  2. TeraGrid: Integrating NSF Cyberinfrastructure Buffalo Wisc Cornell Utah Iowa Caltech USC-ISI UNC-RENCI UC/ANL PU NCAR PSC IU NCSA ORNL SDSC TACC TeraGrid is a facility that integrates computational, information, and analysis resources at the San Diego Supercomputer Center, the Texas Advanced Computing Center, the University of Chicago / Argonne National Laboratory, the National Center for Supercomputing Applications, Purdue University, Indiana University, Oak Ridge National Laboratory, the Pittsburgh Supercomputing Center, and the National Center for Atmospheric Research.

  3. TeraGrid Vision • TeraGrid will create integrated, persistent, and pioneering computational resources that will significantly improve our nation’s ability and capacity to gain new insights into our most challenging research questions and societal problems. • Our vision requires an integrated approach to the scientific workflow including obtaining access, application development and execution, data analysis and management, and collaboration.

  4. TeraGrid Objectives • DEEP Science: Enabling Petascale Science • Make Science More Productive through an integrated set of very-high capability resources • Address key challenges prioritized by users (tera - 10^12; peta - 10^15) • WIDE Impact: Empowering Communities • Bring TeraGrid capabilities to the broad science community • Partner with science community leaders and educators • OPEN Infrastructure, OPEN Partnership • Provide a coordinated, general purpose, reliable set of services and resources • Partner with campuses and grids

  12. Modeling Information Processing and Public Opinion How do people assess political candidates? How do campaign events and new information change their views? Sung-youn Kim, University of Iowa, and Milton Lodge and Charles Taber, Stony Brook University, New York, saw gaps between existing models and empirical findings integrated both cognitive and affective information-processing theories into a computational model that simulates how voters’ political opinions fluctuate during a campaign. Using data from the 2000 National Annenberg Election Survey (NAES), they constructed virtual voters, each with a unique mindset. Campaign messages were gleaned from news accounts and reduced to simple sentences (e.g. "Bush said Gore is dishonest" or “Gore said Bush is anti-abortion”). The computational model parses each sentence, retrieves relevant concepts from the long-term memory of each agent, and updates each agent's knowledge and attitudes accordingly. Using 100 agents, this simulation was repeated 100 times, returning results that accord well with the actual 2000 polling data. Because of this complexity and the sheer computational intensity of the simulation, the researchers relied on the computational power of the TeraGrid, employing systems at SDSC and NCSA.

  13. Social and Behavioral Science Gateway Understanding neural, cognitive, and social behaviors can depend on the ability to uncover coherent patterns among disparate data collected at different times and places. Researchers correlate subjects’ videotaped reactions with eye movements, heart rates, electroencephalogram results, and answers to written surveys.“It’s complicated,” says Chicago psychologist Bennett Bertenthal, and technological infrastructure has not kept pace with research needs.Bertenthal and his team are working to develop a set of cybertools to help collect and analyze behavioral data, collaborating with the TeraGrid Science Gateways Program. With NSF support, the Social Informatics Data (SID) Grid is a vast and sophisticated warehouse of readings and measurements meant to foster collaboration and to spur the development of standards for gathering and coding data—“which,” Bertenthal says, “right now is not part of the landscape.” In two years, when the SID Grid is complete, psychologists, sociologists, anthropologists, economists, and neuroscientists can share notes across the globe and use software interfaces like the ones shown above to synthesize numerous forms of streaming data at once.
