Sept. 6 — The latest version of HUBzero, an open source "cyberinfrastructure in a box," with new capability to create collaborative "project" areas within a hub, federated identity management, email integration, design improvements, and dozens of other new features will be released at HUBbub 2012, the annual HUBzero users conference.
"There are more than 40 hubs based on the HUBzero toolkit serving many areas of science and engineering and other research fields, from nanotechnology and cancer treatment to earthquake engineering and the bonds between human and companion animals," says Michael McLennan, chief architect of HUBzero at Purdue. "They will all benefit from this."
The two-day HUBbub 2012 conference for researchers, practitioners, educators and IT professionals engaged in building and using cyberinfrastructure is Sept. 24-25 at the IUPUI University Place Conference Center, 850 W. Michigan St., Indianapolis. For more information and to register, go to: http://hubzero.org/hubbub. HUBbub 2012 includes sessions for both people already using a hub who want to learn more, and for those curious about hubs or interested in employing the open source release of HUBzero to establish their own.
Among the highlights in the latest version of the HUBzero software:
Originally developed for nanoHUB.org, HUBzero is an open source software platform used to build websites for scientific and other kinds of research and for education and training. Such websites are sometimes referred to as "collaboratories" supporting "team science." HUBzero calls them "hubs" because the sites become a focal point for user communities. Today, hubs are serving virtual communities in translational health care, engineering education, microelectromechanical systems, volcanology, professional and research ethics, environmental modeling and biofuels, among other topics.
A major HUBzero feature is its ability to deploy computational research codes, and visualize and analyze results, all through a Web browser. It makes posting tools about as easy as posting a YouTube video. Moreover, the platform has a growing set of data management tools. Built-in social networking features create communities in almost any field and facilitate communication and collaboration, distribution of research results, training and education.
HUBbub 2012 also will highlight a new organization, the HUBzero Foundation, that promises to make HUBzero even more accessible and to expand the platform's already considerable capabilities. The new HUBzero Foundation — open to any academic institution, non-profit organization, or corporation — offers a number of benefits to members, including access to the latest HUBzero features and bug fixes before they're available in the open source releases and a role in setting the roadmap for future development.

In 2011, HUBbub attracted more than 100 people from as far away as South Korea and South Africa, along with US institutions spread from New York to Oregon and Florida to Wisconsin.
The ever-growing complexity of scientific and engineering problems continues to pose new computational challenges. Thus, we present a novel federation model that enables end-users with the ability to aggregate heterogeneous resource scale problems. The feasibility of this federation model has been proven, in the context of the UberCloud HPC Experiment, by gathering the most comprehensive information to date on the effects of pillars on microfluid channel flow.
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
Frank Ding, engineering analysis & technical computing manager at Simpson Strong-Tie, discussed the advantages of utilizing the cloud for occasional scientific computing, identified the obstacles to doing so, and proposed workarounds to some of those obstacles.

The study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
04/02/2012 | AMD | Developers today are just beginning to explore the potential of heterogeneous computing, but the potential for this new paradigm is huge. This brief article reviews how the technology might impact a range of application development areas, including client experiences and cloud-based data management. As platforms like OpenCL continue to evolve, the benefits of heterogeneous computing will become even more accessible. Use this quick article to jump-start your own thinking on heterogeneous computing.
