The Grid

The Grid is an infrastructure for enabling the integrated, collaborative use of high-end computers, networks, databases, and scientific instruments owned and managed by multiple organisations. e-Science refers to large scale science carried out through distributed global collaborations enabled by the Internet. Grid technologies form the underpinning and enabling middleware (i.e. services that support a set of distributed applications) for pursuing e-Science.

The Global Grid Forum is a community of individual researchers and practitioners working on distributed computing, or "grid" technologies. Their web site includes links to Grid initiatives and projects and working groups.

Globus

The Globus Project is developing fundamental technologies needed to build computational grids. This includes the Globus toolkit for working with the Grid.

Condor

Condor is a High Throughput Computing environment that can manage very large collections of distributively owned workstations. It can manage dedicated clusters and make use of pre-existing resources such as PCs on people's desks. When a job is submitted to Condor it finds an available machine in its organisation’s pool to run that job.
