Verifying MPI Applications with SimGridMC
Workshop: 1st International Workshop on Software Correctness for HPC Applications (Correctness 2017)
Abstract: SimGridMC (also dubbed Mc SimGrid) is a stateful Model Checker for MPI applications. It is integrated to SimGrid, a framework mostly dedicated to predicting the performance of distributed applications. We describe the architecture of McSimGrid, and show how it copes with the state space explosion problem using Dynamic Partial Or- der Reduction and State Equality algorithms. As case studies we show how SimGrid can enforce safety and liveness properties for MPI applications, as well as global invariants over communication patterns.
