libDMC: a library to Operate Efficient Distributed Model Checking

Abstract : Model checking is a formal verification technique that allows to automatically prove that a system's behavior is correct. However it is often prohibitively expensive in time and memory complexity, due to the so-called state space explosion problem. We present a generic multithreaded and distributed infrastructure library designed to allow distribution of the model checking procedure over a cluster of machines. This library is generic, and is designed to allow encapsulation of any model checker in order to make it distributed. Performance evaluations are reported and clearly show the advantages of multi-threading to occupy processors while waiting for the network, with linear speedup over the number of processors.
