Abstract

This paper presents the issues involved in the design and development of ussf. Parallel simulation techniques are used to enable optimal time versus resource tradeos in ussf. The techniques employed in the framework to reduce and regulate the memory requirements of the simulations are described. The API needed for model development is illustrated. The results obtained from the experiments conducted using various system models with two parallel simulation kernels (comparing a conventional approach with ussf) are also presented. Key Words: Large Scale Modeling, Parallel and Distributed Simulation, Time Warp Simulation, Unsynchronized Simulation 1 Support for this work was provided in part by the Defense Advanced Research Projects Agency under contract DABT63-96{C{0055. 1 2 RAO AND WILSEY 1.
