Abstract:We present an efficient data race prediction algorithm that uses lock-reordering based incremental search on time-stamped lock histories for solving multiple races effectively. We balance prediction accuracy, coverage, and performance with a specially designed pairwise reachability algorithm that can store and re-use past search results, thereby, amortizing the cost of reasoning over redundant and overlapping search space. Compared to graph-based search algorithms, our algorithm incurs much smaller overhead du… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
