What is shared memory in multiprocessing?

What is shared memory in multiprocessing?

Shared memory is a method where multiple processes can access the same memory space, allowing for efficient data exchange.

How does it differ from message passing?

Unlike message passing, where data is sent between processes, shared memory allows direct access to a common memory area, reducing overhead.

What are the advantages of using shared memory?

Advantages include faster data access, reduced communication overhead, and the ability to share large data structures easily.

Are there any downsides to using shared memory?

Yes, it can lead to complexity in synchronization and potential issues like race conditions if not managed properly.

Can you give an example of how to implement shared memory in Python?

Sure! You can use the multiprocessing module in Python, specifically Value or Array for shared memory.
