Invoking CPU Stress

Question

Looking for an app or tool to invoke CPU usage on my virtual Linux and Unix guests. I found the app "stress" from a post on Stackoverflow, but curious what the Unix/Linux crowd would recommend.

Answer 1

The goto for Linux is cpuburn (homepage). I would expect that it should work on other UNIX systems as well.

Answer 2

stress is pretty good. I see no reason to use something else.

Answer 3

I think cpuburn and stress are good, but I also have python script that I use to additional stress.

import multiprocessing
import math

def worker():
    #worker function
    print ('Worker')
    x = 0
    while x < 1000000000000000000:

        print(x)
        p = x*math.pi
        p2 = math.sqrt(x**2 + p**2)
        print(p2)

        x += 1
    return

if __name__ == '__main__':
    jobs = []
    for i in range(50):
        p = multiprocessing.Process(target=worker)
        jobs.append(p)
        p.start()
