"What's New in XSEDE" (previously "News from XSEDE") is a monthly e-newsletter providing information on scientific discoveries made possible by the Extreme Science and Engineering Discovery Environment and the people, places and programs involved. XSEDE is a five-year high-performance computing project supported by the National Science Foundation.

Computer models help shape plans in event of widespread flu outbreak

Computer models are being used to create simulations showing how pandemic diseases spread and helping public health officials create better-informed, more effective plans for such outbreaks. In a recent Webinar for the University of Pittsburgh Graduate School of Public Health, Pittsburgh Supercomputing Center (PSC) and XSEDE scientist Shawn Brown discusses the role of computational modeling in informing policy interventions in pandemic influenza. The image below shows the predicted spread of a pandemic of H1N1 influenza in the Washington, D.C., area based on the computer models. Blue indicates the lowest number of infected cases per square mile and bright red shows the highest number.

In 2009, Brown's models helped assess the spread of influenza and influenced public health policy.

SDSC's 'big data' expertise aids genomics research

As science problems grow ever more complex -- especially in this age of DNA and RNA sequencing -- the amount of data generated is compounding the situation. The San Diego Supercomputer Center (SDSC) has developed expertise in providing both the supercomputing power and the management of "big data," allowing researchers to use data more effectively to advance science.

Map of role-playing gamers' chats during a game.NCSA helps researchers harness big data in gaming and census analyses

Dmitri Williams, a University of Southern California researcher, is working with the National Center for Supercomputing Applications (NCSA), including XSEDE advanced support staff member Dora Cai, to learn more about human behavior by examining huge amounts of data from online role-playing games. The graph shown here represents each time two players chat with one another in a game. By examining the gamers' strategies and interactions, researchers are hoping to answer behavioral questions and perhaps correlate online activities with behavior in the real world.

In another data-intensive project, XSEDE resources at NCSA are helping researchers establish a system of digitizing U.S. Census data, including hand-written information, making it searchable and retrievable.

Bubbling beds and biofuels

By studying simulations that explore the intracacies of how fluidized bed reactors work, scientists searching for alternatives to non-renewable fuels are able to investigate new possibilities. The National Institute for Computational Sciences (NICS) is helping make the Cornell and National Renewable Energy Laboratory (NREL) team's experiments and simulations possible.

A tree of life grows in Texas

At the Texas Advanced Computing Center (TACC), scientists are using the Ranger supercomputer to create a more accurate evolutionary history by examining multiple species of living organisms at the genetic level. It is a complex task that "can take a very long time -- weeks to months to years of computational time," according to Tandy Warnow, computer science professor at The University of Texas at Austin and a Guggenheim Fellow. But with the help of TACC supercomputers, software from Warnow and her team is improving the process and opening doors for future discovery.

Crater caused by explosion during transport of volatile materials.Mobile mayhem

Analyses of accidents involving the transportation of explosives are expected to help increase the safety of future transports, thanks to simulations done on the Kraken supercomputer at NICS. Scientists are examining the simulations in ways and on scales that have not been done before to determine how to decrease, and perhaps eliminate, the possibility of detonation of the explosives as they are trucked around the country. Pictured here is the crater resulting from the August 2005 detonation in Spanish Fork Canyon, Utah, of more than 35,000 pounds of explosives.

Collision chemistry

A study of chemical reactions at the molecular level, facilitated by supercomputers Ranger and Lonestar at TACC is helping further explore the complexities of the subject and add to the body of knowledge. By simulating reactions on the computers, scientists are discovering ways that may allow for more control over reactions in the future, with revolutionary implications for industries such as medicine and manufacturing.
