面向服务的网格中,实现作业管理的应用程序一般采用多线程机制。这种方法相对于可以划分为相互独立子任务的网格作业而言,灵活性欠缺,而且会造成中心服务器负载过重、资源浪费、导致系统效率降低。针对这个问题,提出了一种“主任务分发-子任务签单”的机制实现作业管理,该机制能够较好地解决面向服务的网格中,具有此类特点的作业的管理方法存在的问题。
The application to implement job management in service-oriented grid usually adopts multithread scheme, which will result in the heavy load on central server and bring some other problems, such as resource wasting, efficiency reducing ,and so on. A new scheme of "main job dispense, sub-job sign" for job management is presented to solve the problems in this paper. This approach can handle the problem caused by general job management application method for service-oriented grid.
