摘　　要：网格计算是构筑在互联网上的新兴技术,在提供的资源、功能和交互性方面比互联网更多更强。集中式任务管理网格以单机统一调度,具有集成性强和出错率低特点。使用特定有关算法,可进行最佳工作单元分配。通过基于XML的Web Service的调度原语,可进行跨平台的网格集中式任务管理的调度,由监工线程定时动态地保证调度的合理性。通过修改任务排序算法,可适应不同目的的调度需求,以适应局域网、Intranet和Internet上网格计算的调度。Grid compute is a new, state-of-the-art technology that by making use of internet and intranet. However the grid compute approach is more powerful and better than conventional internet in providing computing source, functionality, and interactivity. Unlike a distributed grid compute, the concentrated grid compute task do schedule function with a single unit, which ensured a high integrated system, and minimized the error that may happen. The optimum of work unit dispatch could be obtained when a suitable algorithm was used in operation. By having web service, and XML, the schedule function for concentrated grid compute task could be operated between multiple platforms. The consistence of schedule is supervised by a monitor program periodically in real time. The schedule function could be applied to different environment grid compute, such as LAN, intranet, and internet by modifying the task sort algorithm.
