RTI的线程模型在仿真系统中的研究与应用

RTI (Run-Time Infrastructure) is the implementation of Modeling and Simulation High Level Architecture. The following two problems will be encountered when we use multi-threaded RTI: the problem that how to ensure that the callback thread and the main simulating thread have mutually exclusive access to the shared data structures and the problem that RTI services can't be invoked in the callback functions no matter which RTI process model we choose. Firstly, the RTI process model and its influence on developing federates are argued, and then design a callback queue to buffer the callback events in order to solve the above two problems. Lastly, the implementation of the callback queue is given using C++.
