Worked on the microsoft/hcsshim repository to enhance Windows container resource management by implementing CPU affinity and CPU group affinity support for Windows JobObjects. Leveraged Go and the Windows API to wire CPU affinity controls directly into JobObject limits, ensuring precise and enforceable resource boundaries for containers. Developed robust validation logic to guarantee CPU affinity settings comply with Windows constraints, and updated related APIs and tests to align with the Host Compute Service schema and OCI specifications. These changes improved resource isolation, performance predictability, and reliability for multi-tenant Windows container workloads, particularly on Windows Server 2022 and newer environments.
