The Chinese supercomputer called Tiahne-2 is today considered the fastest machine in the world, almost double the previous speed record with a performance of 33.86 petaflops. The appearance of Tiahne-2 on radar was noted long before its launch, and not so long ago he topped the list of five hundred supercomputers on our planet. What about other supercomputers?
Tiahne-2 was developed at the National University of Defense Technology of China and will work before the end of this year.
“The unexpected appearance of Tiahne-2, two years ahead of schedule, marks the return of China to the first position since November 2010, when Tiahne-1A was first on the list. The Tiahne-2 contains 16,000 nodes, each with two Intel Xeon Ivy Bridge processors in combination with three Xeon Phi processors. In total, 3,120,000 computing cores. ”
The combined performance of the 500 systems listed is 223 petaflops. Six months ago, this list produced 162 petaflops. A petaflop is one quadrillion floating point operations per second, or a million billion.
26 systems work at least with petaflop performance. IBM's Blue Gene / Q ranks four of the top ten, while Intel produces processors for 80.4% of all 500 systems. 39 systems use Nvidia GPU to speed up calculations, another 15 use accelerators or other near-processor technologies like ATI Radeon and Xeon Phi.
252 of 500 computers are installed in the USA, 112 in Europe, 66 in China and 30 in Japan. The slowest computer on the list runs at 96.6 teraflops. In the list last November, the slowest computer worked at a speed of 76.5 teraflops.
In addition to Tiahne-2, the only newcomer in the top ten is the Blue Gene / Q system, which is called the “Volcano” at the Livermore National Laboratory. Let's take a look at the top ten.
10: Tianhe-1A, National Supercomputing Center in China
9: SuperMUC, Leibniz Supercomputing Center in Germany
Using IBM iDataPlex servers, 300 terabytes of RAM and InfiniBand connections, 147,456 SuperMUC cores achieve a performance of 2.9 petaflops. Energy costs are reduced due to direct cooling of chips and memory with water.
8: Vulcan, Lawrence Livermore National Laboratory
This 4,3-petaflop system is based on IBM’s Blue Gene / Q supercomputer technology and is equipped with 393,216 cores. Not so long ago, in addition to government needs, "Volcano" also engaged in industrial, and also became available to research institutes.
7: Juqueen, Jülich Supercomputing Center in Germany
Another Blue Gene / Q system, Juqueen with 458,752 cores, reaches a speed of 5 petaflops. Using 2,301 kilowatts of energy, Juqueen was considered the most energy efficient supercomputer in November last year.
6: Stampede, Texas Advanced Computing Center at the University of Texas
With Dell PowerEdge servers equipped with Xeon processors and interconnected by InfiniBand, Stampede develops 5.2 petaflops. This is one of the largest systems available for open scientific research - any scientist from the US Institute may request to use some computer power.
5: Mira, Argonne National Laboratory, Department of Energy
This Blue Gene / Q system uses 786,432 cores to achieve 8.6 petaflops. In 2014, Mira will work at full capacity and will provide more than 5 billion computing hours per year to scientists (given the time for each core separately).
4: K computer, RIKEN Advanced Institute for Computational Science in Japan
In 2011, K computer was in first place on the list, and Fujitsu was involved in its creation. Delivering 10.5 petaflops at the expense of 705,024 Sparc cores, the K computer uses a six-dimensional toroidal joint called Tofu.
3: Sequoia, Lawrence Livermore National Laboratory
This computer was in first place in June 2012. Sequoia is used by the National Nuclear Security Administration to conduct simulations aimed at extending the life of a nuclear weapon. The Blue Gene / Q system has about 1.6 million cores and provides a performance of 17.2 petaflops.
2: Titan, Oak Ridge National Laboratory
Last November, this monster was first on the list and reproduced 17.6 petaflops. The system uses Cray processors based on AMD chips and Nvidia GPUs in 560,640 cores. Titan consumes 8,209 kilowatts of energy, for which he received the title of the most energy-efficient supercomputer last November.
1: Tianhe-2, National University of Defense Technology in China
Continuing the Tiahne-1A, the new world leader broke the speed record with a productivity of 33.86 petaflops. Tiahne-2 uses Intel Xeon based on Ivy Bridge and Xeon Phi with a total of 3.12 million cores. This computer consumes 17,808 kilowatts of energy and theoretically can accelerate to 54.9 petaflops. By the way, recently the oldest petaflop computer retired. Dear young.
Well, which of these computers will you install at home?
