What Is Supercomputer?

Recommended Posts

I'll try my best to define this....A supercomputer is an extremely powerful computing system which is mostly used to process a lot of data in very little time. Frankly I never thought about what this "data" is, and what's the need for processing it so fast! Supercomputers can perform millions, billions or even trillions of operations in a second (based on their speed and power). And they're not exactly pretty to look at. A single supercomputer may fill up an entire room or even a building! If I'm not wrong, they are mostly used for research purposes and the common man doesn't have any real use with the supercomputer in his daily life....

Check out good old wikipedia for more info on supercomputers

They're generally hundreds or thousands of CPUs working in parallel to complete often repetitive or complex tasks and simulations. For example, that supercomputer has 420 quad-core processors, mostly running at 2.83GHz, with 2.5TB of RAM and 47TB of hard drive storage. And, of course, it runs Linux :)

@rvalkass, thanks for screen-shot. Which university is this by the way ?

 

@Topic, you can find more about supercomputer here. And if you want to know about quantum computing then this PDF will help. (To know from this PDF, you need to have some background about computing). Also to know about quantum algorithm you can find information in this paper.

I prefer to give a twisted answer for this question as I know that everyone else will give a scientific definition for it.Wonder if I call a computer which does superficial things a super computer. That is it does nothing but all rubbish that a bow intellectual IQ person will easily be able to perform.What if the computer does supernatural things like acting GOD and bringing goodness and prosperity to the needy. May be teleport you to the moon and back in a flash and you make a great outing for dinner in the moon. It acts as a UFO to the beings living some 3000 light years away and comes back after a days travel that far with some valuable information for NASA's secret mission to send Obama for excursion to outer space. Well Obama will of-course fund such projects as much as possible because after all this kind of projects are for his personal interest as well.

Lol no chance. Have you seen echelon conspiracy movie recently ?

The most super supercomputers are meant for calculating the meaning of life. This has been attempted before and I myself have learned the meaning of life from these calculations and you could know the answer to Life, The Universe, and Everything, as well. Unfortunately, you're not going to like it.

Did this come from the Hitchhikers Guide to the Galaxy? The answer to Life, The Universe, and Everything is 42.

Type this sentence in a Google search bar " the answer to life, the universe and everything " and hit enter. It's actually a Google hack.

A couple interesting tidbits gleaned by visiting the top500 site: The most powerful supercomputer in the world, outside of NSA, is a IBM using an advanced version of the same processor used in the Sony Playstation 3! The computer achieved a staggering 1.026 Petaflop/s speed and is being used by the Los Alamos National Laboratory in New Mexico. The 2nd fastest computer in the world is less than half as fast! One way to build your own supercomputer would be to find cooled racks like those pictured above and fill the racks with Apple servers. Each server can contain 2 quad-core Xeon "Nehelam" Intel processors, 3Gb (minimum) memory, 3 1Tb hard drives, dual 750W power supplies and much much more for about $7k each. Throw about 20 of those in a cabinet along with a few racks of RAID arrays and you've got yourself a supercomputer running at probably over 100 Teraflop/s. And if you order that many, Apple would probably be happy to give you a good discount and lots of support in return for good publicity.

According to game developers they are difficult to program to use effectively, but when you do they are lightning quick compared to pretty much anything else on the market, especially for simple and repetitive tasks like Folding@Home and general supercomputing tasks.

You don't really see many Apple supercomputers, if any at all, do you? I suppose the cost of hardware is higher with Apple, but if you're building a supercomputer and getting a bulk discount then that might not be an issue. I guess it's simply the fact that you're locked in to using Apple's OS, so they've never really got a foothold in a market dominated by Linux and Windows PCs.

Not at all. Apple OS IS built on UNIX. Check out the Server OS that comes with it...

 

This is about a year and a half old, but the pics alone are worth looking at... http://gizmodo.com/254251/apple-running-top-500-supercomputer-at-nab

 

 

And the OS?

Xserve isnt just for the Mac. With out-of-the-box support for Mac, Windows, UNIX, and Linux clients, Xserve is the easiest way to provide powerful, innovative network and Internet services for multiplatform workgroups. Active Directory support, for example, makes it easy to add Xserve to your Windows-based IT environment to support an expanding population of Mac clients.

A few years ago, Virginia Tech bought a G5 Apple supercomputer that, at the time, ranked #3 in the world and cost a fraction of what competitors would've charged. Here's the latest I could find on their computer, but it's a few years old now. http://forums.xisto.com/no_longer_exists/

Hi there. An important thing to note about supercomputers is that they're not necessarily a single computing system, but more often a network of computers in a distributed computing environment (there are many, many distributed computing solutions out there). With this in mind, and regarding your question, it can be difficult to imagine with a supercomputer "looks" like, as some supercomputing setups span great distances. There's a website (known as TOP500) that contains a list of the most powerful supercomputing setups known to be in operation. I didn't include the link, as I'm not sure if that's allowed on these forums, but a quick google search can find it for you.
