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.

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)]

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. Examples: "A10-PyTorch-1, xxx". 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. 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.

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".

--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.

For guidance on mapping tests to stage names, see docs/source/reference/ci-overview.md
and the scripts/test_to_stage_mapping.py helper.

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)
Check name Status Explanation Resolution
Description Check ⚠️ Warning The PR description is essentially the repository template with no populated Description or Test Coverage sections and therefore does not explain why the Qwen3 tests were moved, which specific tests were added or removed, or how to validate the change; this omission prevents reviewers from assessing scope and test adequacy despite the raw summary showing edits to jenkins/L0_Test.groovy and l0_b200.yml. Please replace the template with a concise Description that explains the rationale for moving Qwen3 tests and lists the modified files and key test names, add a Test Coverage section enumerating the added/removed tests and describing how to validate them (which CI stages or commands to run), and confirm checklist items such as CODEOWNERS updates or whether a pipeline run is requested.
✅ Passed checks (2 passed)
Check name Status Explanation
Title Check ✅ Passed The title "[None][ci] move qwen3 tests from GB200 to B200" is concise and directly summarizes the primary change in the changeset—moving Qwen3 tests between CI configs—matching the modified files (jenkins/L0_Test.groovy and tests/integration/test_lists/test-db/l0_b200.yml) and following the repository's ticket/type pattern. It is specific enough for a reviewer scanning history to understand the main intent without extraneous detail.
Docstring Coverage ✅ Passed No functions found in the changes. Docstring coverage check skipped.

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

  • Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
  • Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

Timestamp: 2025-07-28T17:06:08.621Z
Learning: In TensorRT-LLM testing, it's common to have both CLI flow tests (test_cli_flow.py) and PyTorch API tests (test_llm_api_pytorch.py) for the same model. These serve different purposes: CLI flow tests validate the traditional command-line workflow, while PyTorch API tests validate the newer LLM API backend. Both are legitimate and should coexist.

Timestamp: 2025-09-09T09:40:45.658Z
Learning: In TensorRT-LLM test lists, it's common and intentional for the same test to appear in multiple test list files when they serve different purposes (e.g., llm_function_core.txt for comprehensive core functionality testing and llm_function_core_sanity.txt for quick sanity checks). This duplication allows tests to be run in different testing contexts.

Learning: In TensorRT-LLM test configuration files, the test scheduling system handles wildcard matching with special rules that prevent duplicate test execution even when the same tests appear in multiple yaml files with overlapping GPU wildcards (e.g., "*b200*" and "*gb200*").

42-53: Confirm Qwen3 B200 additions and single‑GPU memory fit

  • Targeted tests exist in tests/integration/defs/accuracy/test_llm_api_pytorch.py — TestQwen3_8B (line 2451), test_w4a8_mxfp4 (2535), TestQwen3_30B_A3B (2553), test_nvfp4 (2634), test_w4a16_mxfp4 (2750).
  • Entries added to tests/integration/test_lists/test-db/l0_b200.yml (lines ~41–53); the older TestQwen3_8B::test_fp8_block_scales[latency] remains at line 41 — confirm this is intentional.
  • Repo does not include memory/profile data to confirm Qwen3-30B-A3B fits single‑GPU on b100‑ts2 for the selected precisions/backends — verify by running a short latency smoke with the intended activation_dtype/moe_backend or mark the 30B variants as multi‑GPU if they OOM.

2036-2038: B200 PyTorch split expanded to 3 — cannot verify historical runtimes; confirm capacity & balance

Verification script returned no matching JUnit result files; historical wall times could not be computed.

Change: jenkins/L0_Test.groovy:2036–2038

  • Capacity: ensure b100-ts2 has ≥3 available executors so the three splits can run concurrently without starving other pools (check Jenkins nodes/label pool or autoscale config).
  • Runtimes: confirm per-split average and 95th‑percentile wall time remain within the existing stage timeout. To summarize recent JUnit results locally, run:
python - <<'PY'
import glob,re,statistics
files=glob.glob('**/results*B200_PCIe-PyTorch*.xml',recursive=True)[-30:]
for f in files:
    s=open(f).read()
    times=[float(x) for x in re.findall(r'<testsuite[^>]*time="([0-9.]+)"',s)]
    print("==",f,"==")
    if times:
        times.sort()
        n=len(times)
        p95=times[int(0.95*n)-1] if n>0 else 0
        print(f"sum={sum(times):.2f} count={n} avg={statistics.mean(times):.2f} p95={p95:.2f}")
    else:
        print("no times found")
PY

Return the per-split avg and p95 plus current free executor count for b100-ts2 to re-check.
