Distributed local resolution of Boolean equation systems

Boolean equation systems (BESs) allow to represent various problems encountered in the area of propositional logic programming and verification of concurrent systems. Several sequential algorithms for global and local BES resolution have been proposed so far, mainly in the field of verification; however, these algorithms do not scale up satisfactorily as the size of BESs increases. In this paper, we propose a distributed algorithm, called DSOLVE, which performs the local resolution of a BES using a set of machines connected by a network. Our experiments for solving large BESs using clusters of PCs show linear speedups and a scalable behaviour of DSOLVE w.r.t. its sequential counterpart.
