We describe a programming model called PTIDES (Programming Temporally Integrated Distributed Embedded Systems), that extends the discrete-event model of computation with a carefully chosen relationship between real time and model time. PTIDES provides a framework for exploring a family of execution strategies for distributed embedded systems. Our objective in this paper is to present an execution strategy that 1) allows independent events to be processed out of time stamp order, 2) uses clock synchronization as a replacement for null message communication across distributed platforms, 3) defines a notion of when events are safe to process and 4) presents an implementation of a PTIDES model. This work puts forward an execution strategy that is aggressive in concurrent execution of events.
