## Summary of Changes Hello @Dayuxiaoshui, I'm Gemini Code Assist[^1]! 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 significantly improves the stability and resilience of the `MetaSchedule` tuning process. It specifically targets and resolves a critical crash that occurred when the `RewriteParallelVectorizeUnroll` postprocessor encountered un-schedulable blocks, such as those with conflicting read/write operations on the same buffer. By introducing robust exception handling within both the postprocessor itself and the `ThreadedTraceApply` utility, the system can now gracefully manage and log these scheduling failures, allowing the tuning session to continue without interruption, thereby enhancing the overall user experience and reliability. ### Highlights * **Crash Fix**: Addresses a crash in `meta_schedule.tune_tir` during initial population sampling. * **Root Cause**: The crash was due to `RewriteParallelVectorizeUnroll` encountering blocks that violate compact dataflow requirements, specifically when a block reads and writes to the same buffer, leading to a `ScheduleError`. * **Solution in Postprocessor**: Implemented `try-catch` blocks in `RewriteParallelVectorizeUnroll::Apply` to catch `ScheduleError` and skip problematic blocks, preventing crashes. * **Robustness in Utility**: Added broader exception handling in `ThreadedTraceApply::Apply` to catch any `ScheduleError` or `std::exception` from postprocessors, treating them as graceful failures instead of crashes. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
