We present a symbolic approach for checking consistency of OpenMP parallel programs. A parallel program is consistent if it yields the same result as its sequential version despite the execution order among threads. We find race conditions of an OpenMP parallel program, construct the formal model of its raced segments under relaxed memory models, and perform guided symbolic simulation to search consistency violations. The simulation terminates when (1) a witness has been found (the program is… CONTINUE READING
