REAL-TIME SCHEDULING OF LOGICAL PROCESSES FOR PARALLEL DISCRETE-EVENT SIMULATION

We tackle the problem of scheduling logical processes that can significantly affect the performance of running parallel simulation either in real time or proportional to real time. In particular, we present a comprehensive solution to dealing with the mixture of simulated and emulated events in a full-fledged conservatively synchronized parallel simulation kernel to improve efficiency and timeliness for processing the emulated events. We propose an event delivery mechanism for the parallel simulator to incorporate emulated events originated from the physical system. We augment the parallel simulation API to support emulation capabilities independent from a particular simulation domain. Preliminary experiments demonstrate the our simulator’s real-time performance on high-performance computing platforms.
