The conditional-event approach to distributed simulation

摘要

A new conservative approach to distributed simulation that appears to be efficient is proposed. Performance measures of the simulator executing queueing network models are discussed. This work departs from earlier work on distributed simulation in two aspects. The topological structure of simulators described in the literature mirrors the structure of the physical system. By contrast, this method, messages are used for a variety of purposes, and the process interconnection structure of the simulator need not reflect the structure of the physical system. The second difference between the method proposed here and that used in the literature is the use of conditional events, and extension of the concept that forms the basis for sequential simulation. Experimental results on the Intel iPSC/1 running Cosmic C are reported.
