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.

📝 Walkthrough

Walkthrough

This pull request updates CI/CD test configuration and initialization scripts. It expands the GPU test matrix in Jenkins with multiple GPU variant entries, refactors SLURM process initialization to consolidate Git configuration, and simplifies Python dependency installation by removing a retry flag.

Changes

Cohort / File(s) Summary
Test Configuration Expansion
jenkins/L0_Test.groovy
Expands Slurm-based SBSA test set with multiple GPU variants (1 and 2 GPUs) for GB200, PyTorch, and DGX B200/B300 configurations, replacing single entries with corresponding multi-GPU and split configurations. Adds TensorRT-LLM development requirements installation step before test list check.
SLURM Initialization Refactoring
jenkins/scripts/slurm_run.sh
Centralizes Git safe.directory configuration from the SLURM_LOCALID==0 branch into the SLURM_PROCID==0 branch. Removes redundant git config call while preserving job ID save functionality and overall control flow.
Dependency Installation Simplification
scripts/check_test_list.py
Removes the --retries 1 flag from pip install command in the install_python_dependencies function.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • SLURM git config consolidation: Verify that centralizing Git configuration from SLURM_LOCALID==0 to SLURM_PROCID==0 doesn't omit execution paths and maintains intended behavior across process ranks.
  • Test matrix expansion: Confirm GPU variant entries (1 and 2 GPU configurations) are correctly named and aligned with intended test coverage.

scripts/check_test_list.py (1)

25-28: Consider avoiding shell=True for the pip3 install to satisfy S602

This call is safe in practice (since llm_src comes from the local path), but you can eliminate the Ruff S602 warning and avoid shell quirks by calling pip3 without a shell and using cwd:

-def install_python_dependencies(llm_src):
-    subprocess.run(f"cd {llm_src} && pip3 install -r requirements-dev.txt",
-                   shell=True,
-                   check=True)
+def install_python_dependencies(llm_src):
+    subprocess.run(
+        ["pip3", "install", "-r", "requirements-dev.txt"],
+        cwd=llm_src,
+        check=True,
+    )

This keeps behavior the same while tightening the subprocess usage.

jenkins/L0_Test.groovy (1)

1636-1644: Dev requirements are now installed both here and inside check_test_list.py

launchTestListCheck runs pip3 install -r ${llmSrc}/requirements-dev.txt and then check_test_list.py, which still calls install_python_dependencies() when --l0/--qa/--waive are passed, so requirements-dev.txt gets installed twice in the CI path. That’s safe but adds a bit of overhead; if this stage is the only CI entry point, you could eventually add a flag or env switch to let check_test_list.py skip its own dev‑requirements install when invoked from Jenkins.

**/*.py: The code developed for TensorRT-LLM should conform to Python 3.8+
Indent Python code with 4 spaces; do not use tabs
Always maintain the namespace when importing in Python, even if only one class or function from a module is used (e.g., use from package.subpackage import foo and then foo.SomeClass() instead of from package.subpackage.foo import SomeClass)
Python filenames should use snake_case (e.g., some_file.py)
Python class names should use PascalCase (e.g., class SomeClass)
Python function and method names should use snake_case (e.g., def my_awesome_function():)
Python local variable names should use snake_case, with prefix k for variable names that start with a number (e.g., k_99th_percentile = ...)
Python global variables should use upper snake_case with prefix G (e.g., G_MY_GLOBAL = ...)
Python constants should use upper snake_case (e.g., MY_CONSTANT = ...)
Avoid shadowing variables declared in an outer scope in Python
Initialize all externally visible members of a Python class in the constructor
For Python interfaces that may be used outside a file, prefer docstrings over comments
Python comments should be reserved for code within a function, or interfaces that are local to a file
Use Google style docstrings for Python classes and functions, which can be parsed by Sphinx
Python attributes and variables can be documented inline with type and description (e.g., self.x = 5 followed by """<type>: Description of 'x'""" )
Avoid using reflection in Python when functionality can be easily achieved without reflection
When using try-except blocks in Python, limit the except clause to the smallest set of specific errors possible instead of catching all exceptions
When using try-except blocks in Python to handle multiple possible variable types (duck-typing), keep the body of the try as small as possible and use the else block to implement the logic

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 the TensorRT-LLM test infrastructure, the team prefers simple, direct solutions (like hard-coding directory traversal counts) over more complex but robust approaches when dealing with stable directory structures. They accept the maintenance cost of updating tests if the layout changes.

Timestamp: 2025-08-06T13:58:07.506Z
Learning: In TensorRT-LLM, test files (files under tests/ directories) do not require NVIDIA copyright headers, unlike production source code files. Test files typically start directly with imports, docstrings, or code.

Timestamp: 2025-09-17T02:48:52.732Z
Learning: In TensorRT-LLM, `tests/integration/test_lists/waives.txt` is specifically for waiving/skipping tests, while other test list files like those in `test-db/` and `qa/` directories are for different test execution contexts (pre-merge, post-merge, QA tests). The same test appearing in both waives.txt and execution list files is intentional - the test is part of test suites but will be skipped due to the waiver.

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.

32-40: Centralizing job ID write and git safe.directory on SLURM_PROCID==0 looks correct

This block cleanly ensures only rank‑0 saves slurm_job_id.txt and adds safe.directory "*", and the guard avoids duplicate git config entries. The Shellcheck SC2154 warning on jobWorkspace can be ignored here since it’s exported by the sbatch launcher script before slurm_run.sh runs.

2939-2945: New GB200 1/2‑split SBSA configs look consistent

The added "GB200-4_GPUs-PyTorch-1" / "GB200-4_GPUs-PyTorch-2" entries correctly target gb200-x4-oci with l0_gb200_multi_gpus, use 4 GPUs, and align with existing stage naming (so they’ll be picked up by the multi‑GPU filtering logic). No issues from the Jenkins/Groovy side.
