I've used joblib before and it does some nice things like make it easy to switch between different backends (loky, multiprocessing, threading) but recently I've started to use python's new-ish built-in way: ThreadPoolExecutor if IO-bound ProcessPoolExecutor if CPU-bound for example from concurrent.futures import ThreadPoolExecutor with ThreadPoolExecutor(max_workers=4) as e: e.submit(shutil.copy, 'src1.txt', 'dest1.txt') e.submit(shutil.copy, 'src2.txt', 'dest2.txt') print("everything done!")
