A type of computer which is used to focus the applications that requires large mathematical and difficult calculations at front line of processing capacity is known as Super computer.
It is fastest computer as compared to ordinary computer because supercomputers involve solving advanced scientific problems. Supercomputers supported by high powered graphics workstations, which are extremely valuable resources for a wide range of scientific investigations. Fastest possible performance of such computers made them invaluable in for all types of scientific researches.
In 1970s, supercomputers were mostly run on scalar process principle but now to improve processes and efficiency new technologies are introduced such as liquid cooling, parallel file system, vector processing, striped disk and non uniform memory access. Currently there are many such types of supercomputers as the GRAPE for molecular dynamics and astrophysics and multiple other types which are used in tech industry these days.
Types of super computers
There are two types of supercomputer exist. One type has several extremely complex and expensive processors that carry out computations serially, one at a time and the second type has thousands of simple, inexpensive processors connected in parallel to perform the billions of task per seconds.
Applications of Supercomputers:
Due to high speed processing ability of Super computers, there are several applications of such computers which are used in scientific and research woks such as weather forecasting, graphics animation, nuclear research, petroleum research, molecular modeling and crypt analysis etc.
Today, Super computers are widely used in physics, precisely includes physical phenomena such as climate change, energy, environment, weapons, analysis of data such as national security intelligence, behavior of molecules in life sciences, protein folding, genome sequencing and also applicable on different kinds of medical industry.
Two major applications of supercomputers are Missile trajectory simulation and Gypsy moth growth population simulation.
Pros and Cons of Supercomputers:
There are many advantages of super computers which are really important for our daily life but at the same time where these computers have great advantages some disadvantages are also present.
Pros of Supercomputers:
- They can replace experimentation in the cases where experiments are hazardous, expensive or even impossible to perform or with the help of instruments.
- Help to design engineered products such as automotives, aerospace, nano-technology, and also new material designs by using up to 10,000 atoms.
- They are used to calculate and show the conditions, temperature, speed, voltages etc like we might be see in a power plant, traffic control office etc.
- Their use is of strategic importance to national security and defense, as well as for research and development in many areas of science and engineering.
Cons of Supercomputers:
- The construction of Supercomputers is an incredibly expensive task because user is charged according to no. of processors.
- They are not portable and are very specialized.
