Chores
- Improved CI/CD reliability by increasing retry attempts and extending randomized backoff for network-dependent build steps, reducing transient failures during image fetches and related operations.
- Applied across dependent and main build stages and final commands to stabilize pipelines.
- Users benefit from more predictable release cadence and fewer build-related delays.

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: DoesNOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx"(OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: DoesNOT 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: DoesNOT 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: DoesNOT update GitHub pipeline status.

--only-multi-gpu-test(OPTIONAL) : Only run the multi-GPU tests. Note: DoesNOT update GitHub check status.

--disable-multi-gpu-test(OPTIONAL) : Disable the multi-GPU tests. Note: DoesNOT 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 thestage-list parameter to access the appropriate container environment. Note: DoesNOT update GitHub check status.

📝 Walkthrough

Walkthrough

The Jenkins pipeline file jenkins/BuildDockerImage.groovy increases llmExecStepWithRetry numRetries to 6 at four call sites and widens randomSleep for docker pull-related steps to a 600–1199 second window. No other parameters or public signatures changed.

Changes

Cohort / File(s)	Summary of Changes
Jenkins pipeline retry/backoff adjustments `jenkins/BuildDockerImage.groovy`	- Increased llmExecStepWithRetry`numRetries` from 3 to 6 across dependent build, main build, final command, and NSPECT steps - Expanded randomSleep used around docker pull-related steps from 300–599s to 600–1199s - No changes to`shortCommondRunTimeMax` or exported interfaces

298-308:Retries + longer jitter: good; switch to ThreadLocalRandom and make bounds explicit

The change improves resilience. Minor refactor to avoid double/float truncation and to make the bounds explicit.

Apply this diff:

-                def randomSleep = (Math.random() * 600 + 600).toInteger()+                def randomSleepMin = 600+                def randomSleepMax = 1200  // exclusive+                def randomSleep = java.util.concurrent.ThreadLocalRandom.current().nextInt(randomSleepMin, randomSleepMax)-                trtllm_utils.llmExecStepWithRetry(this, script: "docker pull ${TRITON_IMAGE}:${TRITON_BASE_TAG}", sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)+                trtllm_utils.llmExecStepWithRetry(this, script: "docker pull ${TRITON_IMAGE}:${TRITON_BASE_TAG}", sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)@@-                """, sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)+                """, sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)

Also consider exponential backoff with jitter in llmExecStepWithRetry to avoid worst-case 20 min waits per attempt across many parallel jobs.

327-337:Duplicate jitter logic: DRY and consistent bounds

Mirror the ThreadLocalRandom refactor here to keep behavior consistent and readable.

Apply this diff:

-            def randomSleep = (Math.random() * 600 + 600).toInteger()+            def randomSleepMin = 600+            def randomSleepMax = 1200  // exclusive+            def randomSleep = java.util.concurrent.ThreadLocalRandom.current().nextInt(randomSleepMin, randomSleepMax)-            trtllm_utils.llmExecStepWithRetry(this, script: "docker pull ${TRITON_IMAGE}:${TRITON_BASE_TAG}", sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)+            trtllm_utils.llmExecStepWithRetry(this, script: "docker pull ${TRITON_IMAGE}:${TRITON_BASE_TAG}", sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)@@-            """, sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)+            """, sleepInSecs: randomSleep, numRetries: 6, shortCommondRunTimeMax: 7200)

689-689:NSPECT step: add jittered sleep to avoid hot-loop retries

The other steps use jitter; mirror it here to reduce thundering herd on failures.

Apply this diff:

-                            trtllm_utils.llmExecStepWithRetry(this, script: cmd, numRetries: 6, shortCommondRunTimeMax: 7200)+                            def nspectSleep = java.util.concurrent.ThreadLocalRandom.current().nextInt(60, 180)+                            trtllm_utils.llmExecStepWithRetry(this, script: cmd, sleepInSecs: nspectSleep, numRetries: 6, shortCommondRunTimeMax: 7200)

jenkins/BuildDockerImage.groovy (1)
298-299:Guard against excessive total wait vs pipeline timeout
With 6 retries and 600–1199s sleeps, worst-case per step adds ~100 minutes of delay (excluding work time). Across multiple stages in parallel, this can push the 24h pipeline timeout.
Please confirm recent runs won’t hit the global 24h timeout; if close, consider:
lowering sleep window or retries on non-critical pulls,
using exponential backoff with max cap,
exposing retries/sleep bounds as Jenkins parameters for quick tuning.
