Hardware maker Nvidia has announced a new computer that has the power of a cluster of computers without the high cost.

Nvidia, working with several partners, Dell, Lenovo, Asus, Western Scientific, and others, has developed the Tesla Personal Supercomputer, using the graphics processing unit based on Nvidia’s Cuda parallel computing architecture.

Burton Smith, a technical fellow at Microsoft stated while there have been claims of desktop supercomputers in the past, “this time it’s for real,”

Nvidia claims computers using the Tesla C1060 GPU processor will have 250 times the processing power of a typical PC workstation, enabling researchers to run complicated simulations, experiments and crunching processes without the need for a supercomputing cluster.

This so-called "personal supercomputer" will incorporate anywhere from between two to four Tesla C1060 processors, made up of 240 stream processing cores.

A computers cluster can run a many times the cost of one of the Tesla-powered workstations. The Tesla C1060 card, available on computers Tuesday, will sell for $1,699, with desktop computer systems including the card selling for less than $9,995, said Andrew Humber, an Nvidia spokesman. The systems would run at a processing speed of four teraflops, or four trillion floating point operations per second.

"This represents phenomenal price/performance for computational researchers who have typically had to compete for time on expensive and power-hungry clusters," the Nvidia spokesperson said in an e-mail.

Several institutions, including the University of Illinois at Urbana-Champaign and Cambridge University,and the Max Planck Institute are already using GPU-based personal supercomputers.

“GPU based systems enable us to run life science codes in minutes rather than the hours it took earlier,” Jack Collins, manager of scientific computing and program development at SAIC-Frederick’s Advanced Biomedical Computing Center in Frederick, Maryland, said in a statement. "This exceptional speed-up has the potential to accelerate the discovery life-saving anti-cancer drugs.”

With most High Performance Computer (HPC) clusters and supercomputers are powered by conventional CPUs, Nvidia is betting that its general-purpose GPUs can offer the types of performance that scientists, researchers and other workers in the HPC market need now to run these types of massive workloads.

Using Two Monitors on One Computer

You might question why someone would use two monitors on one pc but there is an explanation.  Known as dual pc monitors, these have a number of benefits.  A great reason for using two monitors is for someone in the photography business.  For example, photographers working on digital photos, trying to view, study, and organize, using dual monitors is a great help.

With a dual computer screen, you can indeed double work and also desktop space.  One of the most common computer screens is the LCD.  These are aesthetically pleasing and they are very space efficient.  Therefore, someone who does not have much desk space would benefit from the LCD monitor.  Now, for people on a budget, a CRT screen is also a sensible choice but bigger.

When it comes to using a dual computer monitor, again the best benefit is for anyone in photography or an individual who works with graphics and digital images.  Some of the main benefits include:

Browsing a picture album, placing all pictures on one monitor in thumbnail view and then viewing the photos on a full screen on the second monitor whereby the photo could be focused and manipulated.

Editing images is also much easier by using dual computer monitors.  For example, one monitor can be used for browsing images on the internet or through some type of photo library and then with the second monitor, photos can be edited using a special software program.

Even staying current on email is a benefit of having two monitors on one pc.  For home businesses or individuals in corporate America, receiving lots of emails is common.  With two screens, one could display all new emails coming in while the other could be be used for other types of tasks.

The bottom line is that dual computer monitors have many of advantages for home users or individuals in the workplace.  While the pc speed would not advance, productiveness would since the person is able to stay better organized and multi task in a way like never before.  This trend has become so popular that it is becoming a normal part of buying a computer and screen.

Today, there are a number of pcs on the market that are engineered to support a dual computer screen without having to spend additional money or time in getting hardware set up.  Therefore, if you have a newer pc, you might already have the capacity to work on two monitors on one computer.  To check, look at the back part of the pc where you would observe two VGA connectors or DVI connectors, or in some cases, both.

If your computer is not engineered with a connector for working on dual computer monitors, then you can visit a local pc or electronics outlet and purchase the required hardware.  For this, often times the hardware can be installed by yourself but often times a professional’s help is needed.

The diagnostics that are associated with computers can help to identify any problem or failure that computers show when they are having problems. Diagnostics are used to test out the computer system, which includes both the BIOS and memory, software, and even the hardware that is attached to the computer.

The most common types of problems will occur when your computer is down to very low resources, which can either be a low amount of RAM, or a low disk space. These conditions are very common, and generally result in your computer running very slow. This can easily be fixed, all you have to do is defrag your hard drive, and get rid of some programs and files that you no longer use or need.

Almost all types of computer diagnostic software can find and fix just about any problem that you are having. It normally starts off with a BIOS examination, and goes on from there. PC diagnostics software can determine a lot from the BIOS, from the common settings to those that have a major impact on both boot up and performance.

No matter what you do, you should never modify or tamper with the BIOS settings, as it can lead to serious problems. If you do plan to modify or mess with your BIOS, you should always create a backup first, just in case something goes wrong. The BIOS settings can be very tricky, although they are responsible for a lot to do with your computer. If you have never been in the BIOS before, you really shouldn’t be modifying anything inside of it.

Depending on the diagnostics program that you are using, there will be several different features available. Right now, two of the most popular are Norton Systemworks and PC Doctor. Both of these programs offer full diagnostics software, good for fixing just about any software related computer program you can imagine.  

Once you run the program, you’ll be able to select the diagnostic test that you are planning to run. Some offer you a full system scan, which will scan your entire computer and then display any problems that you having. After displaying any problems, the software will normally give you an option to go ahead and fix it. As long as the problem is nothing serious, the diagnostic software can generally fix it.

The more complicated problems, such as hardware failures or hard drive crashes, are a totally different story. They will require a technician who is very experienced, that can rebuild the hardware. Diagnostic software can report hardware problems to you, although most of the time it is unable to fix it.

There are other computer diagnostic software that you run after starting the computer or rebooting, that will check everything from BIOS. These types are great, although the types such as Norton and PC Doctor are by far superior. They offer far more features, including defragment, cache cleaner, and the option to delete your temporary Internet files. These features are great to have, especially if you aren’t the technical type.

For more reasons than one, computer diagnostic software is the ideal way to find and prevent problems with your computer. Norton Systemworks offers you Ghost as well, which is the perfect way to back up your data. You can back up certain files, or just go ahead and back up your entire hard drive. Systemworks and Ghost are very easy to use, even if you are completely new to computers. For everything they offer you - computer diagnostic programs are the ideal way to prevent problems before they happen.

Most of us are not well versed in what we should do when something goes wrong with a computer. We use computers more than ever, and it could very well be something that becomes more and more important as we move on through time. Sadly, there are many small things that can go wrong, quite unexpectedly, that can mess everything up. Things are complicated to fix, even small problems, and we donít know what to do. Instead of panicking, we can always go to computer forums to get help from those that know what they are doing.

When you visit computer forums, there are some things you should know. You should have written down anything that had happened when you found a problem. That means if you had an error message, you should have written down the error number. That often helps someone give you a fix within seconds. Any other details can help, so have it written down so you can remember. However, before you post on computer forums about what happened, see if it has happened to someone else first.

That means you have to use the search function that you can find on many computer forums. This allows you to add a few keywords related to what your problem is, and then if anyone else has posted, it should come up in the search. Use different keywords before you give up on finding something. That would mean that you donít have to post about your problem at all, but follow the instructions that were left for someone else who came to the same computer forums with their computer problems. If the fix doesnít work, you can then post.

What you should remember about computer forums is that they are going to help you out, but they may not have a lot of patience because there are so many seeking information. If they tell you to do something, be sure to do it. What they ask can help them diagnose the problem, or are essential things you should do to fix your machine. Be sure to thank whomever helps you, as they often do it for free, or for very little cost. It saves you money in costly fixes in computer stores. Donít be afraid to pay a little for help if you canít find free help. A site with a good reputation will always give you what you pay for, and usually, much more.
