Design and realization of the simulation component-based parallel framework for HLA Federate

While the difficulty and complexity of simulation system increasing, the development efficiency and execution performance of the large-scale distributed simulation system (LSDSS) must be improved effectively. Furthermore, while the multi-core has become popular hardware, yet the traditional federate mechanism couldn´t utilize and schedule the CPU resource, which would limit the simulation performance. Then PFHF, Parallel Framework for HLA Federate, was designed and realized to solve the problem above. PFHF could combine and construct federate from simulation model components, perform simulation engine management, data distribution management, object management, component management and load balancing function, etc., then support the integrated execution environment based on multi-core and parallel technique. Several experiments proved that PFHF could utilize multi-core CPU adequately, and reduce the LSDSS execution time efficiently.
