We know it is a dream a few years ago, but the reality is that today, the Grid is so-called "work in progress", with the underlying technology still in a prototype phase, and being developed by hundreds of researchers and software engineers around the world. The Grid is attracting a lot of interest because its future, even if still uncertain, is potentially revolutionary. In the environment of resources sharing, the conditions of resources, like CPU loading, memory using rate and etc. in all coordination nodes vary dynamically that will influence the whole efficiency of grid. Therefore, we need an optimal scheduling for sharing of dynamical resources and design the best plan for coordinating nodes’ resources. That will not only make resources using and sharing much more effectively and flexibly, but also will raise the total computing efficiency of grid. In this study, we build up a dynamic management model, aimed at the grid environment that the nodes’ resources change dynamically and continually. In this model we also design and use bayes’ decision theory to find the lowest cost energy evaluation for each coordinating nodes’ resources, we can take advantage of the efficiency analysis for various nodes cooperating and computing to reduce the entire computing time and raise the total computing efficiency of grid.
