Suggestios:
Consider logging the invalid world_size before raising the ValueError, which might help with debugging in production environments.
Ensure unit tests are updated or added for single-GPU, multi-GPU, and invalid world_size cases.
Overall, this is a clean and helpful refactor. Great job!

Adds a simple check to ensure world_size is valid (>=1), and cleans up the logic for handling single vs multi-process cases in forward(). Prevents possible errors and makes the code easier to follow.
