Abstract

We consider the problem of checking safety properties for concurrent programs. We assume that programs may have (potentially recursive) procedure calls as well as (unbounded) dynamic creation of parallel threads. Each procedure can have a finite number of local variables, and there is a finite number of global variables that can be accessed by all parallel threads. We assume that these variables range over a finite data domain (e.g., booleans).
