What are some advanced multiprocessing techniques in Python?

Advanced multiprocessing techniques in Python include using the multiprocessing module, process pools, and shared memory.

Can you explain how to use process pools?

Sure! Process pools allow you to manage a pool of worker processes. You can use Pool from the multiprocessing module to create a pool and then use methods like map and apply to distribute tasks.

What about shared memory? How does that work?

Shared memory allows multiple processes to access the same data without copying it. You can use Value or Array from the multiprocessing module to create shared objects.

Are there any performance considerations I should be aware of?

Yes, be mindful of the overhead of inter-process communication and the Global Interpreter Lock (GIL) in Python, which can affect performance.
