Parallel Kind

PKIND is a parallel k-induction-based model checking architecture for verifying safety properties of synchronous systems. The architecture, which is strictly message-based, is designed to minimize synchronization delays and easily accommodate the incorporation of incremental invariant generators to enhance basic k-induction. A first level of parallelism is introduced in the k-induction procedure itself by executing the base and the inductive steps concurrently. A second level of parallelism allows the addition of one or more independent processes that incrementally generate invariants for the system being verified. The invariants are fed to the k-induction loop as soon as they are produced and used to strengthen the induction hypothesis.
