The use of model-checking for the verification of concurrent algorithms

The design of concurrent algorithms tends to be a long and difficult process. Increasing the number of concurrent entities to realistic numbers makes manual verification of these algorithms almost impossible. Designers normally resort to running these algorithms exhaustively yet can never be guaranteed of their correctness. In this report, we propose the use of a model-checker (SMV) as a machine-automated tool for the verification of these algorithms. We present methods how this tool can be used to encode algorithms and allow properties to be guaranteed for uni-processor machines running a scheduler or SMP machines. We also present a language-generator allowing the designer to use a description language that is then automatically converted to the model-checker’s native language. We show how this approach was successful in encoding a concurrent algorithm and is able to verify the desired properties.peer-reviewe
