Abstract

In [J. Barnat, L. Brim, and J. Chaloupka. Parallel Breadth-First Search LTL Model-Checking. In 18th IEEE International Conference on Automated Software Engineering (ASE'03), pages 106-115. IEEE Computer Society, Oct. 2003.] we proposed a parallel graph algorithm for detecting cycles in very large directed graphs distributed over a network of workstations. The algorithm employs back-level edges as computed by the breadth first search. In this paper we describe how to turn the algorithm into an explicit state distributed memory LTL model checker by extending it with detection of accepting cycles, counterexample generation and partial order reduction. We discuss these extensions and show experimental results.
