Data races are one of the major causes of concurrency bugs in multithreaded programs, but they are hard to find due to nondeterministic thread scheduling. Data race detectors are essential tools that help long-suffering programmers to locate data races in multithreaded programs. One type of detectors precisely detects data races but is sensitive to thread scheduling, whereas another type is less sensitive to thread scheduling but reports a considerable number of false positives. In this paper, the authors propose a new dynamic data race detector called SimpleLock that accurately detects data races in a scheduling insensitive manner with low execution overhead.
