Grid is a new Information Technology (IT) concept of "super Internet"
for high-performance computing: worldwide collections of high-end resources
- such as supercomputers, storage, advanced instruments and immersive environments.
These resources and their users are often separated by great distances
and connected by high-speed networks. The Grid is expected to bring together
geographically and organisationally dispersed computational resources,
such as CPUs, storage systems, communication systems, real-time data sources
and instruments, human collaborators.
The "plumbing" of the Grid is essentially in place: there are already have large-scale networks of distributed computers, connected by a (comparatively) reliable networks using data communication protocols (TCP/IP etc) that are commonly agreed and widely used. However, because many of the enabling technologies have not yet been developed, the challenges of projects like Globus development team, for example, has created a set of underlying Grid services and a software toolkit for using the geographically distributed resources on Grids. You can find here some more examples of grid applications. |
