People here mention Pool, and I've seen it many times. It's this: https://docs.python.org/3/library/multiprocessing.html#introduction https://docs.python.org/3/library/multiprocessing.html#intro... from multiprocessing import Pool def f(x): return x*x if __name__ == '__main__': with Pool(5) as p: print(p.map(f, [1, 2, 3])) This forks out up to 5 processes. f(x) runs fully in parallel for each input. The inputs and outputs sent between processes via pickling.
