Titan, the fastest supercomputer

40th edition of the Top500 has put Titan, the Cray system XK7, in the first place on the list of the fastest supercomputers in the world.

Using as many processor 560,640, including 261,632 K20x Nvidia accelerator cores, the performance achieved 17.59 petaflop / s (1000 trillion calculations per second) on the Linpack benchmark. Titan is now installed at Oak Ridge National Laboratory.

Titan managed to shift Sequoia Lawrence Livermore National Laboratory

belongs to the second position. Sequoia which is a system of IBM BlueGene / Q supercomputer became the fastest since June 1, 2012 with a performance of 16.32 petaflop / s. Sequoia is the first system that has more than one million cores, the cores 1,572,864.

Here are the top 10 fastest supercomputers according to the Top500, as in a press release yesterday.

      1. Titan, XK7 Cray system, the fastest supercomputer in the world.

      2. Sequoia systems, IBM BlueGene / Q.

      3. Fujitsu K computer belonging installed at the RIKEN Advanced Institute for Computational Science         (AICS) in Kobe, Japan. Its performance reaches 10.51 petaflop / s and using 705,024 cores SPARC64.

      4. Mira, the system BlueGene / Q, at Argonne National Laboratory, with a performance of 10.51 petaflop / s, using 705,024 cores SPARC64. Mira used by hundreds of companies, universities, and government agencies.

      5. JUQUEEN system, BlueGene / Q, at the Forschungszentrum Juelich, Germany, has been upgraded and is now the most powerful system in Europe. Using 155,000 cores, this supercomputer has a performance of 3 petaflop / s.

      6. Super MUC, installed at Leibniz Rechenzentrum, an IBM system with 147,456 cores Dataplex DX360M4. The processor used is Intel Xeon E5-268 8C 2.7 GHz and achieved performance of 2.897 petaflop / s.

      7. Stampede, the Dell PowerEdge C8220 systems, installed in the Texas Advanced Computing Center, University of Texas, Austin. The supercomputer uses Intel Xeon processors and achieved Phi's new 2.6 petaflop speed / s.

      8. Tianhe-A1 is installed at the National Supercomputing Center in Tianjin. Using 186,368 cores, performance reached 2.566 petaflop / s.

      9. Fermi systems, BlueGene / Q, using processor 1.60 GHz Power BQC 16C, 163,840 cores, performing 1.725 petaflop / s. This supercomputer is in Cineca, Italy.

      10. DARPA Trial Subset, system Power 775, POWER7 8C 3.836 GHz. With 63,360 cores, IBM's supercomputer performance reaches 1.515 petaflop / s.

Now there are 23 large-scale supercomputer that has a performance map (Petaflops / s). First supercomputer to achieve the performance of large-scale maps are Roadrunner, Cray Blue Waters system at NCSA, University of Illinois, which began operating four and a half years ago.
