  abstract= "In traditional real-time multiprocessor schedulability
     analysis it is required that all tasks are entirely serial.
     This implies that if a task is written in a parallel
     language such as occam, all parallelism in the task must be
     suppressed to enable schedulability analysis. Part of the
     reason for this restriction is the difficulty in analysing
     execution times of programs with a complex parallel
     structure. In this paper we introduce an abstract model for
     reasoning about the temporal properties of such programs.
     Within this model, we define what it means for a process to
     be easier to schedule than another, and the notion of
     upper bounds on execution times. Counterintuitive temporal
     behaviour is demonstrated to be inherent in all systems
     where processes are allowed an arbitrary parallel structure.
     For example, there exist processes that are guaranteed to
     complete on some schedule, that may not complete
     if executing less than the expected amount of computation.
     Not all processes exhibit such counterintuitive behaviour,
     and we identify a subset of processes that are well-behaved
     in this respect. The results from this paper is a necessary
     prerequisite for a complete schedulability analysis of
     systems with an arbitrary parallel structure."
