Abstract: Through the research of the grid computation in the resources coordination dispatch mechanism, according to this mechanism’s resources coordination assignment demand, this paper proposes a take Globus Toolkit as the platform based on the grid computation distribution coordination computation model. In the scheduling mechanism’s tendering mechanism based on economic model, this paper gives the price function of a more comprehensive model and the corresponding job completion time prediction model, the design cost function model provided by the initiative of resources, makes resource allocation more reasonable and fast. Meanwhile, it also gives a backup job scheduling based on fault-tolerant mechanisms in a distributed computing model.
