Fastest supercomputer gets faster
Blue Gene/L, the fastest supercomputer in the world, has broken its own speed record, reaching 135.5 teraflops - a trillion calculations a second.
That is double the speed it clocked up to take it to the number one spot in the Top 500 supercomputer league.
The IBM Blue Gene machine that achieved the new mark is being assembled for the Lawrence Livermore National Laboratory, a US Department of Energy (DOE) lab.
It did 70.72 teraflops last year to beat Japan's NEC Earth Simulator.
The Blue Gene/L is due to be completed for the Livermore labs in 2005.
