Oak Ridge 'Jaguar' supercomputer is World's fastest
Date:11/16/2009

"The early petascale results indicate that Jaguar will continue to accelerate the Department of Energy's mission of breakthrough science," said Jeff Nichols, ORNL's associate laboratory director for computing and computational sciences. "With increased computational capability, the scientific research community is able to obtain results faster, understand better the complexities involved, and provide critical information to policy-makers."

Hack, a leading climate modeler, concurs. "The speed and power of petascale computing enables researchers to explore increased complexity in dynamic systems," he said. As an example he cited the world's first continuous simulation showing abrupt climate change, led by scientists at the University of Wisconsin and the National Center for Atmospheric Research. Run on Jaguar earlier this year, the computer's speed made it possible to publish the results by July in Science.

Through the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, DOE's leadership computing facilities at Oak Ridge and Argonne national laboratories will employ a competitive peer review process to allocate researchers 1.6 billion processor hours in 2010. In 2009 the Oak Ridge Leadership Computing Facility allocated 470 million processor hours on Jaguar through the INCITE program.

Scientists in industry, academia, and government have requested more than 2 billion processor hours on Jaguar for 2010. The six-core upgrade on Jaguar will enable Oak Ridge to allocate 1 billion processor hours. Equipped with unprecedented computer power, materials scientists can simulate superconducting materials and magnetic nanoparticles with greater realism. Climate scientists can improve accuracy, resolution, and complexity of Earth system models, and physicists can simulate quarks and explore masses, decays, and other properties of the fundamental constituents of matter.
