gocpuload

gocpuload

Usage:

as CLI

example 01: run 30% of all CPU cores for 10 seconds

gocpuload -p 30 -t 10

example 02: run 30% of all CPU cores forver

gocpuload -p 30

example 03: run 30% of 2 of CPU cores for 10 seconds

gocpuload -p 30 -c 2 -t 10

• all CPU load = (num of para c _ num of p) / (all cores count of CPU _ 100)
• may not specify cores run the load only, it just promise the all CPU load, and not promise each cores run the same load

CLI Parameters

--coresCount value, -c value   how many cores (optional, default: 8)

--timeSeconds value, -t value  how long (optional, default: 2147483647)

--percentage value, -p value   percentage of each specify cores (required)

--help, -h                     show help

as Liblary

import (
	"context"
	"github.com/0Delta/gocpuload"
)

func main(){
    ctx := context.Background()
    // RunCPULoad(ctx context.Context, coresCount int, timeSeconds int, percentage int)
    //
    // This function return control immediately.
    loadCtx, loadCancel := gocpuload.RunCPULoad(ctx, runtime.NumCPU()/2, 3, 80)

AdvancedUseage:
    // If you want wait loading, use below.
    <-loadCtx.Done()

    // You can cancel loading before appoint time.
    loadCancel()

}

Requirements:

• go

for test in Windows

• cgo

Install:

• go1.6 or higher

go install github.com/0Delta/gocpuload@latest

• go1.5 or lower

go get -u github.com/0Delta/gocpuload

How it runs:

• Giving a range of time(e.g. 100ms)
• Want to run 30% of all CPU cores
  • 30ms: run (CPU 100%)
  • 70ms: sleep(CPU 0%)
