New Delhi: A supercomputer at US goverment’s Oak Ridge National Laboratory has become the world’s fastest computer. According to Top500 supercomputer ranking, the Cray XK7, Titan achieved a sustained computing capability of 17.5 petaflops - or 17.5 million billion mathematical calculations per second – on Linpack`s benchmark scale. Titan will be used for research on energy sources, climate change, efficient engines, materials and other scientific research, said the Oak Ridge National Laboratory. The supercomputer cost $200 million and is powered by 18,688 Nvidia Tesla K20X GPUs and over 560,640 AMD processors. The world`s top five fastest computers are as follows: 1. Titan Cray XK47 at Oak Ridge National Laboratory (17.59 petaflops/s) 2. Sequoia BlueGene/Q at Lawrence Livermore National Laboratory (16.33 petaflops/s) 3. Fujitsu’s K computer at the RIKEN Advanced Institute for Computational Science in Kobe, Japan (10.51 petaflops/s) 4. The Mira BlueGene/Q computer at Argonne National Laboratory in Lemont, Ill. (8.16 petaflops/s) 5. The JUQUEEN BlueGene/Q computer at the Forschungszentrum Juelich in Germany. (4.14 petaflops/s) (With Agencies inputs)
