Python thread pool similar to the multiprocessing Pool?
- by Martin
Is there a Pool class for worker threads, similar to the multiprocessing module's Pool class?
I like for example the easy way to parallelize a map function
def long_running_func(p):
c_func_no_gil(p)
p = multiprocessing.Pool(4)
xs = p.map(long_running_func, range(100))
however I would like to do it without the overhead of creating new processes.
I know about the GIL. However, in my usecase, the function will be an IO-bound C function for which the python wrapper will release the GIL before the actual function call.
Do I have to write my own threading pool?
