Chinese supercomputer Tianhe-2 – the fastest in the world


Since the first mention of the Chinese supercomputer Tianhe-2 (“Galaxy 2”) was only a week. As expected , the solution of the Middle Kingdom is now headed the list of the fastest supercomputers in the world, moving from the pedestal to hold the palm of “Titan” ( Titan) .

The supercomputer Tianhe-2 was put into operation two years earlier than planned. It is built on a 12-core Intel Xeon Phi E5-2692, operating at a frequency of 2.2 GHz. The total number of cores of 3.12 million shares. Memory capacity is 1024 terabytes that 12,500 more compared to conventional PCs.

According to the results of benchmark Linpack, performance supercomputer Tianhe-2 is 33,862.7 teraflops, against 17 590 teraflops at Titan (Cray XK7). The theoretical peak performance of Tianhe-2 reaches 54 902.4 teraflops.

For statistics: Sequoia, full of IBM and based on the architecture-based BlueGene / Q, was the first supercomputer, which received more than 1 million processor cores (1,572,864 shares) and 17 with a score of 173.2 teraflops (Linpack) currently holds the third position the updated list of TOP500 supercomputers in the world.

The supercomputer Tianhe-2 is running an operating system Kylin Linux and is in defense science and technology university People’s Liberation Army of China.

One of the main indicators of a supercomputer is also the power consumption – 17,808 kW.

It should also be noted that the Tianhe-2 is the successor to the supercomputer Tianhe-1A, which was headed by TOP500 list in 2010, and now takes pride of place 10. For comparison, its peak performance is 2,566 teraflops.
