Yes, its here and most of us have also heard a word or two about it. But what exactly it is. Lets a a ride on grid computing.
Grid computing (or the use of a computational grid) is applying the resources of many computers in a network to a single problem at the same time – usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.
SETI (Search for Extraterrestrial Intelligence)@Home project in which thousands of people are sharing the unused processor cycles of their PCs in the vast search for signs of “rational” signals from outer space is a real big and famous example of grid computing. idea ek dum jhakas hai yeh……
The term Grid computing originated in the early 1990s as a metaphor for making computer power as easy to access as an electric power grid in Ian Foster and Carl Kesselmans seminal work, “The Grid: Blueprint for a new computing infrastructure”. The ideas of the grid (including those from distributed computing, object oriented programming, web services and others) were brought together by Ian Foster, Carl Kesselman and Steve Tuecke, widely regarded as the “fathers of the grid.”
According to wikipedia – Grid computing is a form of distributed computing whereby a “super and virtual computer” is composed of a cluster of networked, loosely-coupled computers, acting in concert to perform very large tasks.
Grid computing requires the use of software that can divide and farm out pieces of a program to as many as several thousand computers. Grid computing can be thought of as distributed and large-scale cluster computing and as a form of network-distributed parallel processing.
Now besides SETI the grid computing has found new area of work. The grid computing has taken the power of supercomputing for solving grand challenges like protein-folding analysis, climate modelling and earthquake simulation, with European projects spearheading the way. Researchers have created a system that allows managers to design and deploy business processes across a grid.
