The Six-Core AMD Opteron processor-based system “Jaguar” is the world’s supreme supercomputer according to the TOP500 Organization, which today released its bi-annual list of the highest performing systems in the world. This mission-critical Cray XT5 system at Oak Ridge National Laboratory (ORNL) was recently upgraded from quad- to Six-Core AMD Opteron processors and delivers 2.3 petaflop/s theoretical peak performance and 1.75 petaflop/s performance on the Linpack benchmark.

“Supercomputer modeling and simulation is changing the face of science and sharpening America’s competitive edge,” said US Secretary of Energy Dr. Steven Chu.  “Oak Ridge and other DOE national laboratories are helping address major energy and climate challenges and lead America toward a clean energy future.”
