随着并行空间计算任务的不断增多，传统的MPI服务器集群容易出现排队时间长、拒绝服务甚至系统瘫痪等情况。利用虚拟化、作业调度等技术构建云计算平台上的MPI虚拟集群可以提升MPI服务性能，从整体上缩短排队等待的时间，从而使得服务质量QoS(Quality of Service)得到保证。通过在OpenStack上部署MPI虚拟服务器集群、利用Torque实现MPI作业的调度管理的基础上，使用DEM(Digital Elevation Model)等高线生成算法组成MPI作业队列，对传统MPI物理集群与MPI虚拟集群进行性能对比分析，结果显示了云计算平台上MPI并行环境在面对大量任务作业时的优势。
隨著併行空間計算任務的不斷增多，傳統的MPI服務器集群容易齣現排隊時間長、拒絕服務甚至繫統癱瘓等情況。利用虛擬化、作業調度等技術構建雲計算平檯上的MPI虛擬集群可以提升MPI服務性能，從整體上縮短排隊等待的時間，從而使得服務質量QoS(Quality of Service)得到保證。通過在OpenStack上部署MPI虛擬服務器集群、利用Torque實現MPI作業的調度管理的基礎上，使用DEM(Digital Elevation Model)等高線生成算法組成MPI作業隊列，對傳統MPI物理集群與MPI虛擬集群進行性能對比分析，結果顯示瞭雲計算平檯上MPI併行環境在麵對大量任務作業時的優勢。

With the number of the MPI tasks scheduled in the queue rising steadily, to certain tasks, such phenomena will be easi-ly to appear, e.g., waiting long time, being delayed or even denied to service. Utilizing the virtualization, job scheduling and relat-ed technologies in the field of cloud computing can enhance the QoS (Quality of Service) in the MPI server cluster, and the men-tioned problem would be solved to a certain degree. In the experiments, some Geo-spatial MPI parallel tasks, the parallel contour generation algorithm from DEM with MPI, are scheduled by Torque PBS to the different computing platforms respectively, i.e., the combined platform with cloud computing (OpenStack) and parallel computing, and the traditional parallel computing plat-form. From the simulation tests results, it can be easily found that the combined computing environment has dominant advantag-es than the traditional finally.
