云计算为高能物理实验数据处理提供了新的技术手段。然而，在传统的作业管理系统中，每个队列的资源是固定的，资源的使用是静态的。为了让物理学家使用起来简单透明，我们开发了一个虚拟集群系统（vpmanager）来集成IHEPCloud和不同的批处理系统，如Torque和HTCondor。Vpmanager根据作业队列提供动态的虚拟机调度。BES III的用例结果表明，资源效率大大提高。
Cloud computing provides a new technical means for data processing of high energy physics experiment. However, the resource of each queue is fixed and the usage of the resource is static in traditional job management system. In order to make it simple and transparent for physicist to use, we developed a virtual cluster system (vpmanager) to integrate IHEPCloud and different batch systems such as Torque and HTCondor. Vpmanager provides dynamic virtual machines scheduling according to the job queue. The BES III use case results show that resource efficiency is greatly improved.
