Despite the Jaguar nipping at its heels, Roadrunner continues to speed past the supercomputing pack. That's according to the twice yearly Top500 list of the fastest supercomputers in the world, which is to be announced Tuesday (June 23) at the 2009 International Supercomputing Conference in Hamburg, Germany. The list is released in June and November every year.

The IBM supercomputer housed at the U.S. Department of Energy's Los Alamos National Laboratory, known as Roadrunner, maintains the lead it grabbed a year ago. The computer can process 1.105 petaflop/s, or quadrillions of floating point operations per second, according to the Top500 Linpack benchmark. Hot on its heels for the second year in a row is the Cray XT5 Jaguar system at the DOE's Oak Ridge National Laboratory, which clocked in at 1.059 petaflop/s.

Here is the list of Top 10 supercomputers, with their manufacturers, location, and processing power:

  • Roadrunner, IBM, Los Alamos National Laboratory (1.105 petaflop/s)
  • Jaguar, Cray, Oak Ridge National Laboratory (1.059 petaflop/s)
  • JUGENE, IBM, Forschungszentrum Juelich (825.5 teraflop/s)
  • Pleiades, SGI, NASA Ames Research Center (487.01 teraflop/s)
  • BlueGeneL, IBM, Lawrence Livermore National Laboratory (478.2 teraflop/s)
  • Kraken XT5, Cray, National Institute for Computational Sciences (463.3 teraflop/s)
  • BlueGene/P, IBM, Argonne National Laboratory (458.61 teraflop/s)
  • Ranger, Sun, Texas Advanced Computing Center (433.20 teraflop/s)
  • Dawn, IBM, Lawrence Livermore National Laboratory (415.70 teraflop/s)
  • JUROPA, Bull SA, Forschungszentrum Juelich (274.80 teraflop/s
