Highlights from the Top 10 - June 2007

All changes are from November 2006 to June 2007:

• While the No. 1 system is still unchallenged, the rest of the TOP10 experienced large changes since November 2006.
• The new and previous No. 1 is DOE's IBM BlueGene/L system, installed at DOE’s Lawrence Livermore National Laboratory (LLNL) with a Linpack performance of 280.6 TFlop/s.
• The upgraded Cray XT4/XT3 system at DOE’s Oak Ridge National Laboratory is the third system ever recorded to exceed the 100 TFlop/s mark. It is No2 with 101.7 Tflop/s.
• It ever so slightly edged out Sandia’s Cray Red Storm system, which holds the No. 3 spot with 101.4 TFlop/s.
• Two new BlueGene/L systems entered the TOP10. They are both located in the state of New York and represent the largest academic supercomputer installations.
• The No. 5 system is installed at Stony Brook, NY at the New York Center for Computational Science (NYCCS) http://www.sunysb.edu/nyccs/.
• The No. 7 system at the Rensselaer Polytechnic at the Computational Center for Nanotechnology Innovations (CCNI), Try, NY http://www.rpi.edu/research/ccni/.
• The new No.8 system was build by Dell and is installed at NCSA in Illinois. It was measured at 62.68 TFlop/s.
• Just behind on No. 9 is the largest system in Europe, an IBM JS21 cluster installed at the Barcelona Supercomputing Center, with performance of 62.63 TFlop/s. It held the No 5 spot just 6 month ago.
• The No. 10 was captured by a new SGI system installed in Germany at the Leibniz Computing Center in Munich. It was measured with 56.52 TFlop/s
• The first Japanese system is at No. 14. It is a cluster integrated by NEC based on Sun Fire X4600 with Opteron processors, ClearSpeed accelerators and an InfiniBand interconnect, installed at the Tokyo Institute of Technology.
