Summary by CodeRabbit

  • Tests
    • Added a CI test configuration for PyTorch on DGX H100 with 4 GPUs, covering a GPT Oss variant with a single split; runs as part of the existing PyTorch suite.
  • Chores
    • Updated auto-trigger mapping so changes in the GPT Oss model area will automatically tag and trigger the related tests.

Description

DGX-H100 GPTOSS is not enabled in #6732

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

Adds a DGX_H100 4-GPU PyTorch GPT_Oss test config, adds mako arg injection for stage names containing -GptOss-, and registers an auto-trigger tag mapping for "-GptOss-" tied to tensorrt_llm/_torch/models/modeling_gpt_oss.py. No public signatures were changed.

Changes

Cohort / File(s) Summary of Changes
Jenkins L0 test config
jenkins/L0_Test.groovy
Added x86TestConfigs entry "DGX_H100-4_GPUs-PyTorch-GptOss-1": ["dgx-h100-x4", "l0_dgx_h100", 1, 1, 4] and updated getMakoArgsFromStageName(stageName, ...) to append auto_trigger=gpt_oss when stageName contains -GptOss-.
Auto-trigger tag mapping
jenkins/L0_MergeRequest.groovy
Added mapping "tensorrt_llm/_torch/models/modeling_gpt_oss.py": ["-GptOss-"] to getAutoTriggerTagList's specialFileToTagMap.

1765-1765: LGTM: Stage entry is well-formed and consistent with schema

  • Name segments and ordering align with existing patterns.
  • Platform/yaml match other DGX_H100 entries.
  • GPU count 4 matches type "dgx-h100-x4" and will provision 4 GPUs.

624-633: Harden against null entries in changedFileList

In rare cases, changedFileList can contain nulls (e.g., from API variations), and file.startsWith(...) would NPE. Cheap guard:

-    for (file in changedFileList) {
+    for (def file in changedFileList) {
         for (String key : specialFileToTagMap.keySet()) {
-            if (file.startsWith(key)) {
+            if (file?.startsWith(key)) {
                 autoTriggerTagList += specialFileToTagMap[key]
             }
         }
     }

626-627: Auto-trigger tag mapping for GPT_Oss is correct

The mapping to "-GptOss-" for modeling_gpt_oss.py aligns with the tag-driven trigger mechanism used elsewhere (e.g., DeepSeek). Good addition.


624-627: Cross-file integration verified for “-GptOss-”

All checks pass—no further action required.

  • The modeling file exists at tensorrt_llm/_torch/models/modeling_gpt_oss.py.
  • L0_Test.groovy contains the stageName.contains("-GptOss-") branch.
  • getMakoArgsFromStageName correctly adds auto_trigger=gpt_oss for “-GptOss-”.
  • The DGX_H100-4_GPUs-PyTorch-GptOss-1 test configuration is defined.
