What would you have if you put over 7000 NVIDIA Tesla GPUs together? Chances are you would have the worlds fastest computer. Chinas National University of Defense Technology has put together 7,168 NVIDIA Tesla M2050 (Fermi) GPUs, 14,336 CPUs, 262TB of memory and 2PB of storage, giving them the worlds fastest super computer with a Linpack performance of 2.5 petaflops. Peak performance of the new Tianhe-1A super computer is 4.7 petaflops. Oh, did I mention it draws 4 Megawatts of power! The Tianhe-1A super computer means the Us has lost its top spot in the TOP500.
