November 2006

On the new list, the IBM BlueGene/L system, installed at DOE’s Lawrence Livermore National Laboratory (LLNL), retains the No. 1 spot with a Linpack performance of 280.6 teraflops (trillions of calculations per second, or Tflop/s).

The new No. 2 systems is Sandia National Laboratories’ Cray Red Storm supercomputer, only the second system ever to be recorded to exceed the 100 Tflops/s mark with 101.4 Tflops/s. The initial Red Storm system was ranked No. 9 in the last listing.

Slipping to No. 3 from No. 2 last June is the IBM eServer Blue Gene Solution system, installed at IBM’s Thomas Watson Research Center with 91.20 Tflops/s Linpack performance.

The new No. 5 is the largest system in Europe, an IBM JS21 cluster installed at the Barcelona Supercomputing Center. The system reached 62.63 Tflops/s.

Sandia’s Dell PowerEdge system was re-measured at 53 Tflops/s and was able to hold on to No. 6 spot.

The NovaScale 5160 system built by the French company Bull and installed at France’s Commissariat a l'Energie Atomique (CEA) slipped to No. 7, despite a new Linpack measurement of 52.84 Tflops/s. The original system debuted in the No. 5 position in June.

No. 9 is now occupied by the largest system in Japan, a cluster integrated by NEC based on Sun Fire X4600 with Opteron processors, ClearSpeed accelerators, and an InfiniBand interconnect. The system is installed at the Tokyo Institute of Technology.

The current No. 10 system is the upgraded Cray XT3 system at DOE’s Oak Ridge National Laboratory with 43.48 Tflop/s. It would have been ranked at No. 5 in June, and one year ago its predecessor was also No. 10 with just 20.53 Tflop/s.

The Earth Simulator, built by NEC, which held the No. 1 spot for five lists, has now slipped out of the TOP10 and is ranked at No 14.
