+AlloyStack is a library OS designed for serverless workflow applications. **Portions of the library code are derived from [RuxOS](https://github.com/syswonder/ruxos/tree/main).** It reduces cold start latency through on-demand loading and optimizes intermediate data transfer overhead via reference passing. We provide user-friendly tools and scripts in the AlloyStack code repository to automate the
 build and testing processes. This document guides users in reproducing the experimental results.
