Research of Grid Scheduling Algorithm Based on P2P_Grid Model

Task scheduling is an integrated component of grid computing among the key technology of the grid. P2P_Grid model, a new resource manage model of grid is brought up in this paper. In this model, we make some super-peers to join grid, it divides the grid into corresponding sub-grid. Each super-peer composes one local grid system and answers for dealing with events of a local Grid that it belongs to; these Super-Peers in different local Grid are equal and they change messages by P2P mode. A modified Grid scheduling algorithm is drawn out based on P2P_Grid model environment and the idea of traditional Min_min scheduling algorithm. At last, the new algorithm is compared with traditional Min_min algorithm by simulate experimentation, it shows that the new algorithm has a better quality of system load balancing and the utilization of system resource.
