The great thing about this day and age is that almost everything is at our fingertips. You can find out information on nearly anyone and anything in just a few minutes by doing a search on the internet. News travels extremely fast, and keeping in touch with friends, family, and business associates has never been easier. Some people find this to be a great and wonderful thing. Others find it to be a little scary.

Since everything is so easily available, it can feel at times like your life is on display. Companies are now tracking social media sites, and for some it can be disconcerting to see ads targeted to things that you have been searching for online.

Whether you find the availability of information great or disconcerting, most people do agree that it has made things a lot easier for many people. If you own a business, you can talk with business associates much easier, and you can also get customers from around the world with much less money going into your marketing than in previous times. For individuals, you can communicate much easier with friends and family. Not only that, but you can find the businesses that you want to deal with, and generally don’t have to worry too much about how close or how far they are from you. If you are in school, having the information available that the Internet can provide is extremely beneficial. Writing papers for school has never been easier.

Feeling about privacy issues on the Internet vary from person to person. Most agree that privacy is a concern online, because of everything that is readily available. Others find that it does not matter too much, simply because that information has always been available.

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.

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.

Cluster Computing Software is the Heart of the System

Chances are if you work in an office, you have an IT person behind the scenes who keeps everything running smoothly for you. When you sit down at your computer, there are probably a lot of things going on of which you are not even aware. For example, your company may be using cluster computing software. How does that make you feel?

Actually, don’t let that frighten you. If your company is running a computer cluster, that software is what makes your computer play nice with the other ones in your office. The cluster is a system in which at least two computers are linked together to work in conjunction together. They share resources to make data processing faster.

You have heard of the Windows operating system, haven’t you? That’s what makes your computer work when you turn it on. It gives you all the nice windows and buttons so you can tell Windows what you want your computer to do for you. The operating system is real handy.

Well, because your boss is running a computer cluster in your office, that cluster needs software — an operating system — to tell all of the other computers what to do. It’s the trickledown effect.

It may seem complicated, but it’s really not. Essentially, the cluster software controls what the computers do. It tells them when to perform jobs, process data, run errands and make coffee. Well, maybe not that last part, but some geek somewhere probably has his computer set up to do that.

That’s about it. Cluster computer software keeps everything running smoothly behind the scenes. By the way, the reason your boss is probably using a cluster in the first place is because it is less expensive than buying one great big mainframe computer. Now that you know that, you don’t have to be so shy about asking her for a raise.

A Simple Explanation of Cluster Computing

At first, trying to grasp the concept of cluster computing can be a bit difficult for those new to the idea. If that is your case, it is not your fault, and you are not alone. We all suffer from occassional information overload, and it seems to put a big stop sign right in front of our brains. Maybe this simple explanation of computer clustering will help.

We have a wonderful election system in the United States, but now and then something goes wrong and the elections don’t go as smoothly as hoped. There have been occasional incidences in some cities in which it was learned that the voting machines were faulty. This put quite a hardship on the poll workers because that meant that all of the votes had to be counted by hand.

Now, just imagine if there was only one available poll worker. It would take that worker an undetermined amount of time to count all the votes. It would be unfathomable to hope to get the job done in due time.

The way it was handled was that many workers united to count the votes. This made the process much faster, and the work was eventually completed. It was completed much quicker than if one person did all of the counting alone. That is how cluster computing works.

If it were a computer performing the task, one could have eventually processed all of the data. However, many of them linked together make the job more thorough and much faster. If twenty computers are used, the work can be done at least twenty times faster.

With any luck, that will clear things up a bit for you. You should now put your new knowledge to good use. If your company is set up for cluster computing, when you go back to the office tomorrow, the first thing you should do is tell you coworkers that they can all work faster because you are there.

Deciding Upon Cluster Computing or a Mainframe Computer

Image via Wikipedia

If you are a business owner, or just starting up a new business, you certainly know by now that you have a lot of decisions to make. Any choices that you make now can affect your company for years to come. Choosing the right IT setup is one of those. If you plan on having more than a few workers and doing some intense processing with your computers, you will have to decide whether to go with cluster computing or a mainframe computer.

If your place of business is just a simple office with a few employees, you may not have a need for high performance computing. Maintaining a simple database, running a few software programs, sending e-mails and having a small network is not anything that a traditional setup cannot handle.

On the other hand, if your industry requires intensive data mining, the handling of statistics and heavy number crunching, you will need the appropriate processing power. Both kinds written about in this article can provide that kind of performance.

One difference between the mainframe and the cluster is the cost. The former is considerably more expensive. The latter is more of a “pay as you go” system, meaning that you only add what you need now and can add more later as you need the additional performance.

You could say that opting for a mainframe computer is more of a commitment. That’s not to say that it is bad, just that it is expensive. Cluster computing is less costly because it is based on traditional desktop computers that are linked together to combine their performance.

If your company is going to be massive and grow quickly, a mainframe computer may be the only way for you to go. On the other hand, if you expect growth but at a slower pace, you best option may be cluster computing. That way you can add more processing power as your company needs it.

Companies are always looking for ways to save money and be more efficient. This has inspired them to look at some ideas regarding Internet and cluster computing that have enlightened them to some good possibilities. Many of these companies are starting to make good use of computers that are inactive.

Internet computing is essentially using the Web to access a database to process information. The processing is done via a software program that uses the processor of an otherwise dormant computer. A unit that is used for work for eight hours per day, and then shut down for sixteen hours, can effectively use those sixteen hours to run tasks and perform calculations.

Internet computing allows for computers all around the world to be logged into a database to perform this work without the need of a huge network. The network is, in effect, the Web. All of the processors working with that database are essentially the computer cluster.

Companies and organizations using this kind of system include colleges, government agencies and private institutions. Much of the work being done involves research and the processing and analysis of research data. Some of these organizations are for profit; some of them are nonprofit.

It is common for the nonprofit organizations to use private desktop computers to do their Internet computing. Some of them do interesting and important scientific research that intrigues some people who sympathize with the cause of these groups.

Because of this, those people may volunteer to allow their processors to be used during their machine’s normal down time. This cuts a lot of corners for these organizations by saving them money and an extraordinary amount of time that it would normally take to do this kind of work.

As fast as knowledge already grows, it makes a person wonder what is on the horizon. With the help of Internet and cluster computing, we will see enormous advances in the fields of science and medicine in our lifetimes.

A Simple Introduction to Cluster Computing

IT or information technology departments are constantly looking for ways to make their computers produce the maximum processing power. Usually the departments are working under limited or restricted budgets. However, many companies are asking that these departments provide large amounts of this processing power to meet their needs in terms of applications, knowledge management, databases and more.

Business process such as database management rely heavily on IT resources for daily computing processes, but as was stated the budgets of these IT departments are usually not large enough to keep up with their company’s demand for more and greater computing power.

A great number of the major business enterprises today actually would require the processing and computing power of a supercomputer. However, very few of the companies have a super-sized budget for such computers.

Because of this need for processing power on one hand and the budge constraints on the other, many companies and their IT departments are turning to computer clusters. Computer clusters are networks of cheap, yet very high-powered desktop computers.

There are many different types of computer clusters such as high-availability clusters, load-balancing clusters and high-performance clusters. Each of these different types of clusters has different designs and configurations for different computing scenarios.

The benefits of computer clusters include:

–Higher processing power. These clusters can be more cost-effective than a mainframe, providing a higher return on investment.

–Network technology improvement. In addition to the reduction in cost, these clusters are driving the implementation of new and improved networking technology.

–Scalability is probably the biggest advantage to these computer clusters. These clusters can be expanded very quickly, while traditional mainframes cannot with out greater expense.

–Reliability. The entire computing system with in a department or company will go down if the mainframe computer fails. However, with clusters a node or single computer can fail and the system can continue by transferring services to another node.

A Look at Software Piracy

We’ve all heard the term software piracy. But how much do you really know about it? The “unauthorized” duplication of software is considered software piracy. Most of the general public is aware that the unofficial duplication and usage of software is considered illegal, a good number of people simply ignore that fact.

Software is considered to be a valuable intellectual property and should be treated as such. The Business Software Alliance and the Annual Global Software Piracy Study recently release numbers that state that the loss in revenue due to piracy went above $50 billion.

There are many different types of software piracy:

–Upload/download. This is a common for of piracy where users make illegal copies of software available to others via online services.

–Counterfeiting. This is the process where software is duplicated and sold in forms that make it appear they are true, legal copies.

–Unbundling. This is where a vendor sells software that was intended to accompany a specific hardware system.

–Soft-lifting. This is were a user purchase a single legal copy of a software program, but then installs the same copy onto several computers.

–Hard-disk loading is where unauthorized software is loaded onto hard disks. A common scenario is a hardware dealer will load this software onto computers to entice buyers.

–Renting. This is much like video rentals, except that it is unauthorized software.

Many of us believe that piracy has no victims; however this is patently untrue. As stated above the cost of software piracy is more than $50 billion in revenues due to developers. Another myth is that the copy protection placed on some software makes it more expensive. These costs are minimal when compared to the losses. When developers do not lose money to piracy they can then afford to produce better software at more competitive pricing.

Social Media Sites, Marketing and IT

The jobs of information technology managers are not getting easier. Many corporations are struggling with the advent of social media and how their organizations can benefit from them, as well as having to address the security issues of these sites.

A lot of companies do not allow access to these sites from an internal standpoint; and others may tell their employees that they are not allowed to discuss the company on these sites, even during personal, private times.

The jump was very, very fast from traditional media such as radio and print to the Internet and social media. And it’s not something that is going to fade away after the initial excitement. And interestingly, IT departments are uptight about social media, while the marketing department of the same company is trying to exploit these sites to the company’s advantage.

We understand there’s a certain appeal to social networking and media. And believe it or not, social media is considered to be part of Internet addictions. There’s also the “generation gap” of the Internet — older workers think that there should be no distractions during the workday; while the younger generations expect to be distracted.

On things companies should be aware of when denying internal access to social media is that it can actually set them up for other security issues. If employees really want access it is possible that they will come up with a solution to override the permissions and get on those sites anyway. These actions will basically open up security issues and may make the company’s network even more vulnerable.

Also there is disengagement between online behaviors that are secure and the lightheartedness of social media.

Companies need to create guidelines and implement policies that won’t prevent them from gaining new customers and communicating with existing clients.
