cpu_usage 100% In centos

[eheroqiu]

When I use scoop in centos, no matter how many do I set the number of -n ,My cpu usage is 100%, but cpu load is very normal in macos. ps. My centos machine is 40 cores

how does it happened?

from math import hypot from random import random from scoop import futures import time

def test(tries): return sum(hypot(random(), random()) < 1 for _ in range(tries))

def calcPi(nbFutures, tries): expr = futures.map(test, [tries] nbFutures) return 4. sum(expr) / float(nbFutures * tries)

if name == "main": nbFutures = 3000 tries = 5000

bt = time.time()

# Divide the work among fewer processes to minimize overhead
chunk_size = 10
expr = futures.map(test, [chunk_size] * (nbFutures * tries // chunk_size))

print("pi = {}".format(4. * sum(expr) / float(nbFutures * tries)))
print('time:', time.time() - bt)
