| 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. |
