import multiprocessing
import subprocess,os

def task(item):
        command = "taskset -c {} stress-ng --cpu 1 --cpu-load 30 --timeout 24h".format(item)
        os.system(command)
        


def run():
    for item in range(112):    ####cpu的数量
        p = multiprocessing.Process(target=task,args=(item,))
        p.start()


if __name__ == '__main__':
    run()
