The Go language gets a method for the number of native logical CPU

This example shows how the Go language gets the number of native logical CPU. Share with you for your reference. The specific analysis is as follows:

1 generally speaking, the amount of native logical CPU can be obtained through NumCPU of runtime library, not physical CPU, for example, 1 dual-core CPU with hyper-threading technology would be considered 4 logical CPU

package main

import (

    "runtime"

    "fmt"

)

func main(){

    fmt.Println(runtime.NumCPU())

}

I hope this article has been helpful to you in the programming of Go language.
