The chief White House adviser on advanced manufacturing science and technology, the United Kingdom’s director for digital social research and the leader of the Pegasus project at the University of Southern California, which makes it easier for researchers to work with high-performance, grid and cloud computing resources, are among the speakers set for HUBbub 2012. The conference Sept. 24-25 focuses on HUBzero, a Purdue University-developed ready-made cyberinfrastructure for research and education. To register, go to: http://hubzero.org/hubbub.
The Pegasus Workflow Management System, developed by Ewa Deelman and her team at the University of Southern California, simplifies workflow building so researchers can concentrate on research instead of computer programming. In addition to Deelman, speakers set for HUBbub 2012 include Thomas Kurfess, assistant director for advanced manufacturing in the U.S. President’s Office of Science and Technology Policy, and David De Roure, the United Kingdom’s national strategic director for digital social research and leader of the myexperiment.org social website for sharing scientific workflows.
In 2011, the HUBbub conference attracted people from as far away as South Korea and South Africa, along with U.S. institutions spread from New York to Oregon and Florida to Wisconsin. The event includes sessions for researchers, educators and practitioners already using a hub who want to learn more, and for those curious about hubs or interested in employing the new open source release of HUBzero to establish their own.
“Integrating Pegasus into HUBzero makes it available to a large number of scientists who rely on the HUBzero infrastructure to do their work,” Deelman says. “Pegasus in a hub can run workflows on a variety of environments including grids like the Open Science Grid, XSEDE, and clouds like FutureGrid and Amazon. We hope to continue to work with the HUBzero community to enhance the Pegasus capabilities as users become familiar with our workflow tool.”
Michael McLennan, chief architect of HUBzero at Purdue, says Pegasus in HUBzero is like bringing high-performance computing to the masses.
“There are more than 40 hubs based on the HUBzero toolkit serving many areas of science and engineering and other research fields, from nanotechnology to pharmaceuticals to cancer research to biofuels,” McLennan says. “They will all benefit from this.”
Originally developed to power Purdue-based nanoHUB
, HUBzero is a software platform used to build websites for scientific and other kinds of research as well as educational activities. Besides nanotechnology, hubs now support users in fields such as earthquake engineering, global engineering education, microelectromechanical systems, volcanology, professional and research ethics, environmental modeling, and the bonds between humans and companion animals.
A major HUBzero feature is its ability to deploy computational research codes, and visualize and analyze results, all through a familiar Web browser interface. It makes posting tools about as easy as posting a YouTube video. Built-in social networking features help create communities in almost any field or subject matter and facilitate communication and collaboration, distribution of research results, training and education. Moreover, the platform has a growing set of data management capabilities.
Other scheduled speakers at HUBbub 2012:
Andy Burnett, CEO of Knowinnovation Inc., which focuses on mechanisms to accelerate scientific innovation and former co-director of the Centre for Creativity at the Cranfield School of Management in the United Kingdom.
Noshir Contractor, Northwestern University, whose research focuses on social and knowledge networks in a wide variety of contexts including business, translational science and engineering, public health and virtual worlds.
Nancy Wilkins-Diehr, co-principal investigator of the National Science Foundation's XSEDE cyberinfrastructure project and co-director of the XSEDE Extended Collaborative Support Services program, which works to solve challenging science and engineering problems through cyberinfrastructure.
Jarek Nabrzyski, director of the University of Notre Dame Center for Research Computing, which has developed numerous Web-based science portals or gateways, including some using HUBzero.
