A simple multiprocessing function pool

Project description

pytaskpool (v1.5)

A simple multiprocess function pooler which create results generators

pytaskpool use the python multiprocessing module

pytaskpool provide an easy way to execute python functions in a pool of process (not threads) for using all your CPU cores. Functions results can then be then obtained in order or not (via a generator method).

pytaskpool works on windows and linux.

Source code & Development:



pytaskpool is available in the python index package (pip), It can be installed running the following command:

$ pip install pytaskpool

or by git like this:

$ git clone
$ cd pytaskpool
$ sudo python install

or even in a zip over http :


This sample code will simultanously launch 8 functions with differents parameters using a pool of 8 processes. The results returned by all launched functions will be get by the method get_sorted_results(), which is a generator returning the functions results in order.

The excepted execution time should be around 1 second.

Sample code:

import pytaskpool as tp
from time import sleep

def my_func(x):
    return x ** x

mypool = tp.TaskPool(8)

for r in range(8):
    mypool.launch(my_func, r)

unsorted = [r for r in mypool.get_unsorted_results()]
sorted = [r for r in mypool.get_sorted_results()]

print ("unsorted :",unsorted)
print ("sorted   :",sorted)

Terminal output should look like this:

$ time python examples/
unsorted : [1, 1, 4, 27, 256, 46656, 3125, 823543]
sorted   : [1, 1, 4, 27, 256, 3125, 46656, 823543]

real    0m1,055s
user    0m0,800s
sys     0m0,272s
