[https://nvbugs/6577550][chore] Waive TestNemotron3Super120B::test_ctx_dp2_gen_tp4

[yihwang-nv]

Description

accuracy/test_disaggregated_serving.py::TestNemotron3Super120B::test_ctx_dp2_gen_tp4 is currently waived only under the full:B300/ GPU prefix (nvbugs/6577550). The underlying GSM8K accuracy regression is not B300-specific:

Bug	GPU	Evaluated accuracy (threshold 89.497)	Status
6546605	B200 @ d924d9f1	64.594	Closed, "fixed" by #16072
6577550	B300 @ f0dc88f2	26.876	Open, P0

Same test, same failure signature, both categorized Module_Disaggregated serving and marked as regressions. The failure originally surfaced on B200; it was declared fixed by #16072 and has since resurfaced on B300 at an even lower score, so #16072 appears to have masked rather than fixed it. The test has now been observed failing on B200 again.

This PR widens the waive from the full:B300/ prefix to an unprefixed entry so every stage is covered.

Note that simply adding a full:B200/ line would not have been sufficient: parse_test_name in tests/integration/defs/test_list_parser.py only substitutes the stage's test prefix when test_prefix.split('-')[0] appears in the line, so full:B200/ matches B200-* stages but not the DGX_B200-* stages where this test also runs (l0_dgx_b200.yml).

Only test_ctx_dp2_gen_tp4 is affected. The sibling test_auto_dtype parametrizations keep their existing, separately tracked waives.

Test Coverage

Test-list-only change; no product code is touched. The waives.txt duplicate check and the test-list-entry AST validation pre-commit hooks both pass.

🤖 Generated with Claude Code

Dev Engineer Review

• Updated tests/integration/test_lists/waives.txt.
• Replaced the full:B300/ waiver with an unprefixed waiver for test_ctx_dp2_gen_tp4.
• The wider waiver covers both B200 and B300 stages, including DGX_B200-*.
• Sibling test_auto_dtype waivers remain unchanged.
• Waiver duplicate checks and test-list AST validation pass.
• No product code or public API changes exist.

Verdict: sufficient

QA Engineer Review

• Modified tests/integration/test_lists/waives.txt.
• Removed the B300-specific waiver entry.
• Added the unprefixed waiver entry for accuracy/test_disaggregated_serving.py::TestNemotron3Super120B::test_ctx_dp2_gen_tp4.
• No test-db/ or qa/ files changed.
• The waiver targets an existing test and has the required broader stage coverage.

Verdict: needs follow-up because CBTS coverage data is unavailable.

GitHub Bot Help

/bot [-h] ['run', 'kill', 'skip', 'reuse-pipeline'] ...

Provide a user friendly way for developers to interact with a Jenkins server.

Run /bot [-h|--help] to print this help message.

See details below for each supported subcommand.

Details

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental) --high-priority]

Launch build/test pipelines. All previously running jobs will be killed.

--reuse-test (optional)pipeline-id (OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.

--disable-reuse-test (OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.

--disable-fail-fast (OPTIONAL) : Disable fail fast on build/tests/infra failures.

--skip-test (OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx" (OPTIONAL) : Only run the specified test stages. Supports wildcard * for pattern matching (e.g., "*PerfSanity*" matches all stages containing PerfSanity). Examples: "A10-PyTorch-1, xxx", "PerfSanity". The patterns "*", "*Post-Merge*", and "*PerfSanity*", including equivalent escaped or repeated-star forms and their use in comma-separated lists, require the ci: post-merge approved PR label. Note: Does NOT update GitHub check status.

--gpu-type "A30, H100_PCIe" (OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.

--test-backend "pytorch, cpp" (OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.

--only-multi-gpu-test (OPTIONAL) : Only run the multi-GPU tests. Requires the ci: full pre-merge approved label on the PR (ask a member of NVIDIA/trt-llm-ci-approvers). Note: Does NOT update GitHub check status.

--disable-multi-gpu-test (OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.

--add-multi-gpu-test (OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline. Requires the ci: full pre-merge approved label on the PR (ask a member of NVIDIA/trt-llm-ci-approvers).

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline. Requires the ci: post-merge approved PR label applied by an active member of NVIDIA/trt-llm-ci-approvers. The approval label remains in place when new commits are pushed.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Supports wildcard * for pattern matching. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx", --extra-stage "Post-Merge". The patterns "*", "*Post-Merge*", and "*PerfSanity*", including equivalent escaped or repeated-star forms and their use in comma-separated lists, require the ci: post-merge approved PR label.

--detailed-log (OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.

--debug (OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose. Note: Specify exactly one stage in the stage-list parameter to access the appropriate container environment. Note: Does NOT update GitHub check status.

--high-priority (OPTIONAL) : Run the pipeline with high priority. This option is restricted to authorized users only and will route the job to a high-priority queue.

kill

kill

Kill all running builds associated with pull request.

skip

skip --comment COMMENT

Skip testing for latest commit on pull request. --comment "Reason for skipping build/test" is required. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

reuse-pipeline

reuse-pipeline

Reuse a previous pipeline to validate current commit. This action will also kill all currently running builds associated with the pull request. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.
