The fastest computer today

Racing to the future – Supercomputers of tomorrow

What is similar between Usain Bolt and Tianhe-2? Does the question sound a bit weird? Not at all if you know that we are talking about speed. The former as you all know is the fastest human on earth having won the World Championship in Beijing in end August 2015. Tinahe-2, the Chinese super computer has once again placed itself at the top of the list of 500 supercomputers of the world and has been recognized as the fastest computer today in the list published in July 2015.  Doing it three times in a row is no mean achievement for the giant computer that has been able to maintain its position on the list of Top 500 computers in the world that is prepared twice in a year. China seems to be pretty focused in retaining its position as it has increased its count of supercomputers by an impressive 20% over the figure in the last list that was published in end 2014.

The numbers

National Computer Center of China in Guangzhou houses Tianhe-2 that has clocked a speed of 33.86 petaflop per second. In plain words it means that this giant machine is capable of performing as many quadrillions of floating-point calculations in one second.

More than 50 percent of the Top 500 supercomputers belong to the US that boasts of 233 super computers despite a decline of 15% over the previous figure.  The combined figures of UK at 30, Germany at 23 and France at 27 fall behind China that aggregates 76.

Speed of development

The fast pace of development of super computers and the importance that countries attach to it can be understood by looking at the speedy evolution of the fastest computer. Barely five years ago, IBM was the first to cross the 1 petaflop per second mark and in such a short span of time Tianhe -2 has reached the unthinkable number of 33.86 petaflop per second. The US has set a goal of building the world’s fastest computer that would be 20 times faster than Tianhe-2 and the project is expected to be completed by 2025. Considering the stupendous pace of development, it seems quite possible that the world would get its speediest supercomputer capable of making one quintillion calculations in a second. If you are baffled by the figure, think it to be a billion, billion calculations just as you blink.

The way forward

For fulfilling its ambitious plans to capture the top slot of super computers, the US has set up the National Strategic Computing Initiative (NSCI), a nodal body to build the computer .The computer will not only be the fastest super computer but would be able to aid projects related to national security and scientific research besides performing complex simulations.  It is also expected to analyze X ray images to assist in diagnosing cancer and weather forecasts could become more accurate based on its analysis of weather data.

NASA could also use the powers of this supercomputer to design aircraft that is more sleek and streamlined without taking recourse to wind tunnel testing.


Features of Spyware and Malware

A lot of individuals relate spyware with viruses. It is true that spyware shares a lot of similar traits with viruses; however, a major difference exists. Originally, viruses were formed to eliminate the computer’s capability to operate.

After this, they turned into a tool which online thieves used to steal identities. In literally all cases, the computer’s owner knew that there was a severe problem. All this was changed by malware and spyware.

What Does Spyware and Malware Entail?

Spyware varies as it tries to attain some of the similar objectives of a virus without being noticed; it is more discreet. Spyware does not set out to cause destruction on the functionality of the computer; however, it may compile information about you.

Once more, even the information might be less dangerous than that which is necessary for stealing your identity. Actually, a lot of spyware functions to send advertising to your computer as well as install toolbars.

Why are Programs for Spyware and Malware Created by People?

What is the reason for any computer programmer to desire installing toolbars and delivering advertising secretly, rather than stealing your identity? The answer is pretty easy. Profit is still the motivation. But, hackers are becoming smarter about the way they profit.They are aware that stealing your identity and causing destruction to your credit is not just accompanied by heavy fines including time in jail but is also equivalent to destroy a factor that brings in profit.

Rather than making one person the target and taking all their money, the latest hackers are distributing spyware which pays them a tiny quantity, normally just a few cents, for every delivered advertisement. It is simpler to deliver spyware and malware to victim computers as a lot of users have no protection from spyware and malware. This signifies that hackers can benefit by distributing the spiteful program over a lot more computers.

How Spyware Affects Your Computer

You might wonder why you should be concerned yet spyware and malware are not a bother to you, since it is not coming from your individual finances. It is true that a lot of spyware and malware will not cause total destruction on your computer; but, your computer can become extremely disabled without the protection of spyware.You will note the impacts initially, as overall slowdown in all that you do. After some time, your computer might not respond for a long time. It might even make your computer crash time and time again. In essence, spyware works so that you are unable to efficiently utilize your computer as spyware is instead making use of it.

Spyware Security and Guard

So as to gain protection from spyware and malware, you need to get a program specially created for catching and defending your PC from spyware and a number of harmful malware. A lot of anti-virus programs recognize some spyware; however, they will not catch it all as they focus more specifically on viruses; this needs a slightly varied approach. However, a committed spyware program will provide you with complete protection from spyware as well as malware.



Spyware means exactly this; it is utilized for spying on your PC and your actions, without your knowledge. Malware signifies Malicious Software; this is something which disrupts your work on the PC. It can actually steal data also, using some of the viruses. Worse still, it can steal your money.




What to Expect From the New Apple Mac Pro

The introduction of Mac Pro has been a success story for Apple and also showing that the PC market is not yet outdated.

The year 2014 saw new reports of improvements in this apple mac pro. Customers may now be wondering what they can expect in this year. The new models are expected to come with very high tech features which will definitely attract more people especially those who like to work with complicated technology.

Top of the list when it comes to changes and improvements expected is the addition of Retina screen. Mac pro currently works with 1440×900 resolutions but it will clearly be no match for MacBook Pro Retina’s beautiful display, which gives the user a feel of being overwhelmed when it comes to the world of HD and beyond. This retina was expected to be introduced in the year 2014 but it did not happen as many expected. This is because Apple had to first work on the battery life and ensures that it has the strength to handle the amount of pixels that comes with the retina which demands a lot of power, thus draining the power at a faster rate.


It is because of this reason that they will have to use Intel’s new Broadwell CPUs which are also expected to arrive this year since it also delayed to launch in 2014. These chips come with advanced power consumption abilities which will help MacBook Pro launch its Retina Screen while enjoying the ten hour battery life as indicated in the statistics.

According to rumours, Apple will also introduce a range of three colors which are silver, space gray and space grey while breaking away from the silver livery making it like the current iPhone and iPad. This means that there will be a black Mac Pro with Retina screen. An idea that has many waiting for this big day.

The other thing that people are waiting for with baited breathe is the totally new look of the 12 inches MacBook which is expected to come with HD display. All these are reasons to look forward to the day there will be announcements of the launch of these changes.

There are many other things that are said to be in the pipeline and since it is too early to talk about them, many of those things are left for the customers to calculate till that day comes so as to end the speculations.

The changes are expected to help Mac pro stay in the competitive market that has seen many products launched and with very complicated technologies that have made the world a place of different technologies. This is also an indication that there are many inventors who keep coming with new ideas so as to remain useful and important in the competitive world.

Mac Pro is expected to attract many people after it has gone through these changes. 2015 is expected to be a year of change for those who like using Apple products, since there will be more changes in other different apple products.


The Fastest Computer System


There are many types of computer systems but the one that outshines them all due to its high speed is China’s Tianhe-2 super computer which runs at 33.86 quadrillion floating point actions per second.

A super computer is the top modern processing capacity which can run up to trillions of floating point operations per second. Super computers were introduced in the 1960s at Control Data Corporation by Seymour Cray together with other companies with the aim of improving the way computers operate.

The supercomputers that were first introduced used to operate only on a few processors and in the 1990s machines that operated using thousands of processors were introduced and there was even more computers that operated on tens of thousands of processors, so as to add to the efficiency of the previous computers. But out of all these computers that operate on tens of thousands of processors, Tianhe-2 remains the fastest computer system in the world, since November 2014.

The supercomputer has the ability to fully complete tasks within a short time thus saving time and making things easy for the user. This therefore means that it can be used in an office where time is of vital essence, this super computer should be able to do all the work without feeling the pressure. These super computers can operate using two different paths, the first one is that a larger number of computer machines on a network concentrate on solving problems with each machine assigned its own tasks that it is expected to complete and pass results via central server which puts together all competed tasks from all clients in one place.


In another part, the computers with large numbers of committed processors are kept close together so as to save the user from using a lot of time while transferring data thus making it better for the processors to work together. This therefore saves time and makes work fast and interesting since more will be achieved.


Working with these supercomputers is a good especially for big organizations that have many tasks that need to be performed within a short period of time. Having these super computers can make such organizations achieve more within a short period of time.


The super computers play a vital role in the field of computer science and technology and are used to achieve an extensive number of intensive tasks in different fields which include and not limited to molecular modeling, climate research, weather forecasting, oil and gas exploration, quantum mechanics and physical simulations. Molecular modeling is all about properties and computing structures of chemical compounds and also biological macromolecules, crystals and polymers.


With all these tasks, the super computer Tianhe-2 will have to step up so that it is not overtaken by a more powerful and fast computer system that may be launched in the future. For Tianhe-2 to stay in the market the manufacturers will have to keep coming up with new ideas that will improve its functions further, because the world of technology has progressed and it is very competitive.
