Chinese Tianhe-2 supercomputer topped the Top500 world ranking

One of the Tianhe-2 computing nodes
Tianhe-2 is based on Intel Xeon processors. The computer consists of 16,000 nodes, each of which contains two Xeon IvyBridge processors and three Xeon Phi processors. In total, it has 3,120,000 computing cores and 1.4 petabytes of RAM. The supercomputer is running Kylin Linux. Communication between the nodes is carried out using a specially developed proprietary network TH Express-2, the heart of which is thirteen 576-port switches based on ASIC-chips made using 90nm technology, each of which has a throughput of 2.56 terabits per second.

Fragment of the Tianhe-2 Network Infrastructure
File storage has a capacity of 12.4 petabytes. Power consumption - 17.8 megawatts (24 megawatts including refrigeration and air conditioning). The computer covers an area of 720 m 2. The most detailed description of the Tianhe-2 supercomputer is in a report ( PDF ) by Jack Dongarr from the Oak Ridge National Laboratory.
