Oak Ridge supercomputer is the world's fastest for science
Date:11/17/2008

inning as a 26-teraflop system in 2005, Oak Ridge embarked upon a three-year series of aggressive upgrades designed to make their machine the world's most powerful computing system. The Cray XT was upgraded to 119 teraflops in 2006 and 263 teraflops in 2007. In 2008, with approximately 182,000 AMD Opteron processing cores, the new 1.64-petaflop system is more than 60 times larger than its original predecessor.

Thomas Zacharia, the laboratory's associate director for Computing and Computational Sciences, says petascale machines like Jaguar help advance critical scientific application areas by enabling researchers to get answers faster and explore complex, dynamic systems. In a matter of few days, Jaguar has already run scientific applications ranging from materials to combustion on the entire system, sustaining petaflops performance on multiple applications. A calculation that once took months can now be done in minutes. A 2008 report from the DOE Office of Science, America's largest funder of basic physical science programs at universities and government laboratories, said six of the top ten recent scientific advancements in computational science used Jaguar to provide unprecedented insight into supernovas, combustion, fusion, superconductivity, dark matter, and mathematics.

The DOE's Office of Science makes Jaguar available to scientists in academia, industry, and government to tackle the world's most complicated projects. Through the agency's Innovative and Novel Computational Impact on Theory and Experiment program, which allocates the supercomputer's resources through a peer-reviewed proposal system, researchers were allocated more than 140 million processor hours to 30 projects.

To date the computer simulations on Jaguar have focused largely on addressing new forms of energy and understanding the impact on climate resulting from energy use. For example, INCITE projects have simulated enzymatic breakdown of cellulose to make production
