Tianhe-I, Tianhe-1 or TH-1 (天河一号) (Mandarin pronunciation: [tʰjɛ́nxɤ̌ íxâʊ], pinyin: Tiānhé yīhào), in English, "Milky Way (literally, Sky River) Number One",[1] is a supercomputer capable of over 2½ quadrillion floating point operations per second (see FLOPS). Located at the National Supercomputing Center in Tianjin, China, it is one of the few petaFLOPS-level supercomputers in the world.[2][3]
In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.507 petaFLOPS.[4]
Both the original Tianhe-1 and Tianhe-1A use a Linux-based operating system.[5][6]
Background
Tianhe-1
Tianhe-1 was developed by the Chinese National University of Defense Technology (NUDT) in Changsha, Hunan. It was first revealed to the public on 29 October 2009, and was immediately ranked as the world's fifth fastest supercomputer in the TOP500 list released at the 2009 Supercomputing Conference (SC09) held in Portland, Oregon, on 16 November 2009. Tianhe achieved a speed of 563 teraflops in its first Top 500 test and had a peak performance of 1.2 petaflops. Thus at startup, the system had an efficiency of 46%.[7][8] Originally, Tianhe-1 was powered by 4,096 Intel Xeon E5540 processors and 1,024 Intel Xeon E5450 processors, with 5,120 AMD graphics processing units (GPUs), which were made up of 2,560 dual-GPU ATI Radeon HD 4870 X2 graphics cards.[9][10]
Tianhe-1A
In October 2010, Tianhe-1A, a separate supercomputer, was unveiled at HPC 2010 China.[11] It is now equipped with 14,336 Xeon X5670 processors and 7,168 Nvidia Tesla M2050 general purpose GPUs. 2,048 NUDT FT1000 heterogeneous processors are also installed in the system, but their computing power was not counted into the machine's official Linpack statistics as of October 2010.[12] Tianhe-1A has a theoretical peak performance of 4.701 petaflops.[13] NVIDIA suggests that it would have taken "50,000 CPUs and twice as much floor space to deliver the same performance using CPUs alone." The current heterogeneous system consumes 4.04 megawatts compared to over 12 megawatts had it been built only with CPUs.[14]
The Tianhe-1A system is composed of 112 compute cabinets, 12 storage cabinets, 6 communications cabinets, and 8 I/O cabinets. Each compute cabinet is composed of four frames, with each frame containing eight blades, plus a 16-port switching board. Each blade is composed of two compute nodes, with each compute node containing two Xeon X5670 6-core processors and one Nvidia M2050 GPU processor.[15] The system has 3584 total blades containing 7168 GPUs, and 14,336 CPUs. The total disk storage of the systems is 2 Petabytes implemented as a Lustre clustered file system,[1] and the total memory size of the system is 262 Terabytes.[12]
Another significant reason for the increased performance of the upgraded Tianhe-1A system is the Chinese-designed NUDT custom designed proprietary high-speed interconnect called Arch that runs at 160 Gbps, twice the bandwidth of InfiniBand.[12]
The supercomputer is installed at the National Supercomputing Center, Tianjin, and is used to carry out computations for petroleum exploration and aircraft simulation.[8] It is an "open access" computer meaning it provides services for other countries.[16]
