In many scientific workflows, particularly those that operate on spatially oriented data, jobs that process adjacent regions of space often reference large numbers of files in common. Such workflows, when processed using workflow planning algorithms that are unaware of the application's file reference pattern, result in a huge number of redundant file(More)
The execution of scientific workflows in Grid environments imposes many challenges due to the dynamic nature of such environments and the characteristics of scientific applications. This work presents an algorithm that dynamically schedules tasks of workflows to Grid sites based on the performance of these sites when running previous jobs from the same(More)
