Abstract : SimGrid MC is a stateless model checker for distributed systems that is part of the SimGrid Simulation Framework. It verifies implementations of distributed algorithms, written in C and using any of several communication APIs provided by the simulator. Because the model checker is fully integrated in the simulator that programmers use to validate their implementations, they gain powerful verification capabilities without having to adapt their code. We describe the architecture of SimGrid MC, and show how it copes with the state space explosion problem. In particular, we argue that a generic Dynamic Partial Order Reductions algorithm is effective for handling the different communication APIs that are provided by SimGrid. As a case study, we verify an implementation of Chord, where SimGrid MC helped us discover an intricate bug in a matter of seconds.
