Sharing science in the ‘collaboratory’

International Science Grid This Week
October 17, 2012

Ewa Deelman, principal investigator of the Pegasus Workflow Management System, and Michael McLennan, director of the HubZero platform, explain how they are working together to aid scientific research.

Over the past several years, the US National Science Foundation has been funding the development of collaborative web sites or ‘collaboratories’ and scientific workflow technologies. Many communities have adopted the HUBzero platform to create collaboratories called ‘hubs’ where they can share ideas, models, experiences, publications, and data in pursuit of research and education. Scientists have also been using the Pegasus Workflow Management System (WMS) to manage complex analyses running on their campus and on large-scale cyberinfrastructure, such as the Open Science Grid, DiaGrid, and XSEDE.

Over the last few months, a joint team of HUBzero developers (Steven Clark and Derrick Kearney of Purdue University, Indianna, US) and Pegasus developers (Mats Rynge and Karan Vahi, University of Southern California, US) together with domain experts Frank McKenna of the University of California, Berkeley, US, and Linas Mockus, also of Purdue University, have integrated the two technologies. Now, the latest HUBzero software, released at the recent HUBbub 2012 conference in September, includes Pegasus WMS as an integrated system.
