并行化python for循环 [英] Parallelize python for-loop

问题描述

我想使用带有2个四核处理器的Mac Pro并行化以下python循环.

I would like to parallelize the following python loop using a Mac Pro with 2 Quad-Core processors.

result_list = []
for a in a_range:
    for b in b_range:
        for c in c_range:
            result = call_fortran_program(a, b, c)
            result_list.append(result)

在搜索中，我遇到过Cython和GIL之类的词，但我仍不清楚如何进行.

In my searches I've run across terms like Cython and GIL but it's still not clear to me on how to proceed.

推荐答案

from itertools import product
from multiprocessing import Pool

with Pool(processes=4) as pool:  # assuming Python 3
    pool.starmap(print, product(range(2), range(3), range(4)))
