A New Algorithm Based On The Grid Medel And Its Scheduling Protocol Resource Reservation Technology

Resource management of grid system is one of the most important technologies, and it is of great theoretical practical value for the development of grid computing, location, organization, scheduling, allocation, confirming the discovery process, creating and preparing the necessary resources.It provides advanced management features and concepts, the clusters can be used as a single resource, administrator according to predetermined criteria, through resource management software, ensure the reasonable configuration of resource and use, achieves resources sharing.The main work of this paper is based on the traditional hierarchical scheduling model (P2P-Grid), proposes a new grid structure model (Group-Grid), to solve the traditional grid structure model in the surviving several main problems.This paper presents the model cf Group-Grid, is the grid resources according to the resource provider is divided into different compartments.Model of service discovery module to realize the purpose of quick search resources.Improved P2P-Grid using pan Hong Fa led to the network load increases, the disadvantage of the long search cycle.But also has strong expansibility, easy adjustment etc.Based on the structure model of resource reservation strategy, is available in the general reserve strategy based on task, put forward block, reservation cancel and reserved level concepts, so as to ensure the reliability and flexibility of the reservation of resources, and improve the success rate of Resource Reservation Reservation and customer QoS.In addition, the traditional resource reservation algorithm can balance the network overall resource utilization is insufficient, the existing balance tasks of resource reservation algorithm, this paper proposes an improved resource reservation algorithm, the immediate task is transformed into the reservation task submitted to the entire network to reduce the immediate task of the average waiting time, and can realization of whole network load balance, improve the utilization rate of resources in grid.The simulation results show that, the resource reservation strategy than the old strategy in the success rate improved by15%, in the cyber source utilization rate is improved by5%.
