Embarrassingly parallel for loops — joblib 1.3.0.dev0 documentation
WebThe multiprocessing.pool.Pool provides a process pool that allows tasks to be issued and executed in parallel. The pool provides 8 ways to issue tasks to workers in the process pool. They are: Pool.apply () Pool.apply_async () Pool.map () Pool.map_async () Pool.imap () Pool.imap_unordered () Pool.starmap () Pool.starmap_async () WebThe multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine. It runs on both Unix and Windows. philcart
