Research On Resource Management In Grid Environment

Grid is a new emerging technology, which is based on Internet. It provides more widespread resources sharing for the dynamic change VO's members, by integrating computation resources, the memory resources and the correspondence resources, which are distributed on network. The grid completes the big work task through collecting distributed resources, and resources sharing are one method of collecting resources. The grid provides the visible interface to the user by highly abstracting the resource, which is distributed on network. Grid is dynamic and diverse, and that needs the dynamic consideration in grid resources management.Firstly, on the basis of the studies of grid architecture, MDS, RLS, and combined with the requirement of data management of Oil Field, this thesis advances a platform model of distributed data management based on grid. Secondly, it focuses on two points of key technologies involved in the model. One is grid resources monitoring and discovery, the other is Replica Location Services. In resources monitor and discovery model research process, a method of aggregating information based on MDS is advanced, and a prototype of MDS query client is implemented. Finally, based on the model which proposed has designed the distributed data management system, and has implemented the partial functions in the prototype system.It is proved that the distributed data management model by the cooperation of each part could have the problem of the great data accessing managed. The replica resources management has been completed in grid.
