实现网格中含有依赖任务调度的GS算法，其中根据任务在各个机器上的执行时间和任务之间的依赖关系来计算出任务的调度顺序-The realization of the grid containing the GS-dependent task scheduling algorithm, in which the task in accordance with the implementation of the various machines on time and task-dependent relationship between the task scheduler to calculate the order of
