我们演示了如何使用多计算机可以大大加快速度的行人运动模拟器的基础上的社会力量模型。我们的目标是开发一个模拟器,更新的位置,每一个行人在真实的时间,也就是说,每秒30次。我们通过使用多个处理器实现了这一目标。我们描述了我们的并行行人运动模型的设计,目前的基准测试结果表明,11个处理器可以更新10,000个行人的位置在大约1/50秒。并行算法是高度可扩展的,这意味着增加处理器将能够模拟更大的人群。
We demonstrate how the use of a multicomputer can greatly accelerate the speed of a pedestrian movement simulator based on the social forces model. Our objective is to develop a simulator that updates the position of every pedestrian in real time; that is, 30 times a second. We have achieved this goal through the use of multiple processors. We describe the design of our parallel pedestrian movement model and present benchmark results demonstrating that 11 processors can update the positions of 10,000 pedestrians in about 1/50 of a second. The parallel algorithm is highly scalable, meaning that adding processors will enable the simulation of even larger crowds.
