Abstract
A system and method for dynamic data race detection for concurrent systems includes computing lockset information using a processor for different components of a concurrent system. A controlled execution of the system is performed where the controlled execution explores different interleavings of the concurrent components. The lockset information is used during the controlled execution to check whether a search subspace associated with a state in the execution is free of data races. A race-free search subspace is dynamically pruned to reduce resource usage.
