网格计算中任务分解和提交的研究

网格计算环境通过把若干个分散的异构计算资源虚拟为一个逻辑单元,使用户可以像使用一台计算机一样支配这些资源,从而达到提高资源利用率的目的。通过讨论使用Globus对应用程序进行任务分解和提交,得出如下结论：对于适合分解的应用程序,可以通过在虚拟计算环境进行分解后采用并行计算来提高应用程序的执行效率,但不适合实时性较强的应用。

Research on the Task Decomposition and Submitting in Grid Computing

The grid computing environment virtualizes several dispersive heterogeneous computing resources to a logic unit, which makes user to dominate these resources just like using a computer for the purpose of increasing the utilization rate of resources. Through the discussion on the task decomposition and submitting of the application program by using Globus, this paper draws the following conclusions： the application program suitable for the decomposition can be decomposed in virtual computing environment to increase the implementing efficiency of the application program by using parallel computing, but isn＇ t suitable for the application with stronger timeliness.
