May 2026 monthly summary focusing on key accomplishments, business value and technical achievements across repositories. Highlights by repository: - AlexanderDokuchaev/nncf - Key feature delivered: CI Runner Upgrade for Performance. Upgraded the GPU runner type in GitHub Actions workflows from aks-linux-4-cores-28gb-gpu-tesla-t4 to aks-linux-6-cores-55gb-gpu-a10 to leverage newer hardware and support sm_85. This aligns CI with current GPU capabilities, reducing build/test wall time and increasing throughput. Related ticket: CVS-184285. Commit: f37b78eaaacb92369546418e7c49ef588babd629. - aobolensk/openvino - Major bug fixed: iGPU Tests CI Stability via Azure APT Mirrors. Fixed unstable igpu tests by aligning Ubuntu APT sources with Azure mirrors to improve CI stability. Commit: 09815c7bfcedee45a01de1f762e8089caf4c12fe. - Feature delivered: iGPU Tests CI: Custom Docker Image and Ubuntu 22.04 workflow. Introduced a dedicated Docker image for iGPU tests (Ubuntu 22.04) and updated workflows to use it, improving speed and stability of tests. Commit: 5ff2fbd10b676cabfb9863d09d50c14f2082b4fb. Overall impact and accomplishments: - Improved CI performance and reliability across two critical repos, enabling faster feedback cycles, more deterministic tests, and reduced debugging time for developers. - Standardized test environments (Azure mirror-based APT sources and custom Docker image) to minimize variability and flakiness in CI runs. - Demonstrated end-to-end CI optimization: workflow updates, containerization, and environment tuning, delivering measurable gains in test throughput and stability. Technologies/skills demonstrated: - GitHub Actions workflow optimization, GPU runner provisioning, and cross-repo CI strategy - Docker image creation/use and ACR-based pipelines - Ubuntu 22.04 workflow alignment and APT mirror configuration - Cloud/infra coordination (Azure mirrors) and CI stability engineering
