大型强子对撞机ATLAS实验的模拟软件正用于大型强子对撞机计算网格上的事件大规模生产。这种模拟需要许多组件，从模拟粒子碰撞的发生器到模拟各种探测器和触发器响应的软件包。所有这些组件都集成在ATLAS仿真基础设施中。在本文中，该基础设施进行了讨论，包括支持检测器的描述，接口的事件生成，并结合GEANT4模拟的各个检测器的响应。还描述了允许软件验证、性能测试以及针对已知物理过程验证模拟输出的工具。
The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.
