Abstract

Multicore technology has moved concurrent programming to the forefront of computer science In this paper, we look at the problem of reasoning about concurrent systems with infinite data domains and non-deterministic input, and develop a method for verification and falsification of safety properties of such systems Novel characteristics of this method are (a) constructing under-approximating models via symbolic execution with abstract matching and (b) proving safety using under-approximating models.
