摘　　要：气象卫星地面应用系统中服务器规模庞大,设备种类多样,如何充分利用这些计算资源已经成为一个关键性问题,而虚拟集群可以将这些能力各异的服务器进行有机整合。本文提出一种基于重要度的虚拟集群资源调度方法。首先,根据服务器负载能力确定资源域;然后,计算出服务器负载粒度,分辨度和重要度;最后,以服务器负载重要度为权值进行任务的分配。仿真实验结果表明,该方法可以有效提高集群整体的资源利用率和负载能力。The large number and size of servers in meteorological satellite terrestrial applications have become a key issue to make full use of these computing resources. However, virtual clusters can organically integrate these different capabilities. So, this paper proposes a virtual cluster resource scheduling method based on importance. Firstly, according to the server load capacity, the resource domain is determined. Then, the granularity, resolution and importance of the server load are calculated. Finally, the task is assigned with the weight of the server load. The simulation results show that this method can effectively improve the overall resource utilization and load capacity of the cluster.
