The lead position on ORNLs Top 500 Supercomputer list is now Crays XT5 Jaguar supercomputer, besting IBMs Roadrunner.
The XT5 Jaguar, located at Oak Ridge National Lab in Tennessee, recently received a refresh that included upgrading its quad-core CPUs to hex-core Opteron processors. That means a 2.3 petaflop per second theoretical performance peak (nearly a quarter of a million cores), and 1.75 petaflops measured by the Linpack benchmark.
