Abstract

Effective task scheduling mechanisms for Grids must address the dynamic and heterogeneous nature of the system by allowing rescheduling and migration of tasks in reaction to significant variations in resource characteristics. Migration may be invoked when the cost of the migration itself is outweighed by the global time saved due to execution at the new site. We extend our previous results in this area by considering the maintenance of a collection of reusable copies of the results of completed tasks. We show how to reuse such copies to improve overall application makespan. We present the Grid Task Positioning with Copying facilities GTP/c system. We compare the performance of GTP/c with our previous model GTP and DLS/sr, an adaptive version of the dynamic level scheduling static method.
