We present a tool for cluster-based LTL model-checking and reachability analysis. The tool incorporates several novel distributedmemory algorithms and provides a unique interface to use them. We describe the basic structure of the tool, discuss the main architecture decisions made, and briefly explain how the tool can be used.

We present a new release of the parallel and distributed LTL model checker DiVinE. The major improvement in this new release is an extension of the class of systems that may be verified with the model checker, while preserving the unique DiVinE feature, namely parallel and distributed-memory processing. Version 3.0 comes with support for direct model checking of (closed) multithreaded C/C++ programs, full untimed-LTL model checking of timed automata, and a general-purpose framework for interfacing with arbitrary system modelling tools.

Abstract. Recent development in computer hardware has brought more wide-spread emergence of shared-memory, multi-core systems. These architectures offer opportunities to speed up various tasks -among others LTL model checking. In the paper we show a design for a parallel sharedmemory LTL model checker, that is based on a distributed-memory algorithm. To achieve good scalability, we have devised and experimentally evaluated several implementation techniques, which we present in the paper.
