"We recommend that capturing, replaying and isolating thread schedules be an integrated part of testing and debugging concurrent applications. Each time a test fails, delta debugging could be used to isolate the failure-inducing schedule difference. Given a capture/replay tool like DEJAVU, the approach presented in this paper is straightforward and easy to implement." (Conclusion)

AbstractConsider a multi-threaded application that occasionally fails due to non-determinism. Using the DEJAVU capture/replay tool, it is possible to record the thread schedule and replay the application in a deterministic way. By systematically narrowing down the difference between a thread schedule that makes the program pass and another schedule that makes the program fail, the Delta Debugging approach can pinpoint the error location automatically - namely, the location(s) where a thread switch causes the program to fail. In a case study, Delta Debugging isolated the failure-inducing schedule difference from 3.8 billion differences in only 50 tests.
