Global predicates in parallel programs are predicates considering the state of more than one process. They are a useful concept for debugging parallel programs, e.g., for specifying assertions or breakpoints. In this paper 9-predicates are defined and examined, a restricted class of global predicates. 9-predicates are defined by two local predicates which have to be simultaneously satisfied by two different processes.Such predicates are frequently needed to express synchronization properties.

Furthermore, it is outlined how 9-predicates can be used for global breakpoints and where to stop a parallel program reaching such a breakpoint. The underlying machine models is a fixed set of processes communicating by message passing or shared memory.
