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

The Jenkins test orchestration removes Docker-on-node execution in favor of Kubernetes-only pods, simplifies the launchTestJobs API, revises GPU argument derivation and logging, augments hardware introspection, hardens Slurm output handling, and adds targeted Docker error filtering. The Slurm runner expands GPU diagnostics by chaining multiple nvidia-smi commands.

Changes

Cohort / File(s) Summary of changes
Jenkins pipeline orchestration
jenkins/L0_Test.groovy
Consolidate all sanity/test runs to Kubernetes pods; remove dockerNode path. Update public API: launchTestJobs(pipeline, testFilter). Rework GPU arg construction from NV_GPU/CUDA_VISIBLE_DEVICES into dockerArgs with final logging. Add system/GPU introspection commands. Harden hostname resolution. Wrap Docker operations with selective error ignore. Improve Slurm output handling by replacing %j with real job ID. Enable GB200-PyTorch-1 in SBSASlurmTestConfigs.
Slurm diagnostics
jenkins/scripts/slurm_run.sh
Replace single nvidia-smi with chained: nvidia-smi && nvidia-smi -q && nvidia-smi topo -m within SLURM_LOCALID==0 block.

🧹 Nitpick comments (4)
jenkins/scripts/slurm_run.sh (1)

25-25: Don’t fail the whole run on optional GPU topology query.

nvidia-smi topo -m can fail on some stacks; chaining with && aborts the job prematurely. Make each probe non-fatal.

-    nvidia-smi && nvidia-smi -q && nvidia-smi topo -m
+    { nvidia-smi || true; } && { nvidia-smi -q || true; } && { nvidia-smi topo -m || true; }
jenkins/L0_Test.groovy (3)

363-363: Make GPU diagnostics best-effort to avoid aborting stages.

As in the Slurm script, chaining with && makes the whole step fail if any one probe fails. Prefer non-fatal probes.

-sh "nvidia-smi && nvidia-smi -q && nvidia-smi topo -m"
+sh "{ nvidia-smi || true; } && { nvidia-smi -q || true; } && { nvidia-smi topo -m || true; }"

Also applies to: 1047-1047, 1456-1456, 1832-1832


188-191: Ensure destination path exists when renaming %j log.

If ${slurmOutputFile} includes subdirs that differ once %j is replaced, mv can fail. Create the destination dir first.

-            def newSlurmOutputFile = slurmOutputFile.replace("%j", slurmJobID)
-            Utils.exec(pipeline, script: Utils.sshUserCmd(remote, "\"mv ${slurmOutputFile} ${newSlurmOutputFile} || true\""))
+            def newSlurmOutputFile = slurmOutputFile.replace("%j", slurmJobID)
+            def newDirCmd = "mkdir -p \\\"$(dirname ${newSlurmOutputFile})\\\""
+            Utils.exec(pipeline, script: Utils.sshUserCmd(remote, "\"${newDirCmd} && mv ${slurmOutputFile} ${newSlurmOutputFile} || true\""))

966-973: Hostname fallback robustness.

Add a final fallback to hostname in case -f isn’t configured.

-    String hostNodeName = sh(script: '''
+    String hostNodeName = sh(script: '''
         if [ -n "$HOST_NODE_NAME" ]; then
             echo "$HOST_NODE_NAME"
         else
-            hostname -f
+            hostname -f || hostname
         fi
     ''', returnStdout: true).trim()

Learning: In TensorRT-LLM, examples directory can have different dependency versions than the root requirements.txt file. Version conflicts between root and examples dependencies are acceptable because examples are designed to be standalone and self-contained.

🔇 Additional comments (5)
jenkins/L0_Test.groovy (5)

157-162: Broadened Slurm job ID parsing looks good.


1886-1902: Benign Docker kill errors are correctly suppressed.


2068-2071: Add mapping for GB200-PyTorch-2 or update references
Only “GB200-PyTorch-1” is defined in jenkins/L0_Test.groovy (lines 2068–2071 and 2075–2085), but recent runs reference “GB200-PyTorch-2”. Add the sibling stage for “-2” with the appropriate config or remove/update any “-2” references.


1919-1919: Signature change ripple-check passed. No remaining calls to launchTestJobs with three arguments found.


351-379: Remove unused dockerGpuOption or rename to match the used dockerGPUOption—no runtime break

Likely an incorrect or invalid review comment.
