Embodiment 1
[0037] Preferred Embodiment 1: The HLA-based distributed simulation support platform of the present invention includes a high-performance computing cluster compatible with an RTI system unit, and the RTI system unit is deployed on the high-performance computing cluster. The HPC Compatible RTI System Unit supports the interoperability of simulation models on HPC clusters and PC networks.
[0038]On a high-performance computing cluster, federation members and cluster computing nodes have a one-to-many relationship. In this one-to-many relationship, one federation member is deployed on one computing node, or a federation member with high computing overhead is deployed on multiple computing nodes, and the parallel computing capability of the high-performance computing cluster is used to improve the computing efficiency of the federation members and the entire federation.
[0039] On the personal computer network, high-performance computing clusters compatible with RTI have RTI fun...
Embodiment 2
[0042] Preferred embodiment two: the architecture of TH_RTI is as follows figure 2 shown. The federation members are organized hierarchically. Federation members within the local area network are interconnected and interoperable through LRC (local RTI component, including libRTI and RTIA). On the upper layer of the LAN, the local RTI server (local RTI server) conducts unified management and communication through TH_RTI Gateway.
[0043] In TH_RTI, the interface function library libRTI provides compilation and connection interfaces for the development of federation members, and provides a series of services defined by HLA interface specifications for member developers. Currently provided is a C++ library. libRTI provides various service requests of HLA to federation members through RTI ambassador process (RTI::RTIAmbassador), and federation member process submits requests to RTI's local agent process RTIA through local socket. RTIAmbassador encapsulates the services provid...
Embodiment 3
[0046] Preferred Embodiment 3: The reflective memory card is a special network card, which embodies the idea of shared memory in a local area network. It is similar to other network cards in terms of communication function, and has its own characteristics in data transmission mechanism. The launch memory card is deployed on the optical fiber private network, sharing the same set of virtual addresses to achieve fast data synchronization. Such as image 3 It is a schematic diagram of deploying reflective memory cards in an optical fiber network. Data written to a reflective memory card is quickly copied to the same address in other shared memory on the network within 400 nanoseconds.
[0047] Schematic diagram of the integration of reflective memory network and TH_RTI by Figure 4 Given, the service interface of federation members is uniformly provided by TH_RTI. For those involving small data interaction and frequent calls, such as creating a federation, joining a federati...
