June 2007

For the fourth straight time, the BlueGene/L System development by IBM and DOE’s National Nuclear Security Administration (NNSA) and installed at DOE’s Lawrence Livermore National Laboratory in Livermore, Calif., claimed the No. 1 spot. The BlueGene/L reached a Linpack benchmark performance of 280.6 TFlop/s (“teraflops” or trillions of calculations per second). Two other systems exceeded the level of 100 TFlop/s: the upgraded Cray XT4/XT3 at DOE’s Oak Ridge National Laboratory, ranked No. 2 with a benchmark performance of 101.7 TFlop/s; and Sandia National Laboratory’s Cray Red Storm system, which ranked third at 101.4 TFlop/s.

Two new IBM BlueGene/L systems entered the Top 10, at the New York Center for Computational Science in Stony Brook, NY, (ranked No. 5) and at the Computational Center for Nanotechnology Innovations at Rensselaer Polytechnic Institute in Troy, NY, (ranked No. 7). These two systems represent the largest supercomputing installations in an academic setting. Also new to the Top 10 is a Dell system at the National Center for Supercomputing Applications, ranked No. 8.

The fastest supercomputer in Europe is an IBM JS21 cluster at the Barcelona Supercomputing Center in Spain, which ranked No. 9 at 62.63 TFlop/s. Rounding out the Top 10 is a new SGI system installed at the Leibniz Computer Center in Munich, Germany, with performance of 56.52. TFlop/s.

The highest ranked Japanese system is located at the Tokyo Institute of Technology and ranks No. 14 on the list. This system is a cluster integrated by NEC based on Sun Fire x4600 with Opteron processors, ClearSpeed accelerators and an InfiniBand interconnect.

More information about this TOP500 release can be found in the press release and related news. Additionally the highlights page provides an overview of changes since the last TOP500 release.
