Abstract:The grid provides an integrated computer platform composed of differentiated and distributed systems. These resources are dynamic and heterogeneous. In this paper, a novel fault-tolerant grid-scheduling model is presented based on Stochastic Petri Nets (SPN) to assure the heterogeneity and dynamism of the grid system. Also, a new grid-scheduling strategy, the dependable strategy for the shortest expected accomplishing time (DSEAT), is put forward, in which the dependability factor is introduced in the task-dis… Show more
