US Patent 7784035 Method for the static analysis of concurrent multi-threaded software

A method for the static analysis of concurrent multi-threaded software which bypasses the state explosion situation that plagues the prior art, thereby making our method scalable while—at the same time—producing no loss in precision. Our inventive method maintains patterns of lock acquisition and lock release by individual threads by constructing augmented versions of the threads. Once the augmented versions have been constructed, our inventive method verifies the concurrent program using existing tools for the verification of sequential programs—thereby greatly reducing implementation overhead. Finally, our inventive augmentation and method is carried out in an automatic manner—without requiring user intervention.
