The No. 1 position was again claimed by the BlueGene/L System, a joint development of IBM and DOE's National Nuclear Security Administration (NNSA) and installed at DOE's Lawrence Livermore National Laboratory in Livermore, Calif. BlueGene/L also occupied the No. 1 position on the last two TOP500 lists. However, the system was doubled in size during the last six months and reached a new record Linpack benchmark performance of 280.6 TFlop/s ("teraflops" or trillions of calculations per second). No other system has yet exceeded the level of 100 TFlop/s and this system is expected to remain the No. 1 Supercomputer in the world for the next few editions of the TOP500 list.
The pace of innovation and performance improvements seen at the very high end of scientific computing shows no sign of slowing down. This time, four of the TOP10 systems on the June 2005 TOP500 list were displaced by newly installed systems, and the last 221 systems on the list from June 2005 are now too small to be included.
