Description
Summary:Applications that span multiple virtual organizations (VOs) are of great interest to the eScience community. However, recent attempts to execute large-scale parameter sweep applications (PSAs) with the Nimrod/G tool have exposed problems in the areas of fault tolerance, data storage and trust management. In response, we have implemented a task-splitting approach, which breaks up large PSAs into a sequence of dependent subtasks, improving fault tolerance; provides a garbage collection technique, which deletes unnecessary data; and employs a trust delegation technique that facilitates flexible third party data transfers across different VOs.
