Study for Parallel Scheduling of HLA-Based Simulation Objects

Abstract

HLA has become the mainstream of distributed simulation technology, but serial execution of simulation objects in the existing HLA run-time infrastructure results in huge computation and communication bottlenecks. It has been becoming a focus of attention to accomplish the parallel scheduling of HLA simulation application. This paper proposed a method for parallel scheduling of HLA-based simulation objects. We introduced the base classes named SimObject and Interaction to map object attributes and interaction parameters from FOM files to object instances and interaction instances, and constructed additional three new service components: simulation manager, object manager, interaction manager. This way, simulation objects in a federate or across different federates can be scheduled in parallel, improving the running efficiency of simulation system.
