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.

UNICORE
UNICORE (Uniform Interface to Computing Resources) offers a ready-to-run Grid system including client and server software. UNICORE makes distributed computing and data resources available in a seamless and secure way in intranets and the internet.
UNICORE has special characteristics that make it unique among Grid middleware systems.
The UNICORE design is based on several guiding principles, that serve as key
objectives for further enhancements.
Abstraction: UNICORE users need not know details about the system that they
use. UNICORE provides abstractions for concepts such as application
software and storage locations. Thus, UNICORE allows seamless access to
heterogenous environments.
Security: UNICORE offers strong security based on industry standards such as
the X.509 PKI.
Communication over the internet is protected by mutual authentication.
Site autonomy: when making resources available on the Grid,
administrators keep fine-grained control about their resources. Local policies
are respected.
Ease of use: A powerful GUI client covers the most common usage
scenarios, such as application execution and multi-step, multi-site workflows.
Ease of installation: UNICORE is simple to install, with minimal external
dependencies. Quickstart bundles exist that allow to get up-and-running quickly.
