| Abstract: | In order to solve the problems existing in current grid environments,such as the difficulty of application development and the complexity of management,a new tree-based grid environment named TGrid is proposed.TGrid supports the high-performance computing,the subject-oriented resource sharing and the requirement mode-ling in the next generation.After analyzing the characteristics of TGrid and the key problems in TGrid implementation,some key algorithms for the tree building,the dynamic reconfiguration of tree and the task distributing are presented.Moreover,the dynamic load-balancing algorithm for large-scale applications in TGrid is specially described in detail.Simulated results show that the proposed algorithm is effective. |
