To obtain high-performance simulation supporting environment that can satisfy the need of argument simulation and with super real-time operation ability, according to the characteristic of high-performance distributed simulation, a software architecture and components of integrated environment is researched for developing and running high-performance distributed simulation based on high level architecture (HLA). It Mainly includes the integrated development environment and running-monitoring management environment, and provides an integrated environment for the development, test, integration, initialization, execution, monitoring, and management of high-performance distributed simulation. The function design and key technologies of each component, especially HPC-RTI, are described in detail. A certain equipment system simulation experiment was carried out, and the experimental results show that the efficiency of large-scale simulation system is improved by 17.8 times.
