【摘要】 任务调度和管理是遥感卫星数据地面预处理系统设计中的核心技术。如何对于新型的基于并行机群平台的遥感卫星数据预处理系统进行有效的任务管理和调度,将对系统的可用性、可扩展性以及性能等产生很深的影响。文章讨论一种成功应用于通用高性能卫星地面预处理系统(GHIPS)中的、基于机群平台的任务管理与调度技术,并用于指导为高性能遥感数据处理平台提供一种通用的任务管理与调度解决方案。更多还原

【Abstract】 Task scheduling and management is always the key technique in the remote sensing satellite ground pre-processing system.The way of scheduling and management can heavily affect the availability,extensibility and performance of the system,which is especially obvious in parallel and cluster-based pre-processing platforms.In this paper,a new cluster-based task scheduling and management strategy which is successfully applied in a general high performance pre-processing system(GHIPS) will be discussed after a simple analyzing of the strategies of the current pre-processing systems.And try to offer a general task management and scheduling solution for high performance remote sensing data processing platforms.更多还原
