Project Abstract:

It is widely believed that the High Level Architecture (HLA) is successful in promoting interoperability and reusability in modeling and simulation. With the increase in complexity of simulations, there is a growing need for accessing large amounts of computing resources and data sets which could be geographically distributed. The Grid provides an infrastructure for collaborative resource sharing and execution of largescale applications among virtual organizations. This paper proposes an interoperability model based on both conceptual and practical merits and extends HLA’s existing practical interoperability to support Grid-wide distributed simulation. More specifically, we propose a distributed simulation framework, called HLAGrid. The framework uses a Federate-Proxy-RTI architecture, which hides the heterogeneity of the simulators, simulators’ execution platforms, and how the simulators communicate with the RTI. The architecture also supports
