Greptile Summary

The PR scales the PyTorch expert-parallel test’s outer subprocess timeout according to the number of launcher passes.

• Adds a helper that counts the launcher’s seven run_pass invocations.
• Retains the configured timeout as a per-pass budget.
• Adds a fixed allowance for launcher overhead.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview
tests/pytorch/distributed/test_ep.py	Updates the EP test harness so its outer timeout reflects the launcher’s sequential pass count; no follow-up-eligible blocking issue was identified.
