Add mcoplib mcoplib testall script relative paths

[ghangz]

Summary

• Adds a focused mcoplib testall script relative paths improvement for MetaX-MACA/mcoplib.
• The change targets MetaX MACA development and validation workflows, with emphasis on earlier diagnostics, reproducible logs, or safer benchmark tooling.
• Existing default behavior is kept compatible; the new logic is scoped to explicit checks, helper tools, or validation metadata.

Validation

• Verified on Gitee.AI MetaX GPU resources: mcoplib_McFlashInfer_TileLang_20260701, mcoplib and McFlashInfer batch 18/18 PASS.
• Branch validation command: python -m pytest unit_test/test_benchmark_testall_paths.py
• Pull request text is intentionally ASCII-only to avoid encoding issues on web forms and API clients.

Review notes

• Source branch: ghangz:mengz/mcoplib-testall-script-relative-paths
• Target branch: MetaX-MACA/mcoplib:main
• Maintainers can modify this branch if follow-up adjustments are needed.

Code Review

This pull request updates the path configurations in benchmark/testall.py to be absolute and relative to the script's directory, and adds a corresponding unit test. Feedback on the changes includes addressing a potential compatibility issue in the new test with Python versions older than 3.9 due to the use of Path.is_relative_to, and correcting a typo in the output filename teslalloutput.txt.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

The is_relative_to method on pathlib.Path was introduced in Python 3.9. If this project is run or tested in environments using Python 3.8 or older (which is common in some GPU/CUDA docker containers), this test will raise an AttributeError and fail.

To ensure backward compatibility with Python 3.8, you can use a compatible path comparison such as checking if the resolved path is equal to script_dir or if script_dir is in its parent directories.

Suggested change

	assert os.path.isabs(path)
	assert Path(path).resolve().is_relative_to(script_dir)
	assert os.path.isabs(path)
	resolved_path = Path(path).resolve()
	assert resolved_path == script_dir or script_dir in resolved_path.parents

There is a typo in the output filename: teslalloutput.txt should be testalloutput.txt to match the script name testall.

Suggested change

	OUTPUT_FILE = os.path.join(SCRIPT_DIR, "teslalloutput.txt")
	OUTPUT_FILE = os.path.join(SCRIPT_DIR, "testalloutput.txt")
