We all know about supercomputer which can process trillions of data in a second. At present the world fastest supercomputer is Tianhe-2 which had made in china. It is the next series of Tianhe-1 supercomputer. In 2010, Tianhe-1 was the world’s fastest supercomputer. The list of fastest 10 supercomputer’s in the world is given below:
The development of Tianhe-2 was sponsored by the 863 High Technology Program of the Chinese Government, the government of Guangdong province, and the government of Guangzhou city. With the cooperation of the Chinese technology company Inspur, China’s National University of Defense Technology (NUDT) had built this supercomputer.
At first, Titan supercomputer which is situated in the U.S. Department of Energy’s Oak Ridge National Laboratory was the fastest supercomputer. But Tianhe-2 beat Titan in a ratio of 2:1 according to speed. Tianhe-2 achieved 33.86 petaflops of speed where Titan achieved only 17.59 petalops of speed. In computing, FLOPS (FLoating-point Operations Per Second) is a measure of computer performance, especially in fields of scientific calculations that make heavy use of floating-point calculations, similar to the older, simpler, instructions per second. We also can say that Petaflop is a measure of a computer’s processing speed and can be expressed as a thousand trillion floating point operation per second. Flops are floating-point operations per second. Floating-point is considered to be a method of encoding real numbers within the limits of finite precision available on computers.
Tianhe-2 consists of 16,000 compute nodes, each comprising two Intel Ivy Bridge Xeon processors and three Xeon Phi chips for a total of 3,120,000 cores. This figure represents the world’s biggest installation of Ivy Bridge and Xeon Phi chips. Each of the 16,000 nodes has 88 gigabytes of memory for the Ivy Bridge part and 8 gigabytes for the Xeon part. The system total is 1.404 petabytes of memory. The computer takes up 720 square meters of space.
The front-end system consists of 4096 Galaxy FT-1500 CPUs, a chip designed and built by NUDT. Each FT-1500 has 16 cores and has a 1.8 gigahertz cycle time. The chip has a performance of 144 gigaflops and runs at 65 watts. The interconnect, called the TH Express-2, was designed in house by NUDT. It uses a fat tree topology with 13 switches each of 576 ports.
Tianhe-2 runs on Kylin Linux, a version of the operating system developed by NUDT. Resource management is based on Simple Linux Utility for Resource Management (SLURM).
