Parallel simulation of discrete event systems

Abstract

Parallel simulation has not been widely accepted by the simulation practitioners due to the lack of language support and tools necessary for developing eecient parallel simulators. This paper describes the design of SPaDES (Structured Parallel Discrete-Event Simulation), a struc-tured parallel simulation workbench for developing portable simulation models, and a platform for designing experimentation of parallel simulation synchronization protocols. It consists of a C++ based parallel simulation language called SPaDES/C++ that allow the users to focus on modeling the systems to be simulated and not on the details of parallelization, i.e., independent of parallel programming and parallel simulation mechanism. SPaDES is distinguished from other parallel simulation languages because it integrates a process-oriented modeling methodology with object-oriented programming. A comparison of SPaDES/C++ with CSIM and Simscript using an example application is discussed.
