Supercomputers are defined to be the fastest line of computers. Contrary to mainframes and microcomputers, supercomputers are dedicated to execute only a few programs simultaneously. This is to avoid compromising the speed needed for tasks requiring a lot of processing speed. Among the functions of supercomputers are weather forecasting, high-end graphic animations, dynamic calculations, nuclear power researches, and fuel exploration.
The speed of supercomputers is measured in FLOPS (Floating Point Operations Per Second). Before, supercomputers are stuck to what is called “Petaflop Barrier” or A thousand teraflops. However, in June 2008, the “Petaflop Barrier” has been shredded by IBM’s Roadrunner installed at DOE’s Los Alamos National Laboratory (LANL). Today, there exists two supercomputers breaking the petaflop barrier.
Holding on to the No. 1 spot as the world fastest computer running in 1105.00 Teraflops is IBM’s Roadrunner found in Los Alamos National Laboratory, USA. Second place is the second teraflop barrier-breaker with a speed of 1059.00 Teraflops is Cray XT5 of Cray Research at Oak Ridge National Laboratory, USA. Third spot is running in 825.50 Teraflops called JUGENE of IBM located at Jülich Research Centre, Germany. Fourth place is Pleiades of SGI based in NASA/Ames Research Center, USA with a speed of 487.01 Teraflops. Fifth post is Blue Gene/L by IBM installed at Lawrence Livermore National Laboratory, USA running in 478.20 Teraflops. Sixth placer is called Kraken by Cray Research found in National Institute for Computational Sciences, USA with a speed of 463.30 Teraflops. Seventh place holder is IBM’s Intrepid running on 458.61 Teraflops at Argonne National Laboratory, USA. In eighth position is called Ranger by Sun Microsystems located in Texas Advanced Computing Center, USA with a speed of 433.20 Teraflops. IBM’s Dawn is in ninth place with its 415.70 Teraflops speed installed in Lawrence Livermore National Laboratory, USA. The top 10 supercomputer as of ISC09 conference on June 23, 2009 at Hamburg, Germany is called JUROPA by Groupe Bull located in Jülich Research Centre, Germany.

What’s the Right Desktop For You?
With so many desktop computers today, how do you know which is the right one for you? Choosing a desktop can be dizzying with the choices available. The different specs of each of these can give you a hard time deciding. With the advancement of computers today, a particular desktop might be outdated very quickly so you really need to determine the best features out of the options available.
What you need to do first is to decide what you need the computer for. It includes what you’re going to do with your desktop, whether you do games, watch movies, and so forth. To be safe, you should consider the desktops in mid-ranges when it comes to their specifications. You only need the powerful ones if you intend to use software that requires heavy specifications. You can perform a search first in the internet if you still don’t know what you want, there is a lot of information you can find there using the search engines we have. The common things you need to consider aside from the hardware and the specification of a certain desktop are the things like warranty, technical support, upgrades, and the quality of each component. A quality part such as the keyboard and mouse can make you comfortable even if you work for hours, so make sure you have those quality ones.
You also need to consider all the “extras”: examples are the DVD burner, more USB ports, and a webcam although they are not that necessary for your desktop, theycan still give easiness and enjoyment while you do your work. If you’re willing to pay extra amount then why not include them.
Before making a decision, list the entire brand you want for the components of your desktop and compare prices and quality with what’s available in the market. Do these and you will get the best value out of your budget, as well as a desktop just right for you which will give you comforts while working.

The Fastest Best-Selling Desktop Computer Processor Ever
This is really a jaw-dropping speed processor a computer can ever have. I am talking about the AMD’s Athlon X2 Dual-Core QL-64. It belongs to the AMD’s X2 multi-core processor family with an awesome CPU speed of 2.16 GHz. It is equipped with the 65nm AMD’s manufacturing technology but with a smaller wattage rate of 35 watts. It is definitely the fastest computer processor these days.
Athlon X2 Dual-Core QL-64 has two separate CPU cores on a single die. Each core is running on 2.16 GHz speed. The standard multiplier for determining the overall speed of a processor is 1.8. So when two cores are running together, Athlon X2 Dual-Core QL-64 can have an astounding speed of 1.8 X 2.16 = 3.88 GHz. You could barely feel any buffering or lagging even when you are running on different high-end multi-thread software applications all at the same time.
Athlon X2 Dual-Core QL-64 processor bus speed can also reach around 3600 MHz. Of course, the motherboard controls the bus speed so it must meet with the CPU’s bus speed for optimum performance. Bus speed is the rate at which computer processor can transfer or process information (with different computer parts like motherboard and RAM) per second. Typical bus speed for motherboard would be 4000 MHz and RAM capacity of 4 GB.
Athlon X2 Dual-Core QL-64 has a shared L2 cache memory of 1000 KB (1 BM). The CPU static L1 cache can store information at 128 KB. When this L1 cache is consumed upon computer operation, L2 cache can store up to 1000 KB of data for processing and file swapping. With Athlon X2 Dual-Core QL-64 wattage rate of 35 watts, it reduces the chance of having processor overheat. It also consumes power at a lesser rate almost half of common Intel multi-core processors.
