Shaokai worked on core scheduling and code generation features for the lf-lang/lingua-franca and lf-lang/reactor-c repositories, focusing on distributed and real-time systems. He simplified scheduler selection logic by removing deadline-based policies, making event handling more predictable and maintainable. Using C and Java, he enhanced federated code generation to prevent infinite loops and stack overflows, introducing recursive delay calculations and robust test coverage. Shaokai also improved event scheduling semantics and type safety in reactor-c, refining policy handling for same-tag events. His work emphasized code refactoring, concurrency management, and testing, resulting in cleaner, more reliable infrastructure for embedded and distributed workflows.

January 2025 monthly summary for lf-lang/lingua-franca. Delivered robust federated code-generation improvements and strengthened test coverage to improve reliability in distributed workflows. Key outcomes include cycle-free min-delay calculation, backward tracing of physical actions, and safeguards against stack overflows during compile-time evaluation.

November 2024: Delivered Scheduler Selection Simplification in lf-lang/lingua-franca by removing the deadline-based GEDF_NP logic, resulting in a simpler and more predictable scheduler decision path. Eliminated pickScheduler() and its helper hasDeadlines() in CGenerator.java to reduce dead code and maintenance burden, enabling easier future policy experimentation. Core commit: 9bd8dacdba9de15f22dd784e4b9077f01c2625f2. This work improves scheduling determinism, reduces risk of deadline-driven edge cases, and accelerates future enhancements.
