| 摘要: |
| 在并行离散事件仿真系统中实现仿真模型间的互操作机制需要引入类似HLA中定义的声明管理(DM)和数据分发管理(DDM)服务。我们开发的KD-PADSE高性能并行离散事件仿真环境采用谓词断言和对象代理方法在面向对象的并行离散事件仿真系统中实现了基于平行结构和事件调度机制的声明管理（DM）和数据分发管理（DDM）服务。在以千兆以太网互联的10节点Linux集群计算机上，采用DDM机制后仿真模型每秒（物理时间）可以进行1万次属性更新，是没有采用DDM机制时的20倍，在功能性和性能上验证了该DDM机制在并行离散事件仿真系统中的适用性。 |

| Abstract: |
| 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. |
