WalkthroughThe L0 merge pipeline now validates test lists with CPU-only dependencies. The validation script can skip TensorRT-LLM wheel installation, and integration test collection uses fallback values when TensorRT-LLM is unavailable. ChangesTest-list validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR changes test-list validation and setup paths; the no-wheel path currently depends on a missing requirements file, and the fallback can hide failures from an installed package, causing CI to fail early or skip coverage.

Add type annotations to the modified functions.
Use -> bool for ipc_nvls_supported, -> int for get_mpi_world_size, and annotate install_python_dependencies as def install_python_dependencies(llm_src: str, install_wheel: bool = True) -> None:.
This keeps the changed helpers compliant with the repository's function-annotation guideline.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not mask import failures from an installed TensorRT-LLM package.
Catch only ModuleNotFoundError for tensorrt_llm or its missing build-time submodule. The current ImportError handler also catches errors raised inside an installed module. The fallback then reports NVLS as unsupported and MPI size as 1, so CI can silently skip coverage instead of reporting a broken installation.

Accept exit code 2 (collection warnings) alongside 0; any other non-zero code is still a hard failure.

Three things beyond the inline notes. The first one is new since this branch was cut.
Please rebase — #17975 landed on main today and changes what this stage has to do. #17975 rewrote a large part of scripts/check_test_list.py and changed the existing Check Test List invocation in jenkins/L0_Test.groovy to:
check_test_list.py --l0 --qa --waive --validate --parity
Your branch is based on the pre-merge file (head is from Aug 20), so as written the new CPU stage runs a strictly weaker command than the stage it's meant to replace — no --validate, no --parity. Both of those are pure-AST/set logic with no wheel or GPU requirement, so they should run in the CPU pod too; please add them to checkTestList().
More importantly, --continue-on-collection-errors breaks the premise the new --parity gate rests on. load_collectable_entries() reads l0_test.txt / qa_test.txt and treats every entry in them as proven collectable. That claim is only true because verify_l0_test_lists / verify_qa_test_lists run pytest --co with check=True — the files themselves are just the cleaned input lists, not the collected node IDs. Once collection errors are tolerated, those files still contain every entry, so compute_parity() computes false_confidence = accepted − collectable over a set that was never validated. Result: false_confidence is empty, the gate prints PARITY OK: N statically-verified param IDs all collectable, and it is asserting nothing. That's a silent regression of a gate that just merged, and it's worse than the stage being slow. Please either make the CPU path emit the actual collected node IDs (so l0_test.txt keeps meaning what parity assumes), or leave --parity on the wheel-installed stage.
Title says "Move", but nothing was removed. launchTestListCheck in jenkins/L0_Test.groovy:3806 still runs the check on an A10 pod after the build, so it now runs twice. Given the point above, the two invocations are also no longer equivalent. Is the old stage removed in a follow-up, or is the duplication intentional during a bake-in period? Please say which in the description.
Does the CPU-only check still validate anything? modify_by_test_list computes invalid entries as test-list names − collected node IDs. Modules that fail to import (common.py, accuracy/accuracy_core.py and ~40 others import tensorrt_llm at module scope) contribute no node IDs, so every list entry pointing into them should land in invalid_tests.json and fail the stage. Since the commit history says ImportErrors are expected here, please post the stage log showing how many tests were collected and that invalid_tests.json is empty — otherwise the check either fails spuriously or passes vacuously.
Also worth stating the cost: preparation() is serial and gates the build, so apt+pip+full L0 collection is added to every pipeline's startup. How much wall-clock does it add?

The exit-code mapping is backwards. Verified with pytest 9.0.3:
pytest --co -q -> 2 (INTERRUPTED)
pytest --co -q --continue-on-collection-errors -> 1 (TESTS_FAILED)
Collection errors bump session.testsfailed; --continue-on-collection-errors only suppresses the Interrupted raise, so the run ends as TESTS_FAILED (1). Exit 2 is what you get without the flag — and also on a real interrupt (KeyboardInterrupt, shouldstop). As written this still fails on the case you meant to tolerate, and silently passes an aborted run.
Same in verify_qa_test_lists and verify_waive_list. If you do want to tolerate collection errors, key off something explicit (parse the --co output, or check invalid_tests.json) rather than an exit code that means "some tests failed".
Note also that #17975 has since landed on main and made this check=True meaningful beyond this function: load_collectable_entries() treats every entry in l0_test.txt/qa_test.txt as collectable because these three calls hard-fail otherwise. Relaxing them here makes --parity compare accepted against a set that includes uncollectable entries, so false_confidence is always empty and the gate passes vacuously. Please rebase and decide explicitly how the CPU path interacts with --parity (see the review comment).

After the rebase onto current main, this is missing --validate --parity — launchTestListCheck in jenkins/L0_Test.groovy:3823 now runs --l0 --qa --waive --validate --parity (added by #17975). Neither flag needs a wheel or a GPU: --validate is an AST walk over the test sources and --parity is set logic over the lists this run already produced, so both belong in the CPU pod.
They do depend on the collection results being trustworthy, though, so this can't just be flag-copied — see the check_test_list.py comment about --continue-on-collection-errors.

This fallback applies to every pytest run of the integration suite, not just the CPU-only collection pod. In a real test job with a half-broken install, the import now succeeds silently and get_mpi_world_size() returns 1 — so multi-GPU tests at conftest.py:1544 get skipped instead of erroring, and skip_no_nvls skips everything. A silently-green run is worse than an ImportError.
Gate it on something the collection-only path sets explicitly, e.g.
if os.environ.get("TRTLLM_TEST_LIST_CHECK_ONLY") == "1":
def get_mpi_world_size(): return 1
...
else:
from tensorrt_llm.bindings import ipc_nvls_supported
...and export it from checkTestList() in jenkins/L0_MergeRequest.groovy.

There was a problem hiding this comment.
--extra-index-url adds the CPU channel alongside PyPI; pip then resolves torch by version across both indexes and will usually pick the default-PyPI wheel, which is the CUDA build. So the "avoids the ~2 GB CUDA download" comment likely doesn't hold. Use --index-url https://download.pytorch.org/whl/cpu (with the pytest/psutil deps coming from a separate --extra-index-url to PyPI), or pin torch==<ver>+cpu explicitly.
Separately, torch>=2.12.0 floats free of the pinned version in requirements.txt; a future torch release can break this pod without any change in the repo.
