Supercomputers superior in speed than computers in ordinary houses by using innovative design shaped cabinets that make them able to perform multiple tasks in parallel, and also details to the civil complex. This computer is usually devoted to a particular computation, usually numerical computation, and it isn't good results in a common task.

Supercomputer Designed

Memories hierarchies are carefully designed to ensure the processor still receive data and instructions at any time; in fact, the difference in performance with a regular computer located in the memory hierarchy and its components. Its I/O System which is also designed to be able to support a wide bandwidth.
By the parallel system in general, Amdahl's law applies, and supercomputer designed to eliminate weaknesses series arrangement, and the use of parallel systems hardware to accelerate from weakness narrow bandwidth.
Supercomputers are used for calculation-intensive tasks such as; weather forecasting, climate research (including global warming research, molecular modeling, physical simulations (such as simulation of airplanes in wind tunnels, simulation of the detonation of nuclear weapons, and nuclear fusion research), script analysis, and so on others. the Military and the Science Agencies one of the main users of supercomputers.

"Tianhe-2" the China Supercomputer

Until this year, 'Tianhe-2' or in English called the 'Milky Way-2' is still listed as the most intelligent computer on earth. How imagine that this computer was build to take up to 1.300 Scientists and Engineers.
This Computer is belong to Chinese Government which is also made by a leading University in China that has the 'brain' or the number of CPU cores will make you surprised, amounted to 3.12 million cores. If it compare with a home computer that only has a maximum of 7 or 8 core only.
With 16,000 computer nodes, each composed of two Intel Ivy Bridge Xeon processors and three Xeon Phi coprocessor chips, the 'Tianhe-2' is almost twice as fast as the second computer on the list, that is the United States 'Cray Titan'. And while the US still has the most computers on the TOP500 list with 233, that number is 32 fewer than it had on the previous list. Meanwhile, China now has 76 computers on the list, 13 more than last time.

The Specs Components of "Tianhe-2"

One look at the specs and you can see why the Tianhe-2 is at the top of the list:

    Cores : 3,120,000
    Linpack Performance (Rmax) : 33,862.7 TFlop/s
    Theoretical Peak (Rpeak) : 54,902.4 TFlop/s
    Power : 17,808.00 kW
    Memory : 1,024,000 GB
    Interconnect : TH Express-2
    Operating System : Kylin Linux
    Compiler : icc
    Math Library : Intel MKL-11.0.0
    MPI : MPICH2 with a customized GLEX Channel

By a lot of the cores, the "Tianhe-2" is able to perform calculations of data up to 33 860 trillion times per second. Tech Radar reported that one hour calculation of Tianhe-2 is 1000 years predicted calculation performed by all the Chinese that exist today.
Besides, it is so powerful that it required a team of 1,300 scientists and engineers from China’s National University of Defense Technology to build that Superfast Computer. Sponsored by the "People’s Republic of China’s" with High-Tech Development Plan, this computer was built on the premise that China could one day become independent of financial obligations for foreign technologies.
The computer is so powerful, that it’s able to perform 33,860 trillion calculations per second. One hour of these calculations by the machine is the equivalent of 1,000 years of difficult sums by 1.3 billion people – ironically, the current population in China.

Variety of Strategic Purposes

Chinese Government funded project hopes when "Tianhe-2" supercomputer that can make the Bamboo Curtain country no longer dependent on foreign technology. According to the University Of Defense Technology Of China, "Tianhe-2" is used to develop cyber security applications owned by the Government of China.
However, many predict that China will use more of it. Given the current super computers in the world used for a variety of strategic purposes.
China’s growth in computer technology is impressive. While the 'Tianhe-2' is the only Chinese computer ranked in the top 10, the Asian nation now has nearly as many computers as the UK (30), France (27), and Germany (23) combined. And while there seems to be a slowing trend in performance growth from all nations, China is one of two nations (the other being Japan) which is growing. But, does this mean China could become the financially independent from foreign technologies? Not quite!
According to a press release issued by the TOP500, “Intel continues to provide the processors for the largest share (85.4 percent) of TOP500 systems.” Couple this with the fact that HP has the lead in systems with 182 (36 percent) and IBM is in second place with 176 (35 percent), and it becomes apparent that American companies are paving the future of computer technologies. However, because supercomputers have become so powerful, it has actually been a hindrance to the overall growth in computer system performance.

"Sequoia" the US Supercomputer

The "NNSA-National Nuclear Security Administration" (National Nuclear Security Administration of the Department of the United States) appoints Lawrence Livermore National Laboratory as a developer for two new super computers these are "Sequoia" and "Dawn", and IBM as a designer and builder of the supercomputer. This new technology allows for the simulation of weapons testing needs intelligently to avoid direct testing.
In cooperation agreement, said "Sequoia" will use future technology called IBM BlueGene Technology, with the ability to reach more than 20 petaflop (20 thousand trillion calculations per second), which is planned to be delivered in 2011 and distributed to operational in last 2012.
Here following the fourth of "Sequoia" prospective for the future technology in computer:

  • Sequoia will be a major step in the advancement of technology in computer calculation capabilities. With speeds reaching 20 petaflop sequoia will work 15 times faster than existing supercomputers in his time.
  • Sequoia will be used to ensure the safety and reliability of the nuclear weapons stockpile US national. It is also possible to be used to study astronomy, energy, human genome and climate change.
  • Sequoia will be based on the technology of the future IBM BlueGene technology that uses 1.6 million IBM POWER processors and 1.6 petabytes of memory, which is stored in a refrigerator-sized racks 3422 96 square meters. Sequoia will take advantage of the use of advanced optical fiber at all levels.
  • Sequoia will use the Linux Operating System.

"K Computer" Japanese Supercomputer

Three of the fastest supercomputers of the 500 fastest computers in the world in the last June 2011 are:

Based on the various references that in last November 2005, 61% of the 500 fastest supercomputers are in the United States followed by the United Kingdom (8.2%), Germany (4.8%), Japan (4.2%), the People's Republic of China (3.4%), Australia (2.2%), Israel (1.8%), France (1.6%), South Korea (1.4%), Italy (1.2%) and Canada (1.2%). 43.8% of the 500 fastest supercomputers are made by IBM, followed by Hewlett-Packard (33.8%), Cray (3.6%), SGI (3.6%), Dell (3.4%), Linux Network (3.2%), NEC (1.2%), Atipa Technology (1%), homemade (1%) and Hitachi (1%).
Finally, the giant Intel Processor still leads the world with the Intel IA-32 processors are used 41.2% of the 500 fastest supercomputers is followed by Intel EM64T (16.2%), Power (14.6%), AMD x86-64 (11%), Intel IA-64 (9.2%), PA-RISC (3.4%) and Cray (1.6%).

1)* FLOPS is an abbreviation of the term in English "Floating point Operations Per Second" which refers to the unit for the amount of computation can be performed by a computing device (in this case the computer) to fractions (floating point) per unit time. FLOPS is a unit of measurement of the speed of the performance of a microprocessor is usually in a scientific application (scientific applications), such as to calculate / simulate the movement data of the Earth in real time. For example, the Cray 1 supercomputer has the ability to perform calculations as many as 80 million calculations of the fractions in 1 second, and can be expressed in units of 80 MFLOPS/megaflops.
The Unit of FLOPS are following:
n = 15petaflops
Symbol= PFLOPS
Numerical= 10^15
Numerous Equivalent=

2)* ICT (Information Communication and Technology) is an important aspect of a process, includes two aspects in it, namely Technology Information and Communication Technology. Information technology is as described above. whereas communication technology is any technology that can help people to communicate with the each of others. So the Information and Communication Technology (ICT) is a combination of Information Technology and Communication Technology.
