[Seminar] Localizing and Explaining Non-deadlock Concurrency Bugs

Concurrency bugs are difficult to debug because of nondeterministic behaviors of concurrent programs. Existing fault-localization techniques for non-deadlock concurrency bugs do not provide the comprehensive information to identify and understand the bugs. In this talk, I will present a technique, called Griffin, that assists developers in debugging non-deadlock concurrency bugs, from finding the locations of concurrency bugs to explaining the bugs. The empirical studies show that the technique locates concurrency bugs at the top rank for our C++/Java subjects, and the technique clusters failing executions and memory-access patterns for the same bug with few false positives.
