Abstract

The recent enthusiasm in grid computing has given rise to a large amount of research on resource scheduling techniques for tasks in a workflow. Most of the work on resource scheduling is aimed to minimize the total response time for the entire workflow. In this paper we propose a new balanced scheduler that resolves a workflow using the idle cycles of each resource of the Grid. The workflow is based on iterative tasks that usually appear in optimization problems. Experimental results using balanced load scheduler show that it is possible to obtain an improved use of the resources in the Grid thorugh assigning more tasks to the resources that have more idle cycles. This strategy enables to adapt the length of a task to the computing capacity of each resource at any given moment. Furthermore, this scheduling strategy enables to execute all the tasks in a shorter time.
