Summary of Changes
Hello @chenyushuo, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request adds essential documentation for the 'Synchronizer' module in the Trinity-RFT framework. The new document provides a detailed explanation of how the Synchronizer facilitates efficient and stable distributed reinforcement learning by managing the synchronization of model weights between the Trainer and Explorer components. It covers various synchronization methods and styles, state management, and offers practical advice on choosing the appropriate configurations for different distributed environments, significantly improving the clarity and usability of the system's distributed training capabilities.
Highlights
- New Synchronizer Documentation: This PR introduces comprehensive documentation for the 'Synchronizer' module within Trinity-RFT, explaining its critical role in coordinating the Trainer and Explorer components in distributed reinforcement learning environments.
- Synchronization Methods Explained: The documentation details three distinct methods for weight synchronization: NCCL (for direct GPU-to-GPU), MEMORY (for shared memory/network), and CHECKPOINT (for disk-based transfer), providing guidance on their optimal use cases.
- Synchronization Styles Defined: It clarifies two synchronization styles: 'FIXED' for regular, interval-based updates and 'DYNAMIC_BY_EXPLORER' for demand-driven synchronization, allowing flexibility based on data generation needs.
- State Management and Transitions: The new document also covers the state management within the Synchronizer, illustrating how different states (STOPPED, RUNNING, REQUIRE_SYNC, WAITING_SYNC) ensure smooth and safe coordination between components.

Code Review
This pull request adds comprehensive documentation for the Synchronizer component. The new markdown file explains its purpose, architecture, different synchronization methods and styles, and state management. My review focuses on improving the clarity, grammar, and tone of the new documentation to ensure it is easy for users to understand. I've suggested several minor text changes to correct grammar and improve readability throughout the document.
