Jul 1, 2026July 2026 (ROCm/aiter) – This month concentrated on strengthening CI reliability, optimizing resource usage, and expanding automated smoke testing to accelerate feedback and reduce PR blockers. Key CI improvements included moving SGLang accuracy tests to nightly runs to prevent PR blocking, reverting non-blocking test log uploads to restore blocking, and implementing automated smoke testing for ATOM DI and vLLM on Spur with Slurm and result parsing. In addition, hardware- and pool-level optimizations were completed by removing the MI300X 8-GPU runner, upgrading and reallocating to 8-GPU configurations, and migrating ATOM 4GPU CI jobs to the do-mi350x-4 pool to improve throughput. A vLLM disaggregated smoke workflow was added for Spur, with staged logs, model configuration adjustments, and targeted node pinning, enhancing observability. Overall, these efforts delivered more reliable builds, faster feedback, and better scalability of the CI/CD pipeline while expanding end-to-end smoke coverage.

Apr 1, 2026April 2026 (ROCm/aiter): Delivered major CI/CD enhancements and test-automation improvements that boost validation speed, reliability, and observability across MI35X/MI300X fleets. Focus areas included AMD CI monitoring, artifact/signal management, test execution stability, and targeted workflows, enabling faster feedback to developers and reduced CI downtime. Key features delivered: - AMD CI Monitoring Enhancements: reusable AMD CI job monitor with per-job status, runner fleet metrics, PR-triggered validation, and GitHub Step Summary integration. - CI Artifact and Signal Management Improvements: scoped signal artifact downloads and publication of latest wheel manifests to downstream checks. - CI Test Execution Reliability and Performance: runner label analytics, snapshot-based PR monitor execution, concurrency tuning, extended clang toolchain timeout, and reuse of prebuilt CK checkout. - Standalone OPUS Test Workflow: dedicated standalone OPUS test workflow for independent MI35X/MI325 validation. - MI35X Deepseek ATOM Tests Enablement: enabled MI35X ATOM tests with /models cache routing and mounted paths for faster runs. Major bugs fixed: - Reverted Ruff pre-checks to baseline to address regressions. - Fixed rope THD backward test collection by removing stale in-place parametrization. - Fixed pre-check signal artifact lookup for PR reruns. - Fixed prebuild image related issues. Overall impact and accomplishments: These changes reduce CI time, lower API usage and rate-limits, improve test reliability, and provide clearer visibility into runner capacity and queue times. They enable more scalable validation and faster delivery of software updates. Technologies/skills demonstrated: - GitHub Actions, Python scripting, PyYAML, Black formatting, Ruff/ReviewDog integration, Docker login resilience, artifact management, and CI performance tuning.
