Optimal Stateless Model Checking of Transactional Programs under Causal Consistency

We present a framework for efficient stateless model checking (SMC) of concurrent programs under five prominent models of causal consistency, CCv,CM,CC, Read Committed and Read Atomic. Our approach is based on exploring traces under the program order (po) and the reads from (rf) relations. Our SMC algorithm is provably optimal in the sense that it explores each po and rf relation exactly once. We have implemented our framework in a tool called TRANCHECKER. Experiments show that TRANCHECKER performs well in detecting anamolies in classical distributed databases benchmarks.
