Supercomputer

In News
  • India will soon acquire its fastest Supercomputer worth Rupees 900 crore and it is expected to start functioning by March next year.
About Supercomputer
  • The new computer can improve forecasting from 12 to 6 kms. Compared to the Cray XC-40 supercomputer ‘Mihir’ with a performance of 6.8 petaFLOPS (PFLOPS),
  • India’s fastest supercomputer at present, the new supercomputer will have nearly thrice the capability, viz 18 PFLOPS.
  • The facilities at this world class centre will benefit all sectors, all sections of the society, in fact every individual of the country is going to get the benefit directly from this institution.
Features
  • Supercomputers have certain distinguishing features. Unlike conventional computers, they usually have more than one CPU (central processing unit), which contains circuits for interpreting program instructions and executing arithmetic and logic operations in proper sequence.
  • The use of several CPUs to achieve high computational rates is necessitated by the physical limits of circuit technology.
  • Electronic signals cannot travel faster than the speed of light, which thus constitutes a fundamental speed limit for signal transmission and circuit switching.
  • This limit has almost been reached, owing to miniaturization of circuit components, dramatic reduction in the length of wires connecting circuit boards, and innovation in cooling techniques (e.g., in various supercomputer systems, processor and memory circuits are immersed in a cryogenic fluid to achieve the low temperatures at which they operate fastest).
