HP-HLA/RTI prototype oriented on shared memory environment

To improve the running performance of simulation system, and combined with the advantage of multi-core environment and shared common random access memory network, research on High Performance Run Time Infrastructure based on Shared Memory (HP-RTI-SHM) system becomes a hot topic nowadays. However, most existing relative research focuses on communication optimization, and other aspects need further study. Based on open source project SHM-CERTI and combined with shared memory parallel environment characteristic, main work includes: (1) an optimized software realization architecture; (2) a parallel optimized computing method for Lower Bound Time Stamp in time management; (3) a parallel optimized data interaction method between federates; (4) a simulation task monopolistic scheduling method based on real-time operation system; (5) COSIM-RTI-SHM prototype is preliminary realized. The performance test comparing with SHM-CERTI shows COSIM-RTI-SHM improves simulation advance speed and improves simulation data interacting speed and throughput.
