PROFILE

Emma Qiao

Qing Qiao engineered robust CI/CD and test automation solutions for the nv-auto-deploy/TensorRT-LLM repository, focusing on stabilizing GPU-accelerated validation pipelines and accelerating release cycles. Leveraging Python, Jenkins, and Docker, Qing refactored test workflows for isolation, introduced dynamic test waivers, and optimized Slurm-based test distribution to reduce wall time and CI noise. He expanded hardware coverage, standardized dependency management, and implemented retry logic for deployment reliability. By upgrading the NVIDIA software stack and maintaining code hygiene, Qing improved build reproducibility and test resilience. His work delivered faster feedback, safer mainline merges, and a more deterministic release process for the team.

Jul 1, 2025

July 2025 monthly summary for nv-auto-deploy/TensorRT-LLM. Key features delivered, major bugs fixed, overall impact, and technologies demonstrated focused on stability, reliability, and reproducible builds to accelerate business value. Key features delivered: - CI Stability and Test Timeouts Improvements: Adjusted test timeouts across configurations; unwaived a fixed test; default timeout set to 1 hour; increased unittest execution window to accommodate long-running tests, reducing flaky failures and test churn. - Dependency Pinning for Triton: Pin the Triton package to version 3.3.1 to ensure reproducible builds and compatibility with the rest of the stack. Major bugs fixed: - Waives Management and Skipping Known Failing Tests: Implemented and maintained waived lists, test decorators, and post-merge CI adjustments to unblock releases; integrated with Slurm waives and explicit skip markers to prevent known issues from blocking mainline and releases. Overall impact and accomplishments: - Significantly improved CI reliability and predictability of release pipelines by reducing flaky test blockers and stabilizing long-running test executions, enabling faster feedback and safer mainline merges. - Achieved a more stable and reproducible build surface through explicit dependency pinning, reducing environment drift and integration risk. Technologies and skills demonstrated: - CI infrastructure tuning, test orchestration, and waiver workflow management; Slurm integration for test waivers; dependency pinning strategies; Python scripting and Git-based change traceability.
