Supercomputer means a computer which is many times more powerful and faster than a normal computer. These supercomputers are used for special tasks, such as scientific research, weather forecasting, nuclear energy research, artificial intelligence, and space exploration. Supercomputers are owned by different countries around the world and are used in different areas of research and development. Let us understand supercomputers in common language and know how they work and for what purposes they are used.
Introduction to supercomputer and its working method
Supercomputer is a computer system which is so powerful that it can do millions of calculations in a single second. The processing power of supercomputers is many times more than that of ordinary desktop or laptop computers. Supercomputers are equipped with thousands or millions of processors which do parallel processing, meaning they can do many calculations in a single time. This is the reason why supercomputers are the fastest computers in the world.
Just like we use ordinary computers for everyday work like surfing the internet, playing games or storing files, supercomputers can also do such basic things but that is not their main work. The work of supercomputers is very specialised and advanced. They are used in scientific and technical works which require massive data processing and high-speed calculations.
High-speed processors, vast memory, and fast interconnection networks are used to design supercomputers. These computers are made by combining several CPUs in a single system and their architecture is also different from normal computers. 'Parallel processing' is used in these, in which a task is broken down into smaller parts and processed on different processors. They perform all calculations quickly and analyze data, which is not possible with an ordinary computer.
History of Supercomputers
The history of supercomputers begins in the 1960s when Control Data Corporation (CDC) developed the first supercomputer. The name of this supercomputer was CDC 6600 and it was designed by Dr. Seymour Cray. It was the fastest computer in the world in its time and it gave birth to a new revolution in the world of computing. Dr. Cray is also called the "Father of Supercomputing".
Seymour Cray built several supercomputers in the 1970s and 1980s, and after that big companies such as IBM, Fujitsu, and Hitachi also entered the field of supercomputing. As technology developed, supercomputers became more advanced and powerful. Today, IBM's "Summit" and China's "Sunway TaihuLight" are among the most powerful supercomputers in the world.
The supercomputer has been used in various fields
Supercomputers are used in different fields where their main work is to handle complex calculations and large data sets. Some special areas where supercomputers are used are mentioned below:
1.Weather Forecasting
Supercomputers play a very important role in weather prediction. Weather forecasting is a complex process that requires analysis of data of different factors of the atmosphere, such as air pressure, temperature, humidity, and wind speed. Supercomputers analyze this data and predict what the weather will be like. It also helps in predicting natural disasters like storms and cyclones.
2.Scientific Research
Supercomputers are also used in different fields of science such as quantum mechanics, molecular modeling, and physics. It is difficult to carry out experiments practically in fields like quantum physics and chemistry, but it becomes easy to prove theories and concepts by simulating them through supercomputers.
3. Medicine and Health Care
In the medicine and health care field, supercomputers are used to develop new drugs and vaccines. Today's advanced supercomputers help create new treatments and medicines by simulating the interactions of genes and molecules. Supercomputers were also used to develop the COVID-19 vaccine, in which they helped analyze the genetic structure of the virus.
4. Artificial Intelligence and Machine Learning
Nowadays artificial intelligence (AI) and machine learning (ML) are becoming popular in different fields of technology. Supercomputers are used to process complex algorithms of AI and ML and analyze data sets. For example, supercomputers are used extensively in training autonomous vehicles, face recognition technology, and natural language processing.
5.Space Exploration
NASA and other space research organizations also use supercomputers to solve many complex calculations and simulations that take place in space. These computers process astronomical data and analyze events that take place in space. They also help in studying black holes, galaxies, and planetary movements.
6.Financial Modelling
Supercomputers are also used in finance and stock market. These computers are used to analyze large scale financial data and predict market trends. Accurately predicting changes in the stock market is a difficult task but with the help of supercomputers, big financial organizations are able to predict the market's significance and analyze data.
Advantages and Challenges of Supercomputers
Supercomputers have many advantages which help in bringing advancement in many fields of the world. But they also have some challenges. Some advantages and challenges are given below:
Benefit
1.High Speed Processing:
The processing speed of supercomputers is millions, crores of calculations per second which is very useful in research and development.
2.Accurate Forecasting:
Supercomputers are used to provide accurate data and make predictions in industries including the weather, stock market, and health care.
3.Large Data Handling:
These computers are also used to process and analyze large data sets.
Challenges
1.Costly: The cost of supercomputers is very high and hence only advanced nations or large organizations can afford them.
2.High Power Consumption: They require a lot of electricity to run which is challenging for both cost and environment.
3.Maintenance and Upgradation: Maintaining and upgrading supercomputers is also difficult as it requires highly skilled professionals.
Supercomputing in India
There has been a lot of progress in the field of supercomputing in India too. India has some advanced supercomputers which are working in many fields. India has its own supercomputer “PARAM” which was built by the Centre for Development of Advanced Computing (C-DAC). Today India has advanced supercomputers like “Pratyush” and “Mihir” which are used in weather forecasting and climate research.
India has now started a new initiative “National Supercomputing Mission” whose aim is to establish 70+ supercomputers in the country and make India self-reliant in the field of technology.
Conclusion
Supercomputers are a unique technology which is being used effectively in different fields of science and technology. These computers are not just a technology but a revolution which is going to give new directions to our coming future. The way new supercomputers are being developed, they are helping in new discoveries and advancement in many areas of the technological world. Supercomputers have inspired the world for new ideas and possibilities and they are an important part of our scientific and technological future.
