What are some common mistakes in Python parallelism?
Some common mistakes include not using the right parallelism model, improper handling of shared resources, and ignoring the Global Interpreter Lock (GIL).
Can you explain how the GIL affects parallelism in Python?
The GIL allows only one thread to execute at a time in a single process, which can limit the effectiveness of multi-threading for CPU-bound tasks.
What about using multiprocessing instead of threading?
Multiprocessing can bypass the GIL by using separate memory spaces for each process, making it suitable for CPU-bound tasks.
Are there any libraries that can help with parallelism in Python?
Yes, libraries like concurrent.futures
, multiprocessing
, and joblib
can simplify parallel execution in Python.
