Grid Resources And Operations Management Techniques

Grid is a new-type computing platform and technology developed with the Computer and network. It enables the sharing of various heterogeneous resources and coordinated working of geographically distributed resources, thus grid set up a huge virtual supercomputer. Resources management is the core and difficulty of grid. This thesis discussed the grid concept, and introduced a popular grid architecture: five hourglasses model. On this basis we study emphatically the grid resources management technology, job management technology, and so on.This paper proposed a resource allocation algorithm based auction model, which is a computational economy model. The algorithm simulated the auction of real life, so grid users can use resources fairly and rationally. This algorithm can meet different users' demands of optimizing running time or budget, and at the same time maximize the grid resources owner's profit. It helps grid to develop by introducing into market mechanism, and in this way resource providers will supply more and better grid resources. In the article we also analyzed shortcomings of the algorithm and provided solutions to improve it.This thesis also introduced a local job management system based cluster, and then used Gloubus tool to construct a grid JMS prototype which supplied this cluster. This grid prototype system realized remote job submitting and management. The thesis proposed a multi-layers job scheduling method by which jobs first are scheduled in grid system, and then be submitted to local JMS for second scheduling. Thus we can expand the scale of cluster easily and save manager node from performance bottleneck problem, because there was only one manager node in cluster. At last we designed a test program used to analyze the performance of the system.
