| Single Controller interface | |
| ============================ | |
| Last updated: 05/27/2025 (API docstrings are auto-generated). | |
| The Single Controller provides a unified interface for managing distributed workers | |
| using Ray or other backends and executing functions across them. | |
| It simplifies the process of dispatching tasks and collecting results, particularly | |
| when dealing with data parallelism or model parallelism. | |
