Was playing around with Python for a second there. I learnt about one of the new “multiprocessing” features. Its pretty standard stuff, but thankfully does what I actually wanted Python to always do. Allow me to multiprocess any Map function. Below is the sample code (2.6 and above only sorry).

from multiprocessing import Pool
import time

def f(x):
  return x*x

if __name__ == '__main__':
  p = Pool(processes=2)
  r = range(1,10000000)
  t = time.time(),r)
  print time.time()-t
