Efficient scheduling in decentralized grid environment

Abstract

The grid computing enables wide area resource sharing and collaboration It is a fast emerging distributed technology Based on scheduling of computational jobs for different resources the computational grid can be classified into two type s namely centralized grid and decentralized market like grid Both the types involve sharing and newlinecollaboration among different resource providers and consumers with centralized or decentralized scheduling schemes newlineThe key difference between the two schemes lies in scheduling newlinedecision In the centralized grid the grid system makes decisions as follows newline Which job is to be executed newline When is it to be executed newline Which resource can be utilized newlineIn the decentralized market like grid such decisions are made by concerned resource provider consumer to share the data among different participants efficiently with less unit price This work which is based on decentralized market like grid comprises of an association of jobs and resources a development of Economic Demand Model with reasonable pricing scheme and an Optimistic Heuristic Model The association of global local jobs and resources in this work allows the grid to communicate each other effectively by exchanging the jobs and resources newline newline
