Workflow Management for Symbolic Grid Services

The development of software systems for scientific exploration and discovery through computation has an important issue to address: the management of underlying computational steps. To support composition of Web and Grid services, standard workflow languages and workflow execution engines were built but management capabilities are not yet entirely explored. In the context of Grid services, we propose a solution for controlling the execution of workflows without the assistance of a user interface oriented workflow engine. We also investigate the capabilities that our solution may offer for related features such as dynamic retrieval of partial results, steering and provenance.
