An Algorithmic Framework for Synthesis of Concurrent Programs

We present a framework that takes unsynchronized sequential processes along with a temporal specification of their global concurrent behaviour, and automatically generates a concurrent program with synchronization code ensuring correct global behaviour. The synthesized synchronization code is based on monitors with wait and notify operations on condition variables, and mutual-exclusion locks. Novel aspects of our framework include realistic low-level synchronization implementations, synthesis of both simple coarse-grained synchronization and more complex fine-grained synchronization, and accommodation of both safety and liveness in global correctness properties. The method is fully automatic as well as sound and complete.
