What Is SuperComputer...???

A supercomputer is a computer at the frontline of current processing capacity, particularly speed of calculation.
Supercomputers are used for highly calculation-intensive tasks such as problems including quantum physics, weather forecasting, climate research, molecular modeling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physical simulations (such as simulation of airplanes in wind tunnels, simulation of the detonation of nuclear weapons, and research into nuclear fusion).

Today, supercomputers are typically one-of-a-kind custom designs produced by traditional companies such as Cray, IBM and Hewlett-Packard, who had purchased many of the 1980s companies to gain their experience. Currently, Japan's K computer, built by Fujitsu in Kobe, Japan is the fastest in the world.[2] It is three times faster than previous one to hold that title, the Tianhe-1A supercomputer located in China.
The term supercomputer itself is rather fluid, and the speed of earlier "supercomputers" tends to become typical of future ordinary computers. CDC's early machines were simply very fast scalar processors, some ten times the speed of the fastest machines offered by other companies. In the 1970s most supercomputers were dedicated to running a vector processor, and many of the newer players developed their own such processors at a lower price to enter the market. The early and mid-1980s saw machines with a modest number of vector processors working in parallel to become the standard. Typical numbers of processors were in the range of four to sixteen. In the later 1980s and 1990s, attention turned from vector processors to massive parallel processing systems with thousands of "ordinary" CPUs, some being off the shelf units and others being custom designs. Today, parallel designs are based on "off the shelf" server-class microprocessors, such as the PowerPC, Opteron, or Xeon, and coprocessors like NVIDIA Tesla GPGPUs, AMD GPUs, IBM Cell, FPGAs. Most[which?] modern supercomputers are now highly-tuned computer clusters using commodity processors combined with custom interconnects.
Relevant here is the distinction between capability computing and capacity computing, as defined by Graham et al. Capability computing is typically thought of as using the maximum computing power to solve a large problem in the shortest amount of time. Often a capability system is able to solve a problem of a size or complexity that no other computer can. Capacity computing in contrast is typically thought of as using efficient cost-effective computing power to solve somewhat large problems or many small problems or to prepare for a run on a capability system.

New Adventure.....

Hai..dh lme x update blog...hahahah....actually mlas sbenarnye...tu jer....yela...xde pape citer nk share...cme...citer yg ngarut2 byk arghh... ^_^....hurm....i wanna to tell something la..story...sket2 jer...nie hah...ade la....a person..tu...kan3.....die nie...hishhh malas la nk citer kn..buat panazzz hati jerr....alaaaaa....perlu ker nk tayang2 ko pnye " MAKWE" tu depan aq...hah....ishhh sewel pnye bdak...taw la dh ade "AWEK" kn....x yah ar...nk nunjuk2....isshhh bengangg jer aq... bak kate Sir Zul... A.A.K ( ADE AKU KESAH)...ker...hah.....bile duk ngan awek die..nk pndang2 aq...ape kes..nk sruh la aq tgk korg tgh bahagia yg teramat sgt tu...elehh...wa xda heran langsung la bro....setakat lu..tu....huh...puiihhhh....^^^....setakat nk buat dosa..buat maksiat nk wat ape...adoii3......DOSA2....hurm...setakat ni je la...sy nk ckp..mls nk citer pnjang2..nnt kan bertambah sy pnye dosa..plak..ok...see..ya... ^^^^ pyonggg.....~~~
