Summary by CodeRabbit

  • Tests
    • Enabled a previously inactive GB200 PyTorch SBSA Slurm test with a single split and default GPU count.
    • Removed multiple Qwen PyTorch pre-merge tests and added GPTOSS w4 1‑GPU checks for cutlass, trtllm, and triton.
    • Cleared PyTorch pre-merge entries and removed post-merge blocks for TensorRT, Triton, and PyTorch in GB200 test lists.
  • Chores
    • CI test matrix cleanup to focus coverage and reduce redundant entries.

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.

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.

📝 Walkthrough

Walkthrough

Enables the GB200-PyTorch-1 entry in the SBSA Slurm Jenkins matrix (now active with splits=1) and updates test lists: removes many Qwen and other PyTorch entries from l0_gb200.yml, and in l0_b200.yml removes several Qwen tests and adds three GPTOSS test_w4_1gpu entries.

Changes

Cohort / File(s) Summary
Jenkins SBSA Slurm matrix
jenkins/L0_Test.groovy
Activates GB200-PyTorch-1 in SBSASlurmTestConfigs, changing its entry to ["gb200-single", "l0_gb200", 1, 1] (single split, default GPU count). Also adjusts B200 PyTorch entries: B200_PCIe-PyTorch-1 from 1,31,2, B200_PCIe-PyTorch-2 from 2,32,2, and removes B200_PCIe-PyTorch-3.
B200 pre_merge test list adjustments
tests/integration/test_lists/test-db/l0_b200.yml
Removes multiple Qwen PyTorch pre_merge entries (e.g., TestQwen3_8B, TestQwen3_30B_A3B) and adds three GPTOSS test_w4_1gpu entries for backends cutlass, trtllm, and triton.
GB200 test list removal
tests/integration/test_lists/test-db/l0_gb200.yml
Deletes all listed PyTorch pre_merge tests and removes the post_merge blocks for tensorrt, triton, and pytorch. No additions.

1924-1924: GB200-PyTorch-1 Single-GPU Split & Qwen3 Tests Migration Verified
Confirmed that the GB200-PyTorch-1 entry in jenkins/L0_Test.groovy (line 1924) now uses the “gb200-single” 1/1 split, and that all Qwen3 tests live in tests/integration/test_lists/test-db/l0_gb200.yml with none remaining in l0_b200.yml. Nice catch—approving these changes.


1823-1824: B200 single-GPU splits reduced correctly with no orphaned “-3” references

All guard checks passed:

  • jenkins/L0_Test.groovy defines only “B200_PCIe-PyTorch-1” and “B200_PCIe-PyTorch-2”, with no occurrences of “B200_PCIe-PyTorch-3”.
  • tests/integration/test_lists/test-db/l0_b200.yml contains no “qwen” entries.

No further action required.

1925-1929: Fix misleading comment and consider making gpuCount explicit

  • The “Not used in the pipeline now” comment is misleading: SBSASlurmTestConfigs is consumed when env.targetArch == AARCH64_TRIPLE. Update the comment to reflect actual usage.
  • Minor: Explicitly setting gpuCount=1 makes intent future-proof and consistent with other entries that pass GPU count.

Suggested diff:

 SBSASlurmTestConfigs = [
-    // Not used in the pipeline now
-    "GB200-PyTorch-1": ["gb200-single", "l0_gb200", 1, 3],
+    // SBSA Slurm stages; executed when env.targetArch == AARCH64_TRIPLE
+    "GB200-PyTorch-1": ["gb200-single", "l0_gb200", 1, 3, 1],
     "GB200-4_GPUs-PyTorch-1": ["gb200-x4", "l0_gb200_multi_gpus", 1, 1, 4],

1926-1926: LGTM on wiring GB200 single-GPU PyTorch to SBSA Slurm path

Stage name, platform key, and test-db context align with runLLMTestlistOnSlurm() signature and mako arg derivation. With the split coverage concern addressed, this looks good.
