People here mention Pool, and I've seen it many times. It's this: 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.
