Grid computing is applying the resources many computers in a network with a problem at the same time Grid computing appears to be a promising trend for three reasons: (1) His ability to utilize more effectively the cost of a certain amount of computer resources, (2) As a way to solve problems that can not be approached without a large amount of computing power (3) Because it shows that many computer resources can be cooperatively and perhaps synergistically utilized and managed as a collaboration toward common goals. A number of companies, professional groups, university consortiums, and other groups have developed or are developing frameworks and software for managing grid computing projects. In the United States, the National Technology Grid is prototyping computational grid for infrastructure and network access for people. IBM, Platform, Avaki, entropy, Sun, HP) Grid architecture enables very popular projects such as e-Science project that demands Genome global interaction and networking in a recent survey of Chief Information Officer 500f are expected to use Grid technology this year Grid Computing: Features contributions from major players in the field Covers all aspects of grid technology from motivation to provide a guide application of state-of-the-art area in grid computing This is essential reading for researchers in Computing and Engineering,, statistical physics, engineers and mathematicians and IT policy makers.
