我们提出了一种克隆机制，可以对多个模拟期货进行评估。在一个共享内存的多处理器上对该机制的性能进行了实验分析和评估。在决策点动态克隆正在运行的并行离散事件模拟，以并发地探索不同的执行路径。通过这种方式，可以在游戏或战术和战略战斗管理等应用中执行假设和备选场景分析。一种名为虚拟逻辑过程的结构避免了克隆之间重复常见的计算，并提高了效率。无论克隆的数量(或执行路径)有多少，克隆的优势都会保留下来。我们用商业空中交通管制仿真的性能结果表明，克隆可以显著减少计算多个备选期货所需的时间。
We present a cloning mechanism that enables the evaluation of multiple simulated futures. Performance of the mechanism is analyzed and evaluated experimentally on a shared memory multiprocessor. A running parallel discrete event simulation is dynamically cloned at decision points to explore different execution paths concurrently. In this way, what-if and alternative scenario analysis can be performed in applications such as gaming or tactical and strategic battle management. A construct called virtual logical processes avoids repeating common computations among clones and improves efficiency. The advantages of cloning are preserved regardless of the number of clones (or execution paths). Our performance results with a commercial air traffic control simulation demonstrate that cloning can significantly reduce the time required to compute multiple alternate futures.
