如何编写C++代码简单测试一下x86和arm的CPU性能

2022-08-10 15:35:30 浏览数 (1)

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：

代码语言：javascript复制
int main() {
    int i;
    for (i = 0; i < 10000000; i  ) { }
    return (0);
}

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 

x86

arm

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：

代码语言：javascript复制
#include<iostream>
#include<cstdio>
#include<cmath>
#include<vector>
using namespace std;
const long long N = 1e8;
int main(){
    double m_pi=M_PI;
    for(long long i=1;i<N;i  )
    {
        m_pi=m_pi*i/123456;
    }
    cout<<m_pi<<endl;
    return 0;
}

 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？

代码语言：javascript复制
#include<iostream>
#include<cstdio>
#include<cmath>
#include<vector>
using namespace std;
const long long N = 8e8;
int main(){
    double m_pi=M_PI;
    for(long long i=1;i<N;i  )
    {
        m_pi=m_pi*i/1.23456;
    }
    cout<<m_pi<<endl;
    return 0;
}

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：
