Abstract

This paper introduces an algorithm for parallel simulation capable of executing the critical path without a priori knowledge of the model being executed. This algorithm is founded on the observation that each initial event in a model causes a stream of events to be generated for execution. By focusing on the parallelization of event streams, rather than logical processes, we have created a new simulation engine optimized for large scale models (i.e., models with 1 million LPs or more).
