PROGENIA: An Approach for Grid Interoperability at Workflow Level

This paper addresses the problem of simulating complex large-scale experiments by using the PROGENIA WorkFlow Management System (WFMS), developed in the ProGenGrid (Proteomics and Genomics Grid) research project at the University of Salento, deployed and tested in a real Grid-based Problem Solving Environment for Bioinformatics named LIBI (International Laboratory of Bioinformatics). PROGENIA aims to achieve interoperability at workflow level, supporting the deployment of a workflow on different Grids based on Globus, gLite and Unicore middlewares. By using specific adapters, the workflow engine acts as a meta scheduler, submitting the jobs on different grids. The meta scheduler selects the available resources from a list of resources, previously configured by the PROGENIA administrator, by using the interfaces of the PROGENIA editor to configure a grid (Users admin, Virtual Organization, Resource and Software Management). PROGENIA will allow domain researchers to share and reuse their scientific workflows across distributed computing infrastructure. PROGENIA has been tested in several Bioinformatics case studies. In particular a test case related to the protein multi-alignment, executed on gLite and Globus middleware will be presented.
