译和执行，如下：

    gcc noploop.c -o noploop 

    time ./noploop

    这种方式只能大概测试，并不十分精确^_^

    左x86，右arm 

    x86arm
    一千万次real    0m0.029s
    user    0m0.028s
    sys     0m0.002s    		real    0m0.126s
    user    0m0.093s
    sys     0m0.013s
    八千万次real    0m0.135s
    user    0m0.135s
    sys     0m0.000s    		real    0m0.523s
    user    0m0.487s
    sys     0m0.013s

    运算性能：

    1. #include
    2. #include
    3. #include
    4. #include
    5. using namespace std;
    6. const long long N = 1e8;
    7. int main(){
    8.     double m_pi=M_PI;
    9.     for(long long i=1;i
    10.     {
    11.         m_pi=m_pi*i/123456;
    12.     }
    13.     cout<
    14.     return 0;
    15. }

     x86：

    real    0m0.654s
    user    0m0.654s
    sys     0m0.000s

    arm：

    real    0m0.948s
    user    0m0.887s
    sys     0m0.020s

    稍微修改一下程序，再测试一下？

    1. #include
    2. #include
    3. #include
    4. #include
    5. using namespace std;
    6. const long long N = 8e8;
    7. int main(){
    8.     double m_pi=M_PI;
    9.     for(long long i=1;i
    10.     {
    11.         m_pi=m_pi*i/1.23456;
    12.     }
    13.     cout<
    14.     return 0;
    15. }

    当然这种代码除了耗电之外，没有任何实际用途！

     

    用到的指令如下：

    •   652  gcc noploop.c -o noploop
    •   653  time ./noploop
    •   654  ls
    •   655  gcc noploop8.c -o noploop8
    •   656  time ./noploop8
    •   657  grep model.name /proc/cpuinfo
    •   658  exit
    •   659  g++ calculateloop.cpp -o calculateloop
    •   660  time ./calculateloop
    •   661  ./calculateloop
    •   662  time ./calculateloop
    •   663  g++ calplusloop.cpp -o calplusloop
    •   664  time ./calplusloop

    如果偏好是自己编写基准工具，在汇编中，然后对编译的机器代码进行反汇编以进行验证。怎么知道CPU实际上在做什么？

    这样做通常是不切实际的，但会尽可能地分享一个案例。这是用于 CPU 基准测试的，将它与其他工具（例如 sysbench、lmbench）和主动基准测试方法一起使用。

    这是使用展开的无操作 (NOP) 循环测量 CPU 时钟速度的过程。它旨在简单，最大限度地减少由缓存未命中、停顿周期和分支预测错误引起的变化。在尝试更复杂的 CPU 基准测试之前，该结果提供了一个基线。

    由于在 Linux 上运行它，只能读取 /proc/cpuinfo，但并不完全信任它在虚拟化环境中（它可以伪造 cpuid）。更信任的一种方法是简单地从 CPU 性能监控单元读取周期计数器（例如，使用 perf），但在虚拟化环境中访问这些计数器的权限有限或无法访问。

    补充

    直接用hardinfo测试更轻松一些：
