Abstract
Systems and methods are disclosed to check properties of bounded concurrent programs by encoding concurrent control flow graph (CFG) and property for programming threads as a first-order formula F; initializing an interference abstraction (IA); encoding the IA as a first-order formula F; checking a conjunction of Fand F(F^F); if the conjunction is satisfiable, checking if an interference relation (IR) is spurious, and iteratively refining the IA; and if the conjunction is unsatisfiable, checking if an interference relation (IR) is spurious, and iteratively refining the IA.
