Top 5 Supercomputers in the World

Not for regular practice because of its usage and immobility, but a Supercomputer is certainly of great importance in today’s world. A gigantic machine racking up an entire room with myriad number of wires and buttons, this isn’t something one would prefer for their daily works, but on higher levels it has its own advantages.

What is a Supercomputer?

A Supercomputer is basically a computer with a very high-level computational capacity. It is expensive and requires a lot of space, as the name suggests. Though huge but it has great user advantages.  They are employed for specialized applications that require immense mathematical calculations. It’s best suited for weather forecasting, animated graphics, dynamic calculations, cryptanalysis and nuclear energy research and petroleum exploration.

The performance of a supercomputer is measured in floating points per second (Flops). With the turbulent advancement in the technology in the recent years, we are now able to access supercomputers with quadrillion floating points called Petaflops.

The Top 5 Supercomputers in the world are:

1. Mira in USA

Mira is a Blue Gene/Q based system with 48 racks and 786,432processors. It weighs 104 tons and has reached 8.59 petaflops per second.

Usage: It assists research in earthquake modelling, quantum mechanics, effects of cloud on the climate and material sciences.

2. K Computer in Japan

Twice the top 500 champion, K computer holds the number 4 position. It acheived10.51 petaflops/s and was the first computer to achieve 10Petaflops/second.  Seeing Japan’s technological advancements this might not come as a surprise.

Usage:  Titan is basically used for scientific purposes. It has the potential to exploit the hybrid architecture. It dealt mostly with molecular scale physics or climate models. Its modifications increases the degree of parallelism. The changes often yields great performances.

5. Tianhe-2 in China

This is the second time China has bagged the first place in Top 500 after Tianhe-1. Also known as Milky wave 2, it is the world’s number one system with a performance of 33.86 Petaflops/second. Its 16000 nodes with 88GB per node is a great memory boost.
