13 Facts About Grid computing

Grid computing is the use of widely distributed computer resources to reach a common goal.

Grids are a form of distributed computing composed of many networked loosely coupled computers acting together to perform large tasks.

One feature of distributed grids is that they can be formed from computing resources belonging to one or more multiple individuals or organizations.

Grid computing middleware is a specific software product, which enables the sharing of heterogeneous resources, and Virtual Organizations.

Utility computing is referred to as the provision of grid computing and applications as service either as an open grid utility or as a hosting solution for one organization or a VO.

Grid computing-enabled applications are specific software applications that can utilize grid infrastructure.

CPU-scavenging, cycle-scavenging, or shared computing creates a “grid” from the idle resources in a network of participants.

Term grid computing originated in the early 1990s as a metaphor for making computer power as easy to access as an electric power grid.

The power grid metaphor for accessible computing quickly became canonical when Ian Foster and Carl Kesselman published their seminal work, "The Grid: Blueprint for a new computing infrastructure".

In 2007 the term cloud computing came into popularity, which is conceptually similar to the canonical Foster definition of grid computing and earlier utility computing.

Indeed, grid computing is often associated with the delivery of cloud computing systems as exemplified by the AppLogic system from 3tera.

The European Grid computing Infrastructure has been used for other research activities and experiments such as the simulation of oncological clinical trials.

The NASA Advanced SuperGrid computing facility ran genetic algorithms using the Condor cycle scavenger running on about 350 Sun Microsystems and SGI workstations.
