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)
