Parallel Discrete Event Simulation (PDES) Systems demand a Declaration Management (DM) service and Data Distribution Management (DDM) service similar to those defined in HLA to realize model interoperability. In KD-PADSE, a high-performance PDES environment was implemented, and those services in a parallel structure based on event-scheduling using predication and object proxy techniques were realized. In an experiment carried out on a 10-node Linux cluster machine connected via 1Gbps switch Ethernet, 10 thousand attribute updates per second (wall clock time) was achieved in a synthetic benchmark test, which is 20 times larger than that of the same experiment without DDM services. The experiment proves the functionality and high performance of the implemented DDM service in a PDES environment.
