Abstract

Parallel or Distributed Discrete Event Simulation (PDES) refers to the concurrent execution of a single discrete event simulation application on a parallel or distributed computing system. Most available PDES implementations provide user level library support for writing distributed simulation applications. We discuss how OS support can be designed to facilitate optimistic PDES of large, complex simulation models. TWLinuX is our implementation of these concepts through modification of Linux. Through TWLinuX, a simple, low cost network of machines becomes a high performance discrete event simulation platform.
