Répartition de programmes synchrones temps réel

Abstract : Synchronous programming allows an easy description of reactif systems which must react continuously to their physical environment. Such systems are often distributed ones for some reasons like physical implementation or fault tolerance. Besides, these systems are also real time critical systems. We aim to study some implementation methodologies for such systems on networks of calculators. We show how synchronous programming is not robust for these systems because logical time is different from real time. We analyse robustness problems for continuous and discrete systems. We particularly provide some tools for simulating quasi-synchronous distributed architectures and for checking robustness. We also propose a synchronization protocol for non robust systems. Finally, we present a fault tolerance approach for quasi- synchronous distributed systems.
