在 Go 中测量 FLOPS

Question

我想编写一个 go 程序来对我的 CPU 进行基准测试并计算出我的笔记本电脑的 GFLOPS。

func benchmarkFlopTime(){

    num_operations := int(100000000)

    var timeArray[] time.Duration;

    var result float64

    for i:=0; i < num_operations; i++ {

        t1 := time.Now()

        result = 1.0 + 312.232

        elapsed := time.Since(t1)

        timeArray = append(timeArray, elapsed)

        result += 1.0

    }

    fmt.Println("Result (ns):", float64(sumTimeArray(timeArray))/float64(time.Duration(num_operations)))

}

输出 1：结果 (ns)：9.99604753ns

解释：

这段代码给了我大约0.1 GFLOPS ((1sec/10ns)/10^-9)。我知道我的 CPU 每个周期可以做 8 次操作，而我只做一次，所以我可以有一个因子 8，假设我有1GFLOPS

问题：

虽然，我的笔记本电脑的 GFLOPS 理论数量为 2.5GHZ i7，8 核，应该是： 8*2.5*8 = 160GFLOPS。我远远低于这个结果。

我确切地说我在编译时不激活优化go install -gcflags '-N -l' github.com/golang/cpu-benchmark。

我们能解释一下这个远低于理论值的值吗？Go 可以测量吗？

这是一个（简单的）Go 基准测试，它对一个循环和二十个浮点运算进行计时。package mainimport (&nbsp; &nbsp; "fmt"&nbsp; &nbsp; "math"&nbsp; &nbsp; "runtime"&nbsp; &nbsp; "testing"&nbsp; &nbsp; "time")var (&nbsp; &nbsp; f&nbsp; float64&nbsp;
