A grid infrastructure for hybrid simulations

摘要

The last decade has witnessed the rapid growth of both the complexity and the scale of problem domains. A variety of techniques have been developed for fostering large and even hybrid simulations over the Internet. Along this direction, existing work normally only suit for coarse-grained models. In this paper, we present a Grid infrastructure which applies to a hybrid simulation comprising models of different grains and/or models of various types in nature. A gateway approach has been proposed to present simulation models of an individual administrative domain for fine-grained problems, and it also bridges simulation models operating in multiple administrative domains to form hybrid simulations for studying large and complicated problems. A prototype infrastructure has realized with the support of federated simulation technology. Potential applications, such as simulation of huge crowd, have also been discussed.
