During June 2025, Baiyun Yu focused on modernizing and hardening continuous integration environments for the ofiwg/libfabric and aws/aws-ofi-nccl repositories. Baiyun upgraded CI pipelines to Ubuntu 22.04, ensuring compatibility with current OS toolchains and improving reliability of pull request validation. The work involved updating Jenkins-based workflows and Groovy scripts to support the new environment, while maintaining stability across EFA, SHM, and TCP test stages. By aligning CI infrastructure with supported operating systems, Baiyun reduced maintenance overhead and enabled faster developer feedback. The changes demonstrated careful cross-repository coordination and a pragmatic approach to DevOps and cloud infrastructure management.
