Scientists from the San Diego Supercomputer Center (SDSC) and other parts of the University of California, San Diego - conducting research in computer science, climate, biology, physics, engineering, and earthquake sciences - were awarded supercomputing processor time by the U.S. Department of Energy (DOE) as part of its 2010 Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program.
In total, the DOE's Office of Science awarded a record 1.6 billion processor hours to 69 new and renewed scientific projects. This marks the largest amount of supercomputing time ever allocated in the department's history, and an approximately 80 percent increase in processor hours from last year. Processor hours refer to allocations of time on a supercomputer.
New and renewed projects involving UC San Diego and SDSC researchers who were awarded processing time under the latest INCITE awards include:

Now in its seventh year, INCITE supports computationally intensive scientific investigations, allowing researchers at national laboratories, universities, and throughout industry to explore a wide range of scientific challenges. By providing scientists access to some of the world's most powerful supercomputers, these awards assist researchers in conducting their studies in weeks or months, as opposed to years or decades. A project receiving one million hours could run on 10,000 processors for 100 hours, or just over four days. Running a one-million-hour project on a dual-processor desktop computer would take more than 57 years, according to the DOE.
"Computation and supercomputing are critical to solving some of our greatest scientific challenges," said DOE Secretary Steven Chu. "This year's INCITE awards reflect the enormous growth in demand for complex modeling and simulation capabilities, which are essential to improving our economic prosperity and global competitiveness."
DOE's Office of Science is the single largest supporter of basic research in the physical sciences for the nation and ensures U.S. leadership across a broad range of scientific disciplines. For more information about the Office of Science, visit:
