Research on the Grid-server Auto-switching

在计算网格上，为了提供应用程序能够稳定运行的环境，需要根据服务器的执行状态自动切换要使用的服务器的机制。本研究针对网格服务器自动切换机制的实现，在提出将任务分配给服务器的调度技术的同时，开发了具有网格服务器自动切换功能的网格中间件。

On a computational grid, to provide the environment where application programs can run stably, the mechanism in which servers to be used are automatically switched according to the execution status of the servers is required. In this research, aiming at realization of the automatic switching mechanism of grid servers, while proposing the scheduling techniques which perform task assignment to servers, the grid middleware which has a grid-server auto-switching function was developed.
