In the previous post, we have seen that what are super computers and what are their uses? In this post we will see the top 10 super computers in the world…………..

• Rank 10 – Trinity – 8.1 petaFLOPS – U.S.
• Rank 9 – Mira – 8.5 petaFLOPS – U.S.
• Rank 8 – K computer – 10.5 petaFLOPS – Japan
• Rank 7 – Oakforest PACS – 13.5 petaFLOPS – Japan
• Rank 6 – Cori – 14 petaFLOPS – U.S.
• Rank 5 – Sequoia – 17.1 petaFLOPS – U.S.
• Rank 4 – Titan – 17.5 petaFLOPS – U.S.
• Rank 3 – Piz Daint – 19.5 petaFLOPS – Switzerland
• Rank 2 – Tianhe 2 – 33.8 petaFLOPS – China
• Rank 1 – Sunway Taihulight – 93 petaFLOPS – China

Super computers are the special type of computers who’s processing speed is extremely large than normal desktop PC. But why we need them? and who uses such a huge and powerful computers?

We need such type of huge and powerful machines for some specifics functions like simulation of universe over millions of years, safety and reliability of nuclear weapons, highly sophisticated scientific and mathematical calculations, bioinformatics, climate change observations, geo-scientific exploration and many other complex tasks which are literally impossible for normal desktop computer.

Next thing is how we will measure the speed of super computer? Will we have to see the clock speed or what? Answer is No. Super computer’s speed is measured in petaFLOPS.

1 petaFLOPS is equal to 10^15 floating operations per second.

You can understand it by imagine if you will do a one calculation every second for next 31,688,765 (Three crore sixteen lakhs eighty-eight thousand and seven hundred sixty five years) continuously without stopping, Super computer with 1 petaFLOPS speed will do it in just 1 second………….that much fast

In the next post we will see the top 10 super computer present in the world in 2017.

I hope you all know about the mother-boards.

For those who don’t know about the mother-boards, they are PCB (Printed Circuit Boards) which holds the processors, memory units and other peripheral devices in the computer and allows the communication between them.

So which company’s mother-board are you using in your laptop/ PC? If you don’t know check it, but after reading this article…..

Here is the list of world top 5 mother-boards manufacturers.

• Asus (Taipei, Taiwan)
• Gigabyte Technology (Taipei, Taiwan)
• MSI (Zhonghe, Taiwan)
• Intel (California, U.S.)
• AS Rock (Taipei, Taiwan)

As you can see Taiwan has 4 out of 5 top manufacturers of  the mother-boards in the world.
