摘要

Multi-threaded programs play an increasingly important role in current multi-core environments. Exposing concurrency bugs and debugging such multi-threaded programs are quite challenging due to their inherent non-determinism. In order to mitigate such non-determinism, many approaches such as record-and-replay have been proposed. However, those approaches often suffer significant performance degrad...
