We will try to understand what supercomputers are, how they evolved, function, and their incredible applications across various domains. So, get ready to dive into the fascinating realm of supercomputers or the future of the world.

What are Supercomputers?

Supercomputers are cutting-edge computing systems designed to process vast amounts of data at unprecedented speeds. They stand at the paramount of technological innovation, harnessing parallel processing to tackle complex problems that traditional computers struggle to solve. 

In essence, supercomputers are the superheroes of the computing world and hold enormous computational power to revolutionize numerous fields.

How have Supercomputers evolved?

Supercomputers have come a long way since their inception. The journey began with room-sized mainframes in the 1940s, gradually evolving into specialized vector processors and parallel computing machines.

We will also discuss 10 examples of supercomputers that grew in time.

The Cray era: mid-1970s and 1980s: Cray-1 in 1976, became the most successful supercomputer in history. Cray-1, which used integrated circuits with two gates per chip, was a vector processor. 

In 1985, Cray-2 was released, which used four processor liquid-cooled computers wholely immersed in a Fluorinert tank, Cray-2 was the first to break the gigaflop barrier and reached 1.9 gigaflops.

The 1990s witnessed the rise of massively parallel processing, paving the way for modern-day supercomputers that integrate thousands of processors working together. In the first decade of the 21st century, we saw significant progress in the efficiency of supercomputers and their power consumption.

NEC built Earth Simulator for JAMSTEC(Japan Agency for Marine-Earth and Technology) in 2004 which reached 35.9 teraflops, using 640 nodes, each with eight proprietary vector processors.

China’s supercomputer Tianhe-1 gained the top spot in 2010 with 2.5 petaflops.

Japanese K computer in 2011 became the fastest in the world with 8.1 petaflops, using over 60,000 SPARC64 VIIIfx processors housed in over 600 cabinets. Also, it was over 60 times faster than Earth Simulator.

Summit had become the world’s most powerful supercomputer, at 200 petaFLOPS by 2018 and in 2020 the Japanese once again took the top spot with the Fugaku supercomputer, capable of 442 PFLOPS.

This relentless evolution has made today’s supercomputers exponentially faster and more capable, marking a remarkable milestone in the history of computing. Above are some good supercomputer examples.

How Supercomputers Work?

Unlike traditional computers how do supercomputers are so powerful? The answer is parallel task performing ability makes their processing super fast, this approach rapidly boosts their data processing capacity to an extreme level and allows them to perform modeling and data analysis. Their speed is measured in flops.

This approach significantly boosts processing speed and allows them to perform intricate simulations, modeling, and data analysis. Their architecture is customed so that they can handle large datasets and complex tasks easily.

Serial processing:

In this processing, tasks are executed one after the other, once the first is completed then the next will be executed. Simply one by one task to be performed, it doesn’t matter how fast the other task is processed order will be followed. This is known as Serial processing somewhat similar to our normal computers

Parallel Processing

Modern supercomputers perform work much more quickly by splitting tasks into pieces and working on separate tasks at the same time, this is known as parallel processing. Once the divided task gets completed, the final result is combined, and we are also capable to do parallel processing up to some extent.

Massively parallel processingSupercomp-c

Parallel processing opened the way to add more and more no of processors, even adding one hundred or thousands. Supercomputers have been routinely using thousands of processors, which is known as massively parallel processing. But, it leaves us with the problem of assembling them in the most efficient way for maximum output. Maybe, a centralized system to split problems and assign controlled workloads among processors can help. Still, the quest is on to find the most efficient way.


Making a cluster is a way of making a supercomputer where a giant box is filled with processors and so they cooperate to solve complex problems through massive parallel processing.


Here supercomputer is made by connecting computers located in different places through the internet, which means computers are spread across multiple locations instead of being located in the same place.

Applications of Supercomputers

Due to its exceptional capability to solve human problems, we are still trying to advance them beyond our imagination level. Their results are amazing in almost every aspect, 5 uses of supercomputers are discussed below:

Weather Forecasting

Lately, the weather has been the most unpredictable thing around the globe, but thanks to our supercomputers that help in predicting, and calculating to get accurate information, hence minimizing loss.

Supercomputer collects data from satellites, and weather stations and create complex atmospheric models to help us understand the worst situation coming.

Helping government and communities to prepare for extreme weather conditions(cyclone, drought, flood, tsunami, etc ) and reduce potential damage.

Scientific Research

These high-performing supermachines are indispensable tools to accelerate our research that drives innovation and pushes the boundaries of the human world.
