An Implementation of the SSF Scalable Simulation Framework on the Cray MTA

摘要

Large-scale parallel discrete event simulations of massivenetworks, such as the Internet, are "Grand Challenge"problems: packet level simulation of even a small fraction ofthe Internet would consume the resources of the most powerfulcomputers available. We reimplement the SSF ScalableSimulation Framework so we can run large-scale networksimulations originally written for DaSSF. Our implementation,CraySSF, is designed for the Cray-MTA, a multithreadedsupercomputer architecture developed specificallyto address large-scale computations of the kind that arenot easily distributed. This paper describes the architecture,implementation issues, and preliminary performanceresults on a variety of (stock) serial and parallel architectures.
