A supercomputer uses the same components as a home computer, simply uses more of them.
Computer parts times ten lulz.
Airplanes not necessarily use supercomputers but, supercomputers are used to design airplanes. One of the many uses of supercomputers is to model how wind and turbulence affect an airplane. Supercomputers are also used in advanced flight simulators.
That depends on the supercomputer.
Usually a customized version of Linux.
Most typically, supercomputers need dedicated air conditioning. The average computer can be cooled by air alone that is moved over the hot components by a fan. Supercomputers have hundreds or thousands of times as many powerful components packed in close proximity and working hard (often for days or weeks at a time) and there is simply no way to fan cool them effectively. Virtually all supercomputers are housed in dedicated buildings that have round-the-clock air conditioning.
Blue gene technology is a type of project designed to construct several supercomputers running in speeds of PFLOPS (petaFLOPS) range and at nearly 500 TFLOPS (teraFLOPS). It is used in supercomputers.
There are supercomputers in Pakistan. There are some in educational institutes like NUST, there are also supercomputers present within Atomic Energy and related research institutes. Throughout the nuclear history of Pakistan, we have been using supercomputers. Also, oil and gas and geological survey companies have also been using these supercomputers. Now the supercomputer of yesteryears is less powerful than alot of desktop computers of today. I guess with the advent of parallel processing, anyone can build with supercomputers.
to run a server for games and chat and the internet
Today supercomputers are the fastest computers available and are used by military and defense research agencies, universities, independent research centers and some engineering corporations. Major vendors of these computers include IBM and HP.
This may be referring to a "supercomputer" which is composed of many of the parts that a normal computer might have, but far far more of them. There are many custom-designed components in some supercomputers, so many of them are more than just a "bunch of regular computers hooked together." Supercomputers are usually very large, need special staff and technicians to maintain them and are used for advanced applications that would take normal computers many years to perform.
They are fast.
