Keep Your Computer at Like-New Speed

You may be accustomed to the scenario by now, but there’s little need to accept molasses-slow computer performance as a daily requirement to entering the digital realm. The Internet makes the world very convenient, so it’s essential to be able to access it and keep that very convenience available daily. When your computer starts to bog down like a car slowly getting stuck in the mud, it’s probably in the grasp of malware. Computers don’t necessarily get slower as they age, in the way that automobiles do. But they do appear to get slower with age, but that’s almost always because, somewhere along the way, they’ve picked up malware programs.

And that’s bad news, because malware is designed with the intent to do you harm, at the expense of having a more slowly operating computer, too! Malware are typically very small programs which affix themselves, uninvited, into dark spaces in your computer. They often run undetected, keeping track of your keystrokes – there’s not a much better way to hand someone your banking password than to let them see your keystrokes – and allowing the information there gathered to be used in whatever way the perpetrators desire. If you’re suddenly getting a rash of spam emails where in the past, you’ve not suffered this fate; it’s probably due to a new form of malware inside your machine.

Of course, all of this comes at a cost, besides the potential of an empty bank account! The latest, greatest computer that you paid out many hard-earned dollars for, suddenly doesn’t work at anything approaching a reasonable speed. That’s because malware programs freely use as much hard disk speed as they desire, leaving your legitimate programs with much less capacity to operate. Rather than wipe your hard drive and start all over with a system re-install, consider PC Tools Free Antivirus as a faster, easier solution. It will clean up the mess that malware tries to create.

Who Should Use High Performance Cluster Computing

Maybe you have heard the term and wondered what the big deal is about high performance cluster computing. After all, if it is something great, you sure don’t want to miss out. However, not everyone or every business needs this kind of horsepower. Then who does need it?

An HPC cluster is most often used in place of a mainframe computer. Sometimes it is done when a company needs a fast solution to a special computing need, and sometimes it is done to prevent having to lay out a large amount of money for a mainframe.

There are some companies that use their computers primarily as storage devices for data and as a communications tool. They may also do the books, log sales and file papers electronically with them. All in all, though, they have no great demand for any kind of intense computer processing.

On the other hand, there are companies that do some very intense work with their computers. Much of this work includes the heavy processing of data. They may have created their own software programs to analyze statistics or run tests on different things. These businesses need all of the processing power they can get.

A good example of a situation in which a HPC cluster might be used is in the forecasting of weather. It is hard to imagine all of the data that has to be “crunched” to get the accurate predictions for the nightly newscast.

Other companies that might have need for a HPC cluster might be financial firms; especially those that continually monitor the stock market so their agents can make predictions for their clients.

When it comes down to it, most of us don’t need high performance cluster computing like some of the big corporations do. We can get by with a nice, off-the-shelf system that will give us enough horsepower to read our e-mail, watch some videos and play some games.

Be Part of the Largest Computer Cluster in the World

Who has the largest computer cluster on the planet? The answer is out of this world: It is the SETI at Home program. If that is not ringing a bell, read on to see if it refreshes your memory.

The SETI at Home Program

SETI stands for the Search for Extra-Terrestrial Intelligence. SETI at Home is a unique program that clusters computers from all around the world together in the search for life in the universe. This is done by processing signals received from outer space. The hope is to discover certain radio frequencies that are not produced naturally.

However, it is such a big job that those who run it need a little help. Everyone who has a computer and an online connection can use his or her processor to be a part of the computer cluster that SETI at Home uses to process the signals. Those who help do not receive those signals directly, but log in process the data that has already been collected.

How You Can Help the Program

All you need to do is join the SETI at Home program. This can be done from the Berkley University of California Web site. Search for SETI@home. You will be asked to read the rules, and you will need to commit to running the application on your computer for at least two hours per week.

You will then download the software to your computer and install it. After that, it is a simple as opening up the program and running it. It can run unobtrusively in the background while you do other things. If you prefer, you can turn on the application when you are finished computing for the day. It can run at night while you sleep.

You, too, can be a part of the largest computer cluster in the world. Who knows, you might even be a part of history; it might be your computer that comes in contact with ET.

How Cluster Computing Can Save You Money

Cluster computing is a great way for new businesses or small business to save money while still getting enough computing power to handle their needs. It can be expensive to purchase a large computer to run a business. However, there is a more affordable way for small business owners to deal with this.

Cluster computing has become a popular way to get more processing power for less money. To give you an illustration of what it is, consider the game of tug of war. The more people you have pulling on one side of the rope, the more power you have. You no longer have just an individual’s strength, but you have the cumulative strength of all of the individuals.

That’s the way it is with a computer cluster. Single computers are linked together to form one large processor. This is effective because it saves a business owner from having to purchase a large mainframe to handle the needs of the company.

Now that personal computers are so much more affordable than they used to be, the owner can buy however many he needs to handle the job and, in most cases, still save money over the cost of a mainframe.

Computing clusters can be made up of as few as two computers. The owner can set up as many as he needs initially. As time goes by and his needs increase, more units can be added. There may come a time when a mainframe is more sensible, but in the beginning, this is a good way to go.

Anyone anticipating opening a business that will require computers should consider going the route of cluster computing rather than starting with a mainframe. It may be that a supercomputer is going to be required, but it would be a good idea to look into it before putting a lot of money into it.

Why Cluster Computing is So Flexible

One of the biggest expenses of running a business can be the cost of computers, networking and IT. After all is said and done, what may seem simple and affordable in the beginning can end up being very expensive. Purchasing a mainframe computer is a good example of that. It is not always necessary to start large, and there is a lot more flexibility with cluster computing.

Quite often, new owners are tempted to go all out on their IT systems, but that can get very expensive. At the same time, it is not actually known by them yet if an extensive IT system is going to be required. One of the great things about cluster computing is that it provides the ability to start with the exact system needed and build upon it as the office needs grow.

Computer clustering is so flexible that the IT system may never need upgrading to a mainframe. Another benefit to cluster computing is the innovation of cloud computing, which makes it easy for updates and repairs to be done over an entire network from virtually anywhere. This can help major computer companies from disabling the entire systems for hours at a time, which can essentially cost the company money, and sometimes clients. As more processing power is needed, more personal computers can be added to the system to supply it. This can be done many times over to satisfy whatever requirements come about.

The opposite is true as well. Sometimes an office needs to be downsized. If a mainframe is being used, it cannot be downsized. However, a computing cluster with twenty computers linked together can be trimmed to fifteen, ten, five or however many computers are needed to accommodate the system.

Good business owners keep a tight check on all aspects of the company. Cutting spending and carefully controlling money is one of them. Before an entrepreneur even opens the doors to the office, he should have a good idea what his IT is going to cost. In many cases, starting with cluster computing rather than using a mainframe computer is like putting money in the bank right away.

Why Cluster Computing is More Dependable than a Mainframe

The last thing any business needs is for things to break down or go wrong. There is rarely ever a convenient time. If anything has the potential to stop working, it is computers — and at the worst possible time. That is why cluster computing is more dependable than mainframe computing.

When a mainframe computer is being used, that is all there is. In other words, if it breaks down or quits functioning, there is no backup computer. The mainframe was it, and now it is gone. Outside of making some of the employees who get to go home early happy, this is not a good thing for the company. Work stalls or comes to a halt, and impatient clients can be angered or even lost.

On the other hand, if the business were using a cluster computing system, the problem described above would not happen. That is because another processor could just take over the work the failing one was doing. It happens without skipping a beat, and everything continues like clockwork.

To get a better understanding of this, imagine a string of Christmas tree lights that runs in parallel. When one of the bulbs in that string burns out, the others will still keep shining. The only thing that has to be done is to replace the burned out bulb, and the whole string will work again. In the meantime, everything but the one bulb kept working fine.

However, the mainframe computer would be more the like the lights used many years ago that ran in series. When one of them burned out, they all stopped working. It would be like that with the mainframe. When it goes down, the only processor that was being used stops working.

If your business absolutely must have its computers operational, and you are looking for a dependable system, consider avoiding the mainframe and go with cluster computing. That way your tree’s lights will never go out.

Using Cluster Computing to Make a Homemade Supercomputer

Most of us get by just fine with the home computers that we buy from our favorite electronics store. They are fast and able to do anything the average user needs to do: check e-mail, surf the Internet, read e-books and write documents. However, there are some things, like video games, that are more intense and may need the power of a homemade supercomputer. Cluster computing is a good way to get that kind of processing power at home.

It may be an exaggeration to refer to it as a supercomputer when it is in your home. After all, a real supercomputer is far beyond anything a user might have around the house. The big companies use them because they need the processing power to handle lots of data, transactions, communications, statistics and many other things.

However, all things tend to be equal when it comes to the amount of processing needed as compared with the amount of work that there is to be done. In other words, by setting up a computer cluster, a home user might have the equivalent of the supercomputer that a big corporation uses.

Linking two computers together can double the processing power that is being used to operate software and do calculations. Two high-speed processors can make a world of difference in the way a video game, for example, responds when being played.

Actually, the cluster doesn’t have to be limited to two processors. There can be three, five or ten of them; however many that are needed.

If playing intense video games is your thing, or if you need some heavy-duty processing power for any other reason, you might want to make a homemade supercomputer by using cluster computing. Even if you don’t truly need it, you might have fun setting everything up. Then you can show your friends your new hot rod.

Who Needs Computer Clusters?

Computer clusters offer several advantages, but that does not mean that they are useful within every context. Knowing when to use a computer cluster will help you allocate your resources so that you complete work efficiently without wasting time and money.

Computer Clusters at Work

Computer clusters are often useful in workplaces because they give lots of workers access to the same information. This makes it possible for employees to find the information that they need to complete specific tasks. Using a computer cluster at work can also help managers prevent employees from spending time on unrelated tasks such as playing games or browsing the web. They can, therefore, make employees much more efficient so that the company saves money.

Computer Clusters at Home

Video gamers will undoubtedly know that computer clusters offer big advantages when it comes to multi-player games. Gamers all across the world hold events in their homes so that several people can play graphic-intense video games at the same time. You can find them in every type of home from Phoenix apartments to farms in the countryside. Wherever gamers live, you are likely to find them taking advantages of the benefits that computer clusters offer.

Computer Clusters at School

Computer clusters are terrific computational machines. Allocating the resources of several computers to a single problem reduces the amount of time that it takes to compute large amounts of information. Although your typical high school student probably won’t need a computer cluster, someone studying physics and theoretical math at the graduate level will find that computer clusters offer several benefits. Instead of spending weeks trying to solve a single problem, a computer cluster can provide the answer within a matter of minutes or hours. They are, therefore, imperative research tools for those studying science and math.

Deciding What Computers to Use for Cluster Computing

Because of advances in technology, cluster computing has become more common for business that need the processing power but don’t want to invest in large expensive computers. Most of the time, this saves them money and affords them a lot of flexibility in how they handle their IT affairs. Of course, the other decision they have to make is regarding what machines should be used for a computer cluster.

Computers are more advanced and more affordable now than ever before. What used to cost thousands of dollars can now be had for a matter of hundreds; and it is much more sophisticated and faster. This is a great thing for a company that needs to purchase several computers to build a cluster.

However, the downside to purchasing a new one is that it can become outdated so quickly. New, faster processors are always being developed; new hard drives can hold more data; RAM becomes more advanced. It becomes nearly impossible to keep up with them.

In addition to that, as they get faster and able to provide more memory and storage, software gets more bloated and requires even more speed and memory. It’s like a never-ending battle.

The way to prepare for this is to purchase the best computer available. More importantly than that is to get a computer than can be easily upgraded. Many that the large manufacturer’s make cannot be easily upgraded. A lot of money can be saved later by purchasing one that is nonproprietary. That means that more memory, better hard drives and a better processor can be added later.

Choosing to go with cluster computing rather than to invest in an expensive mainframe computer can be a wise thing to do. Businesses that need room for growth will be able expand their processing power as the business necessitates. In the end, these companies will save money and have a more reliable system in place.

Parallel Computing and Cluster Computing

Thanks to scientists, engineers and large companies taking advantage of capitalism, the speed of our computers increases constantly. Unfortunately, so does the work load brought about by more intense software. With that in mind, private users and companies are always looking for ways to make computers work faster. Some opt for either parallel or cluster computing. So, what is the difference?

What is Cluster Computing?

In a nutshell, it is the linking of multiple computers together to work as one unit that is more powerful. Each one handles its share of the processing, thus the workload can be done twice as fast. The network can be made larger by adding more nodes, or computers, to the system.

What is Parallel Computing?

This is done with multiple processors. Computer clusters are a form of parallel computing, but the latter is more regarded as one unit with multiple processors. This is called dual processing. It is in essence the same thing as a cluster, but it is inside of one unit.

Actually, a computer with a dual processor could be used to make a cluster. However, a private user would not be as likely to use that configuration as a business might. Dual processors on a home system are plenty fast to handle anything that an average user would do, and more.

It essentially comes down to the “two heads are better than one” theory with parallel computing. As far as cluster computing, it is more like “it is less expensive than a mainframe.”

Either way, more processing power will be available. A large company will be more likely to set up cluster computing because it gives them more options to expand later. A private user could go that route, but it would be more feasible and less expensive to opt for a computer with a dual processor.
