Supercomputers are said to be those computers which are at the forefront of computing power and some other matters at the present time. Equipped with state-of-the-art technologies, supercomputers can perform very large calculations and very minute calculations very quickly.
Several microprocessors work together to quickly solve any complex problem. The supercomputer is the fastest, most efficient and has the highest memory capacity among the computers currently available. According to the modern definition,those computers, which can operate with a capacity of 500 megaflops, are called supercomputers. Supercomputers can do a billion calculations in a second. Its speed is measured by mega flop.
The first supercomputer is Illiac 4, which started working in 1975. It was developed by Daniel Slotnik. It alone could handle 64 computers at a time. Its main memory could hold 8 million words and it could perform arithmetic operations in the ways of 8, 32, 64 bytes. Its working capacity was 300 million calculation actions per second, that means it could solve 300 million problems of addition, subtraction, multiplication, division in the time that we could barely count up to 8.
Human Brain Working
- The brain and the rest of the nervous system are made up of many different types of cells, but the primary function unit is a cell called a neuron. All sensations, movements, thoughts, memories and feelings are the result of signals that pass through neurons.
- Neurons have three parts. The cell body contains the nucleus, where most of the molecules needed for the neuron to survive and function are manufactured. Dendrites extend out from the cell body like branches of a tree and receive messages from other nerve cells. The signals then pass through the cell body to the dendrites and can travel from the cell body from one axon to another neuron, a muscle cell, or cells in another organ.
- The neuron is usually surrounded by many support cells. Some types of cells wrap around the axon to form an insulating sheath. This sheath may contain a fatty molecule called myelin, which provides insulation for the axon and helps nerve signals travel faster and further. Axons can be very short, such as those that carry signals less than the width of a hair from one cell in the cortex to another or the axons may be very long, such as those that carry messages from the brain down the spinal cord.
Main Functions of the brain
- Our mind has a very deep contribution in running our body or in taking any kind of decision. Our brain works to keep the heartbeat normal, prevent uncontrolled breathing, maintain body temperature and keep blood pressure stable.
- You can understand it in such a way that when we hear some good or bad news, our breathing becomes faster or the body temperature starts changing, in that case the brain controls it. Along with this, the brain tells us about the process happening around us by seeing, touching and tasting with the help of various senses.
- Our brain controls all these movements in what we are getting involved in, what we are responding to. The brain also gives us the power to think and understand.
How much of our brain do we use?
- Eventually this myth started getting veiled and people’s fabricated misconceptions started getting dispelled.
- American scientist and neurologist Barry Gordon said in an interview that “10 percent of the brain’s use is just (just in case definition) a myth, while almost the entire part of the human brain is always active.”A study published in Frontiers, the journal of human neuroscience, debunked the myth that 10 percent of the brain was used.
- According to the study, a normal brain has imaging technology. What is called ‘functional magnetic resonance imaging’ can measure when a person does different activities.
- By presenting many such examples, researchers have shown that almost our entire brain is used. Even if someone is doing simple tasks. Even when a person is resting or sleeping, almost the entire brain remains active.
- Overall, the truth is that our brain works 100 percent, with 90 percent of the glial cells powering the remaining 10 percent of neurons.
Indian’s First Super computer
- India did not have its own super computer till the 1980s, it was a period when the technological era had started in India.
- America did not want anyone to be able to match her. But by making “PARAM-8000” computer by the Center of Development Pune in India, we showed the world that we are no less than anyone, after this India gave supercomputer “PARAM-8000” to three countries Germany, UK, and Russia.
- In 1998, a super computer was built by C-DAC named “Param-10000”, its computing capacity was 1 trillion calculations per second, today India is the name of supercomputer in the world.
- A list of the world’s best supercomputers has been made, in which India’s name is at number four in the top 10 list.
IIT Kanpur is India’s First Educational Institution to Get a Supercomputer
This research will be done through the country’s first super supercomputer, which has been established at IIT Kanpur. Because this research required many times faster speed than supercomputers. This super supercomputer will run at the speed of 1.3 peta flops.
Efforts are being made to remove the problems of the society by doing new research continuously at IIT Kanpur. Now scientists are going to do research on unsolved natural disasters. For this, a super computer has been installed in the institute. An agreement has also been signed with Center for Development of Advanced Computing (CDAC) to operate it. With this super supercomputer, not only scientists will do research, but students of many educational institutions including the institute will get benefit. It will be run through internet. After IIT Kanpur, preparations are being made to install super supercomputers in IIT Roorkee and IIT Mandi as well. To promote research. Earlier two supercomputers have been installed in IIT Kanpur
How does a Super computer work?
- Supercomputers are used for scientific and engineering experiments that require extensive database and high level calculations.
- Supercomputers are very fast, powerful and expensive. That is why it is used where there is a need to do very large and fast calculations.
- Apart from this, it is also used in special operations, because there is a lot of time (race against time phrase meaning) constraints in special operations, they have to do more work in less time.
