The country in similar position last three years ago.
The fastest computer - Titan in Tennessee oak ridge national laboratory - is jaguar upgrades, this system was held in 2009 the best head.
This supercomputer will be used to help develop more energy-efficient vehicles, model climate change and research on biological fuel engine.
Can also rent to a third party, the part of the operation, the United States department of energy energy company's research laboratory network.
The super computer fortune 500 list published in computer science professor's Hans's, in mannheim, the development of the situation since 1986 has remained. It was published in Salt Lake City, Utah, in SC12 supercomputing assembly.
Mixed processor
Titan before every beyond the champion of the IBM's sequoia - this is used for simulation, to help prolong life of nuclear weapons - because of its central processing unit (CPU) and graphics processing unit (GPU) technology of mixed.
According to the Linpack benchmark test, it run in 17.59 quadrillion times per second per second - equivalent to 17.59 quadrillion times calculation.
GPU processor design of hundreds of parallel computing
Reference measuring the performance of the real world - but in theory equipment can be increased to more than 20 quadrillion times/SEC "maximum performance".
In order to achieve this goal equipment has installed 18688 tesla K20x by GPU NVIDIA ? (British weida ?) work together, its existing CPU module.
The traditional super computer only to the dependence of CPU.
CPU core design for single a set of instructions, time, makes them is very suitable for task answer is used to work next calculation.
GPU core separate calculation will usually be slow, but can at the same time to make up for. This makes them the most suitable for "parallellisable work" - can be decomposed into several parts, and then at the same time the process of operation.
Mixed CPU and GPU together make the most suitable core in each process. Nvidia said, in most cases, now the GPU (graphics processor) about 90% of the workload of Titan.
"Based on Titan's Tesla GPU's oak ridge running in scale amazing complex applications, and verify the use of" accelerating operation ", in order to solve the urgent matter of science, said: "NVIDIA ? (British weida ?) GPU acceleration calculation business chief technical officer Steve Scott,.
Other top system includes:
Fujitsu K computer in kobe's physical &chemical research institute advanced computing science institute, Japan, this is the third point.
IBM's BlueGene/Q Myra computer in near Chicago argonne national library, in the United States, ranked fourth.
Another IBM blue gene/Q system, known as the Juqueen, in Forschungszentrum in Germany YuLiXi - Europe the fastest - this is the fifth out.
Out of the first 500 computer, use 62 CPU and GPU processor combination. Six months ago, this figure is 58.
