| 摘 要： | 复杂系统的协同仿真中需要运行支撑软件RTI(Run Time Infrastructure)来解决异构模型、异构仿真软件间的数据交互的问题.但RTI的TCP/IP通信机制却无法使得HPC(High Performance Computer)的高速网络Infiniband(IB)在仿真中发挥最大的优势.针对这一问题,本文提出在IB网络架构下基于RDMA(Remote Direct Memory Access)通信机制对RTI进行优化,并以开源HLA项目CERTI软件为基础,研制运行在IB网络下的IB-CERTI软件,最后在不同网络环境下进行对比实验,实验结果证明了IB-CERTI软件在仿真通信中的高效性,特别是仿真邦员间的交互数据量越大,越能提高仿真数据传输效率.

| Abstract: | Collaborative simulation of complex systems need Run Time Infrastructure (RTI)software to solve the problem of data exchange between heterogeneous models and heterogeneous simulation software.But the TCP/IP communi-cation mechanism of RTI cannot make HPC High Speed Network in the simulation which is the strongest advantages of In-finiband (IB).To solve this problem,this research designs the RTI network optimization based on RDMA communication mechanism,which through the module decomposition and network optimization of CERTI software in open source HLA pro-ject,made the IB-CERTI software which run on IB.Eventually,in the experiment of comparison RTI software network per-formance under different network environment,the experiment results show the efficiency of the IB-CERTI software under simulation communication,especially the larger amount of interactive data between simulation federates,the more efficiency in improving simulation data transmission. |
