Summary of Changes

Hello @meichangsu1, 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 refines the project's documentation and an example script. It improves the clarity of the README by separating combined entries for FSDP MoE finetuning, making it easier for users to navigate. Additionally, it cleans up an example script by removing an unnecessary parameter from a device mesh configuration, streamlining the code.

Highlights

• README Clarity: The "ep/sp FSDP MoE finetuning" entry in the README has been split into two distinct entries: "ep FSDP MoE finetuning" and "sp FSDP finetuning", enhancing documentation clarity.
• Code Cleanup: The ulysses_size parameter and its associated variable have been removed from the DeviceMesh initialization in ep_fsdp_qwen3_moe.py as it is no longer required for the example configuration.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request updates the documentation and an example script. In README.md, the combined 'ep/sp FSDP MoE finetuning' entry is split into two separate entries for clarity. In ep_fsdp_qwen3_moe.py, the ulysses_size parameter is removed, which correctly reflects that this example is no longer for sequence parallelism. The changes are good and improve clarity. I've added one comment to improve the formatting of the table in README.md.
