Presentation overviewA grid computer is multiple number of same class of computers clustered together. A grid computer is connected through a super fast network and share the devices like disk drives, mass storage, printers and RAM Operating system has capability of parallelism and a cost efficient respect to super computing

Grid computing combines computers from multiple administrative domains to reacha common goal, to solve a single task, and may then disappear just as quickly.What is Grid?HISTORY The termgrid computingoriginated in the early 1990s as ametaphorfor making computer power as easy to access as an electricpower grid.The ideas of the grid (including those from distributed computing, object-oriented programming, and Web services) were brought together by Ian Foster, Carl Kesselman, andSteve Tuecke, widely regarded as the "fathers of the grid".Early definition from Foster and Kesselman, 1998A computational grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational facilities

Related Technologies

The main idea to put some PCs together and get them to communicate.

Used to load balance traffic on high traffic websites.Used as relatively low cost form of parallel processing.

Cluster computing

The main idea is to connect with other computers.

Can access files from any computer on the network.Allows data sharing without going through central server.

Peer to Peer computingThe main idea is to connect many idle PCs on the Internet

Can perform other computations while not being used.

Internet Computing

Intragrid-comprised of a basic set of Grid services within a single organization.Extragrid-It based on bringing together two or more intragridIntergrid-It found in dynamic network access to the grid via the internet/WAN.Topologies of GridGrid computing calls for a shared environment on a common computer system from multiple administrative domains.Provides multiple domains, boost operation speed, distribution of resources convenient and enhance the existing resourcesComparison b/w GRID AND Cloud ComputingCloud computingis a branch of Information technology that invites businesses to become virtual.Provideshigh scalability, a complete secured environment, cost-effective and extremely reliable.CPU ScavengingCPU-scavenging, creates a grid from the unused resources in a network of participants. This technique uses pc instruction cycles that otherwise will be wasted throughout the day when the computer is waiting for user input or slow devices or during night.

For the segmentation of the grid computing market, two perspectives need to be considered: the provider side and the user sideThe provider side consist of grid-enabled market, theutility computing market, and the software-as-a-service (SaaS) market and enables the sharing of heterogeneous resources, and Virtual Organizations major companies are Sun Microsystems,IBM, andHP. The IT deployment strategy as well as the type of IT investments made are relevant aspects for potential grid users and play an important role for grid adoption.

Marketing segment of Grid computingGrids computing offer a way to solvefinancialmodeling,earthquake simulation, andclimate/weathermodeling. Grids offer a way of using the information technology resources optimally inside an organization. Grid computing is being applied by the National Science Foundation's National Technology Grid, NASA's Information Power Grid, Pratt & Whitney, Bristol-Myers Squibb Co., and American Express

Grid related project1)Grid Computing focuses on sharing of large scale of resources which are virtual to us , innovative applications and always on improving the performance.

2)Systems connected in a grid can be inexpensive and located world-wide, as opposed to High-End computing.

3)Enables an application to run on a different machine, whose existing machine may be busy.

Advantage of Grid Grid software and standards are still evolving Learning curve to get started Non-interactive job submissionLimitation of GridGrid computing is an effective way of managing a networked community. It allows a very speedy download of data and that too many files without collapsing the system. It works even on idle systems by tapping the CPU potential.ConclusionThank You.
