Abstract
A large-scale simulation in e-Science experiments can be modeled by using a workflow. The ProGenGrid Workflow Management System is being developed at the University of Salento in Lecce since 2004 and consists of an editor for designing the experiment and an engine for scheduling the jobs in a Computational Grid. The initial version was based on wrapping the bioinformatics tools as Web Services and scheduling job execution on the Grid by using an opportune engine. Then the engine was optimized to support batch, parameter and MPI jobs by using the Globus Toolkit. This component was developed as part of the Grid Resource Broker project. In this paper, we present the latest advances regarding the editor’s new features such as on line monitoring, and the engine’s support for scheduling jobs on other grid middleware such as gLite and Unicore.
