Dynamic task scheduling of the grid workflow

The technique of grid, becomes the focus of the research gradually. As the workflow in grid environment, grid workflow has some characteristics itself, so that it can´t inherit traditional workflow straightly. Hence, in this article, we put forward a new task scheduling algorithm for the grid workflow. By carrying out the distributed booking and assigning of the resource, computing the time of implement intelligently, and building the scheduling sequence dynamically, it achieves the optimization of the scheduling in view of the whole grid system.
