Science Gateways -- A Paradigm Shift from Traditional High Performance 
  Computing
  
  Many new users will join the TeraGrid through a growing set of 
  TeraGrid science gateways that use web services and grid technologies 
  to provide access to TeraGrid resources through familiar web portal 
  and even desktop application interfaces. These gateways will enable 
  large numbers of researchers and educators with common types of 
  scientific problems to use the TeraGrid in ways tailored to the unique 
  requirements of their communities.
  
  "This is one of the most exciting things we are doing, and I believe 
  this kind of work will vastly increase the number of people able to 
  take advantage of these high performance computing resources," Catlett 
  said. "The TeraGrid is about enabling science by advancing and 
  evolving the underlying cyberinfrastructure. Today TeraGrid has about 
  a thousand users. Science gateways will grow that number to what we 
  hope will be in the 7,000 to 10,000 range."
  
  "So far we have partners developing TeraGrid science gateways to 
  support research and education in a variety of disciplines, including 
  atmospheric sciences, astronomy, life sciences, high-energy physics 
  and nanotechnology," Catlett said. "Some gateways are specialized for 
  projects centered on major scientific instruments, like Oak Ridge's 
  Spallation Neutron Source, while others are optimized for 
  environmental modelers and emergency response planning."
  
  
  Science on the TeraGrid
  
  TeraGrid enables researchers to analyze terabytes of data collected by 
  scientific instruments, telescopes, satellites and remote sensors. 
  They can manipulate and visualize enormous data sets in novel ways, 
  gaining new insights into research questions in basic science that are 
  of fundamental importance to society:
  
  
  
  Blood Flow Model: Even the extraordinarily accurate model of blood 
  flow in the human arterial system is so large that it depends on the 
  resources at four TeraGrid sites simultaneously: TACC, the Pittsburgh 
  Supercomputing Center, the National Center for Supercomputing 
  Applications in Illinois, and the San Diego Supercomputer Center. 
  Using software technology from the Globus Alliance, with specialized 
  tools developed at Northern Illinois University to manage the 
  communication between computers, Karniadakis is able to spread his 
  application across multiple computers. The total capacity of all the 
  computers used is nearly 35 teraflops. 
  
  "We take advantage of all of that," said Karniadakis, "and the fast 
  network connections make it possible to synchronize and re-synchronize 
  the calculations as necessary. Now we can investigate what happens 
  when arterial flow is blocked at any point, as may happen in various 
  disease processes, and we can design strategies to prevent or overcome 
  the effects."
