Abstract: A computer implemented method for the verification of concurrent software programs wherein the concurrent software program is partitioned into subsets named concurrent trace programs (CTPs) and each of the CTPs is evaluated using a satisfiability-based (SAT) symbolic analysis. By applying the SAT analysis to individual CTPs in isolation the symbolic analysis is advantageously more scalable and efficient.

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.
