Abstract

The major bottleneck of explicit model-checking tools is the limited amount of available memory. Distributed model-checking is an approach to tackle the combinatorial explosion problem. It consists in taking advantage of the aggregate of memory provided by a network of workstations to increase the amount of memory available for model-checking. HELENA is the model-checker of the Quasar tool suite for concurrent software verification. It is a high-level colored Petri net explicit sequential model-checker that implements several state-space reduction and efficient state representation mechanisms. HELENA is currently able to verify safety properties. In this paper we present Cyclades, a distributed version of HELENA, that remains compatible with these reduction techniques. Several distribution mechanisms and some preliminary results are also provided.
