Super computers ratings

1. DOE's IBM BlueGene/L system, installed at DOE’s Lawrence Livermore National Laboratory (LLNL). It has doubled in size (again) and has now achieved a record Linpack performance of 280.6 TFlop/s. It is still the only system ever to exceed the 100 TFlop/s mark.
2. IBM eServer Blue Gene Solution system, installed at IBM’s Thomas Watson Research Center with 91.20 TFlop/s Linpack performance.
3. ASCI Purple system at LLNL, also built by IBM , but based on the pSeries 575 servers. It reached 63.4 TFlop/s.
4. The Columbia system at NASA/Ames built by SGI slipped to the No. 4 spot, with a still equally impressive 51.87 TFlop/s.
5. DOE’s Sandia National Laboratories occupy. A new PowerEdge-based Dell system outperformed the enlarged ASCI Red Storm system by a narrow margin with 36.10 Tflops/s..
6. DOE’s Sandia National Laboratories. A new PowerEdge-based Dell system outperformed the enlarged ASCI Red Storm system by a narrow margin35.86 Tflop/s
7. The Earth Simulator, built by NEC
8. Cray XT3 system at DOE’s Oak Ridge National Laboratory with 20.53 Tflop/s.
