Experiments with distributed Model-Checking of group-based applications

National audienceGroup-based distributed systems are specific cases of distributed applications with a parameterized topology. They are naturally modelled by systems with a very large state space. We encode the behavioural semantics of group-based applications using the intermediate format FIACRE. We have experimented with model-checking of such systems, using the CADP verification toolset, and in particular the distributor tool. This allowed us to generate very large but finite state-space on the PacaGrid cloud infrastructure. We have then been able to compare different techniques for generating state-spaces, and experiment with different sizes of the modelled system and of the experimental platform
