Grid computing
”The Computational Grid” is analogous to Electricity (Power) Grid and the vision is to offer a (almost) dependable, consistent, pervasive, and inexpensive access to high-end resources irrespective their location of physical existence and the location of access.
HISTORY
THE TERM COMPUTING ORIGINATED IN 1990’S AS A METAPHOR FOR MAKING COMPUTER POWER AS EASY TO ACCESS AS ELECTRIC POWER GRID.
THE IDEAS OF GRID WERE BROUGHT TOGETHER BY IAN FOSTER,CARL KELESSMAN,AND STEVE TEUCKER WIDELY REGARDED AS “””FATHER OF GRID””””
Scalable HPC: Breaking Administrative Barriers
WHY IS IT USED???????????????
USING A GRID
Title
A Typical Grid Computing Environment
ARCHITECTURE
A Layered View of a Grid
Computers, supercomputers, storage devices, instruments …
FEATURES……………
Grid computing is driven by five big areas:
Secure access: Trust between resource providers and users is essential, especially when they don't know each other. Sharing resources conflicts with security policies in many individual computer centers, and on individual PCs, so getting grid security right is crucial
Resource sharing: Global sharing is the very essence of grid computing.
Resource use: Efficient, balanced use of computing resources is essential.
The death of distance: Distance should make no difference: you should be able to access to computer resources from wherever you are.
Open standards: Interoperability between different grids is a big goal, and is driven forward by the adoption of open standards for grid development, making it possible for everyone can contribute constructively to grid development. Standardization also encourages industry to invest in developing commercial grid services and infrastructure.
How does a Grid Service work?
Client uses a Grid service interface
A grid service instance is created from a Factory with the help of a Registry
The grid service instances run with appropriate resources automatically allocated
New instances can allocated and destroyed dynamically, to benefit performance
Example: A web serving environment could dynamically allocate extra instances to provide consistent user response time
Simple Invocation Example
Grid: Towards Internet Computing for (Coordinated) Resource Sharing
Drug Design: Data Intensive Computing on Grid
It involves screening millions of chemical compounds (molecules) in the Chemical DataBase (CDB) to identify those having potential to serve as drug candidates.

Main components

REAL GRIDS……………………
Typical current grid
Virtual organisations negotiate with sites to agree access to resources
Grid middleware runs on each shared resource to provide
Data services
Computation services
Single sign-on
Distributed services (both people and middleware) enable the grid
