Top 10 Supercomputers in the World

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.

Computer Care Basics

The most basic of things are usually those that people tend to overlook. Desktop and laptop computers are becoming more and more important to people but then, most of the computing public almost always do not observe proper computer care. This blog debut is supposed to remind you that if you care for your computers enough, you would be keen to observe these things:

Know what you're working with. The computer unit you have sure came with a manual so it would help you best if you get yourself familiar with everything that's written there so you would be able to easily address the difficulties that your computer would be giving you. If you are having a hard time understanding the technical terms, not to mention the jargon that only computer experts can understand, you can always contact an IT equipment solutions provider.

Tech resources can be right under your noses. Know where to get help. Get acquainted with tech savvies. Making friends that are computer experts can be your ticket to not spend too much on maintenance and repairs. However, I am not telling you to depend on others forever. Developing your computer maintenance skills would always be wiser. In order for you to do that, you could use some reading online or you could skim through online forums and computer equipment support groups as it is most probably that other people have already experienced having the same computer problem you usually have. Try contacting computer rental companies too. Who knows they could actually give you the best solution to your technical dilemmas.


Computer Care Basics (Continued)

Prevention is always better than cure. Yeah, that is a cliché but that would be so true when it comes to caring for your computer. The most important thing you should do to take care of the security and the health of your computer is to take precautions. Avail of any protection software you can get - virus protection, firewalls, etc. It would also be best for you to have back-up files so work would not be disrupted in case of uncalled for system failures. You may always ask the experts for help. IT equipment rental solutions providers are one of those that can offer you with helpful knowledge regarding computers and other audio visual equipment.

Take a hint. Computers that freeze in the middle of whatever it is that you are working on are telling you that something is wrong somewhere within its system. Be keen enough to acknowledge the signs. Check your computer even before system damage goes worse. Rebooting would most probably solve the dilemma for a while but it would be best if you really knew the reason behind your unit getting a bit inefficient. Also, make sure that your hard disk isn't full. Low memory spaces usually cause poor computer performance.

Get organized. You do not necessarily have to be a neat freak to know that working with an organized system would be easier and faster. The "My Documents” portion of your system allows you to create a virtual filing cabinet. Do not stack all your files in your desktop. I tell you, a messy desktop could and would hinder you from getting your tasks completed in a shorter period.

This goes out to people who use computers on a regular basis. Whether you are using your own computer unit or rented desktop computers or notebooks, you can always refer to the guidelines mentioned above.
