Spack's Continuous Integration (CI) system is essential for building and distributing reliable HPC software packages. It has dramatically scaled from building hundreds to hundreds of thousands of packages weekly. Leveraging GitLab, Spack CI has evolved from a Linux-only build system to orchestrating runners across diverse providers, architectures, and platforms, supporting multiple domain stacks like E4S, HEP, and Radiuss. Through enhanced monitoring and data-driven methodologies, including machine learning, Spack CI has gained insights to optimizing resource allocation and analyzing failure modes. Improvements to binary caching reduce storage and prevent race conditions. The core goal is to maintain a resilient and efficient CI ecosystem, ensuring the reliability of Spack's HPC software for its expanding community.
