Delivered scalable testing workflows, improved observability, and labeling corrections to support faster release readiness. Key business value includes faster feedback loops, reduced flaky tests, and more predictable releases across CI and CH hardware test infra. Technologies demonstrated include Git, GitHub Actions, CI/CD pipelines, BH hardware test infrastructure, and machine-learning model testing (ttnn, Frequent model) with APC/regression fixes. Key features delivered and major improvements: - CIv2 model jobs for Frequent model and ttnn tests deployed (PR #26395) - BH nightly run scaling: added support for 2x/4x/8xP150 to validate performance under varied loads (PR #26535) - Added ensure-bh-links-online GitHub Action to verify BH multicard Ethernet links before tests (PR #26961, related updates #26972) - Deskbox health check improvement: set minimum connections to 4 for system health checks (#26697) - Watcher feature enabled to improve observability and resilience (commit: 80ee29fed090133bbf2630b487f3f827467dbb27) Major bugs fixed: - Reverted truncating fp32->bf16 rounding rule to restore expected numerical behavior (commit 715d6fc6a0fd1df9174f0b48af5a2acf196c3492, 1cb9bf36840bdd097ad1c95504df819a3607c908) - Update TG llama prefill_pcc to fix APC (#26155) (commits aa3e72b7c7659a2a9706f65d7c0a60907c9f02db, b1e6085de1f4f60107111c3d99d6a0833f7eea15) - Fix decode_pcc for APC (#26169) (commits 03f342bba65740c53fa8c6b91868be964eeba692, e92dd76025f9e5dd439d6145f3c2cbebf4cde657) - Skip test_sampling on BH (#26177) (commits 3f728d717430d3ea773cc4054e4a7222ba8682f0, 10d5c0c4276958e4bb582829d0d33cd222205d7a) - Add missing in-service label (#26410) (commits 582f7f415068dc868334dfaeb0f7cd3bf4314556, fb6c03f0a3e9ab681466e469ee3ca9d7cc2cbf65) - Handle non-beta tt-ubuntu civ2 runners (#26461) (commits 8880382e51c7819c44bd263bd6a5c361c4ec0d85, 18d836a21b3e155994dc22bbc9b8ad2d0c5d4561) - Fix/exclude skipped workflow runs from produce data pipeline (#26469) (commits f5dcd63164a501b02c8453b56aadd610b8a1b7de, 7da105870ead5a936718cc277ed9c86f8bdd2293) - Demo/WH tests: skip or adjust flaky tests (e.g., #27195, #27313, #27380, #27456) Overall impact and accomplishments: - Improved release readiness through more reliable CI and hardware test coverage, reducing time wasted on flaky tests. - Strengthened data pipeline accuracy and test selection by excluding skipped runs and prioritizing failures when reading annotations. - Enhanced observability and reliability with watcher, health checks, and links verification, enabling faster diagnosis and remediation.

Jul 1, 2025July 2025 monthly summary for tenstorrent/tt-metal focused on expanding test coverage, stabilizing CI workflows, and extending hardware/test configurations. Delivered ETH-focused unit tests for BH LLMBox upstream tests, refined the upstream BH LLMBox test workflow to run system health checks first, and created a BH LLMBox demo wrapper. Improved deployment visibility with a gh-pages CI/CD update and enhanced workflow labeling. Expanded hardware coverage with a split demo test approach (P100 and P150) and migrated to CIv2 runners (P150b) to accelerate testing. Consolidated CI stability with environment handling (LLAMA_DIR), civ2 compatibility improvements, lint fixes, and test-name hygiene. Reverted several stability-risk changes to reduce flakiness (e.g., big-buffers/ttnn changes, gather moves, and TX-queue tweaks) to ensure reliable CI feedback. Overall, these changes yield faster, more reliable feedback loops, broader hardware coverage, and stronger upstream BH LLMBox validation, delivering clear business value through increased quality and deployment velocity.

Jun 1, 2025June 2025 performance highlights for tenstorrent/tt-metal focused on stabilizing the data and test pipelines, expanding coverage, and delivering automation foundations for BH QB workflows. Key outcomes include the initialization of the BH QB pipeline with associated tests and ttnn stress testing to accelerate nightly validation, the renaming and wrapping of llmbox tests for consistency, and the introduction of Merge Gate and CYO controls to production data YAML for safer data workflows. Concurrently, several risky changes were reverted to restore stability (auto sharding in pool2d with L1 memory usage check, BH block_ct_dim != full_ct_dim fix, split halo padding across BR/NC cores, Yolov4 trace support, and TT BOT docs token usage in produce_data), and a dataset pin was applied to stabilize dependencies. Superset timestamp fixes for skipped jobs were also completed. Overall, these efforts improved CI reliability, data-production safety, and test coverage, positioning the project for more predictable releases and performance optimization.

Apr 1, 2025April 2025: Delivered reliability and CI/CD enhancements for tenstorrent/tt-metal, strengthening data pipeline observability, artifact handling, and deployment visibility. Key features delivered include distinguishing timeouts from hangs in the Superset data pipeline, making the MLPerf mount read-only by default in workflows, removing legacy mount-related steps (checkout-with-submodule-LFS), setting default paths for UUID artifact uploads, and deploying tt-metal results to gh-pages for easy sharing. Build and test pipeline improvements include integrating UMD unit tests into the build-artifact step and updating artifact paths. Major bug fixes addressed issues in post-commit workflows and test infrastructure, such as reverting vector mode exposure for the sigmoid op, increasing BH post-commit test timeout, ensuring gtest annotation scripts run with a working directory, allowing better error handling in produce_data, and fixing microbenchmarks artifact upload path. Overall impact: more reliable pipelines, faster feedback loops, clearer test reporting, and improved artifact management. Technologies/skills demonstrated: GitHub Actions, containerized CI for post-commit workflows, workflow simplifications, artifact management, and test infrastructure modernization.
