A simulation component, oriented as a parallel framework for federate, was raised to facilitate federate development and improve execution performance of federate on multicore platform. Simulation components were employed to compose and assemble federates in parallel framework. With simulation engine management service, data distribution management service, object management service, component management service and load balancing of parallel framework, a multicore parallel environment was provided for simulation component, which also assured correct interactions between parallel federates and RTI. Experiments were carried out on the extra overhead introduced by parallel framework and performance comparisons between normal federate and parallel federate were made. Results showed that parallel framework fully exploited multicore processors with reduced execution time and improved performance of simulation system.
