Summary of Changes

Hello @BBuf, 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 significantly enhances the CI monitoring capabilities by introducing a "Test Balance Analyzer." This new tool is designed to identify and address inefficiencies in the CI pipeline by analyzing the time differences between actual test execution and their estimated durations, specifically for GPU-related tests. By providing detailed reports and actionable recommendations, it aims to prevent CI timeouts and optimize resource allocation. Alongside this, the existing CI failure analyzer has been streamlined for better focus and readability.

Highlights

• New CI Monitor Tool: Introduced ci_analyzer_balance.py, a new script to monitor and analyze test time balance in CI.
• Test Time Gap Analysis: The new tool identifies significant discrepancies between elapsed and estimated test times, focusing on GPU jobs within the pr-test.yml workflow.
• CI Optimization: It helps optimize CI by tracking maximum time gaps, ranking tests by severity, and providing recommendations for adjusting estimated test durations.
• Reporting and Integration: The tool generates detailed JSON and CSV reports and integrates with GitHub Actions to provide summaries and actionable insights.
• ci_analyzer.py Refinement: The existing ci_analyzer.py script has been updated to remove verbose comments and explicitly define the target CI jobs for analysis, improving clarity and maintainability.
• Documentation Update: README.md has been updated to include the new Test Balance Analyzer, its features, dependencies, and usage instructions.

Code Review

This pull request introduces a new CI analysis tool, ci_analyzer_balance.py, to monitor test time balance, which is a valuable addition for maintaining CI efficiency. The new script is well-structured, but there are several opportunities for improvement, such as removing dead code and unused variables, and adhering to Python best practices like placing imports at the top of the file.

Additionally, ci_analyzer.py has been refactored. The move to a whitelist for job filtering is a good improvement for clarity. However, the removal of all docstrings from the file significantly reduces its maintainability. I've added comments with suggestions to address these points.
