In this paper we present sequential as well as distributed algorithms for model checking computational tree logic over finite-state systems specified as Petri nets. The algorithms rely on an explicit representation of the system’s state space but do not require the transition relation to be explicitly available; it is recomputed whenever required. This approach allows us to model check very large systems, with hundreds of millions of states, in a fast and efficient way. For the case studies addressed, the distributed algorithms scale very well, as they show efficiencies in the range of 60% to 95%, depending on the test cases and case studies at hand.
