Abstract

The world-widely distributed computers are connected to establish a global source of processing power, called a computational grid. While the computational grid provides enormous processing power, hurdle stone in effectively utilizing the power is that, successful execution cannot be guaranteed due to the heterogeneous nature of the resources .Job replication technique is to guarantee the successful execution of the job where the job is executed in more than one resource. A novel job replication technique is described in this paper in which the replica number is derived based on the trust factor. The trust factor is estimated based on the reputation report from the users who submitted their jobs to the resource. This approach optimizes the replication and improves the performance of the system.

Keywords
