ASCR-Funded Jaguar Heads the Top500
The Oak Ridge Leadership Computing Facility (OLCF) Cray XT5, known as Jaguar (figure 2), is the new number 1 supercomputer on the Top500 list. An upgrade from quad-core to six-core Opteron processors from Advanced Micro Devices (AMD) boosted Jaguar’s HPL performance to 1.76 petaflop/s. Jaguar, now with nearly a quarter of a million CPU cores, has a theoretical peak capability of 2.3 petaflop/s. The Linpack benchmark is used in determining the rankings of the Top500 list compiled by researchers at the University of Mannheim in Germany, the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL), and the University of Tennessee–Knoxville.

Figure 2. Jaguar’s Cray XT5 system ranks number 1 on the Top500 list. The XT4 system at Oak Ridge also made the top 20, coming in at number 16.
Other DOE systems in the top 20 include:
  • Number 2, Roadrunner, the IBM system at Los Alamos, 1.042 petaflop/s
  • Number 7, BlueGene/L at Lawrence Livermore, 478 teraflop/s
  • Number 8, BlueGene/P at Argonne, 459 teraflop/s
  • Number 10, Red Sky at Sandia, 424 teraflop/s
  • Number 11, Dawn, a BlueGene/P system at Lawrence Livermore, 416 teraflop/s
  • Number 15, Franklin, a Cray XT4 at NERSC, 266 teraflop/s
  • Number 16, the Jaguar Cray XT4 system at Oak Ridge, 205 teraflop/s
  • Number 17, Red Storm, a Cray XT3–XT4 system at Sandia, 204 teraflop/s
