This is Jaguar, the new King of the Petaputer Hill, running at 1.75 petaflops-per-second. The Cray XT5 supercomputer was behind IBM's Roadrunnner for more than a year, until some clever scientist decided to paint a running Jaguar all over it.
Then it surpassed IBM's 1.04 petaflop/s supercomputer, achieving its 1.74 quadrillion floating points operation according to the Top500 Linpack benchmark. I mean, it was probably some extra CPUs coming online, but I'm pretty sure the main reason for the boost was that drawing.
Roadrunner took a dip from June's 2009 test, which gave it 1.105 petaflops. That's probably Wile E. Coyote's fault. My recommendation to IBM: Paint flames on it to win the #1 spot back.
This is the current top ten:
1. Jaguar, Cray, Oak Ridge National Laboratory, USA (1.75 petaflop/s)
2. Roadrunner, IBM, Los Alamos National Laboratory, USA (1.04 petaflop/s)
3. Kraken XT5, Cray, National Institute for Computational Sciences, USA (832 teraflop/s)
4. JUGENE, IBM, Forschungszentrum Juelich, Germany (825.5 teraflop/s)
5. Tianhe-1, NUDT, National SuperComputer Center, Tianjin, China (563.1 teraflop/s)
6. Pleiades, SGI, NASA Ames Research Center, USA (544.3 teraflop/s)
7. BlueGeneL, IBM, Lawrence Livermore National Laboratory, USA (478.2 teraflop/s)
8. BlueGene/P, IBM, Argonne National Laboratory, USA (458.61 teraflop/s)
9. Ranger, Sun, Texas Advanced Computing Center, USA (433.20 teraflop/s)
10. Red Sky, Sun, Sandia National Laboratories, USA (423.9 teraflop/s)
