Abstract

Executive Summary on Dagstuhl Seminar 09481 about Synchronous Languages

A. Benveniste, S.A. Edwards, E. Lee, K. Schneider, and R. von Hanxleden

Synchronous languages have been designed to allow the unambiguous description of reactive, embedded real-time systems. The common foundation for these languages is the synchrony hypothesis, which treats computations as being logically instantaneous. This abstraction enables functionality and real-time characteristics to be treated separately, facilitating the design of complex embedded systems. Digital hardware has long been designed using the synchronous paradigm; our synchronous languages were devised largely independently and have placed the technique on a much firmer mathematical foundation.

Feedback from the user base and the continuously growing complexity of applications still pose new challenges, such as the sound integration of synchronous and asynchronous, event- and time-triggered, or discrete and continuous systems.

This seminar aims to address these challenges, building on a strong and active community and expanding its scope into relevant related fields. This year’s workshop includes researchers in model-based design, embedded real-time systems, mixed system modeling, models of computation, and distributed systems.

The seminar was successful in bringing together researchers and practitioners of synchronous programming, and furthermore in reaching out to relevant related areas. With a record participation in this year’s SYNCHRON workshop of more than 50 participants and a broad range of topics discussed, the aims seem to have been well-met. The program of the seminar was composed of around 36 presentations, all of which included extensive technical discussions. The fields covered included synchronous semantics, modeling languages, verification, heterogeneous and distributed systems, hardware/software integration, reactive processing, timing analyses, application experience reports, and industrial requirements. The discussion identified and collected specific needs for future topics, in particular the integration of different models of computation.

The SYNCHRON workshop constitutes the only yearly meeting place for the researchers in this exciting field. The workshops on Synchronous Languages started in 1993 at Schloss Dagstuhl. Since then, the workshop has evolved significantly in its sixteen years of existence. One obvious change is the citizenship of its attendees, which has shifted from being largely French to being truly world-wide. But the biggest change is in its scope, which has grown to expand many languages and techniques that are not classically synchronous but have been substantially influenced by the synchronous languages’ attention to timing, mathematical rigor, and parallelism. Also, while many of the most senior synchronous language researchers are still active, many younger researchers have also entered the fray and taken the field in new directions. We look forward to seeing where they take us next.
