Grid Computing
Grid Computing
Applying the resources of many computers in a network to a single problem at the same time �¢?? usually a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data. Grid computing uses software to divide and farm out pieces of a program to as many as several thousand computers. A number of corporations, professional groups and university consortia have developed frameworks and software for managing grid computing projects.

GRIA
GRIA is Grid middleware which enables use of the Grid in a secure, interoperable and flexible manner.
GRIA makes use of business models, processes and semantics to allow resource owners and users to discover each other and negotiate terms for access to high-value resources.
GRIA implements an overall business process to find, procure and utilise resources capable of carrying out high-value, expert-assisted computations.
By focusing on business processes and the associated semantics, GRIA enables users to provision for their computational needs more cost effectively, and develop new business models for some of their services.
Services from different providers can be combined together to create applications using a simple and easy-to-use API.
GRIA provides several software packages that can be downloaded free of charge, each designed to address a particular business need.
The basic application services package allows an organisation with cluster computing facilities to provide data storage and processing (using applications installed on the cluster) for trusted users
The service provider management package adds support for service level agreements to manage and if necessary bill for service usage, via a simple management protocol that can be used with other (non-GRIA) application services, if required.
The client package allows users to access GRIA application services via simple desktop applications, including negotiating with service management facilities (if present), and provides a simple application programming interface (API) for development of integrated applications that use such services, if required.
The client management package, that adds support for organisation-level management of service users, including authorised sign-off for service level agreements including billing terms, and centralised control and monitoring of which users can procure and access services.
