+ An Open-Source Coordination Language for Deterministic Integration + of Cyber-Physical Systems +
++ Half-day hands-on tutorial (~4 hours) +
++ This half-day, hands-on, interactive tutorial introduces{" "} + Lingua Franca (LF), an open-source + coordination language designed for building deterministic, + concurrent, and time-sensitive cyber-physical systems. + Participants will explore LF's core concepts through a technical + overview, CPS-focused demonstrations, and hands-on programming + sessions using C and Python as well as the LF coordination + language. +
++ This tutorial emphasizes how LF enables deterministic + concurrency, simplifies integration, and enhances reliability + across CPS and IoT domains. The tutorial is intended for + researchers, engineers, and graduate students with programming + experience interested in robust CPS design. +
+ ++ CPS-IoT Week participants including academic researchers, + industry engineers, and graduate students working on CPS/IoT. + No prior experience with LF is requiredβbasic proficiency in C + and/or Python is recommended. +
++ Cyber-physical systems (CPS) and IoT applications often involve + multiple concurrent components interacting under real-time + constraints. Ensuring deterministic behavior and coordinated + timing across these components is a notorious challenge with + conventional programming approaches (threads, pub/sub, actor + frameworks, etc.). +
++ Lingua Franca is a polyglot coordination language designed to + address this challenge by offering a framework for building + concurrent, time-sensitive systems that behave deterministically + and predictably. An LF program defines interactions between + reactive components called reactors and emphasizes + deterministic coordination with explicit handling of timing. +
++ By using LF, CPS developers can coordinate sensing, computation, + and actuation across devices with guarantees of logical timing + order and thread-safe determinism that are difficult to achieve + with traditional methods. +

+
- + Deterministic Concurrency: Race-free + execution on multiple cores or devices without special + synchronization code + +
- + Explicit Timing Semantics: Specify and + maintain precise temporal behavior without ad-hoc timing + code + +
- + Polyglot Support: Reactor logic can be + written in C, Python, C++, Rust, or TypeScript + +
- + Distributed Execution: Built-in support + for federated execution across networked devices + +
+ Total duration: ~4 hours (half-day tutorial including breaks) +
