Golang : Get number of CPU cores
Problem :
You want to find the maximum number of CPU cores to maximize performance.
Solution :
Use the runtime package to find out the number of CPU cores available on local machine.
package main
import (
"fmt"
"runtime"
)
func main() {
cores := runtime.NumCPU()
fmt.Printf("This machine has %d CPU cores. \n", cores)
// maximize CPU usage for maximum performance
runtime.GOMAXPROCS(cores)
}
