“Distributed” or “grid” computing in general is a special type of parallel computing that relies on complete computers (with onboard CPUs, storage, power supplies, network interfaces, etc.) connected to a network (private, public or the Internet) by a conventional network interface producing commodity hardware, compared to the lower efficiency of designing and constructing a small ...
Open Grid Services Architecture (OGSA) describes a service-oriented architecture for a grid computing environment for business and scientific use. It was developed within the Open Grid Forum , which was called the Global Grid Forum (GGF) at the time, around 2002 to 2006.
Layout of a grid low-voltage network. A grid network is a computer network consisting of a number of computer systems connected in a grid topology. In a regular grid topology, each node in the network is connected with two neighbors along one or more dimensions. If the network is one-dimensional, and the chain of nodes is connected to form a ...
Example architecture of a geographically disperse computing system connecting many nodes over a network. Grid computing uses a large number of computers in distributed, diverse administrative domains. It is an opportunistic approach which uses resources whenever they are available. [10] An example is BOINC a volunteer-based, opportunistic grid ...
gLite (pronounced "gee-lite") is a middleware computer software project for grid computing used by the CERN LHC experiments and other scientific domains. It was implemented by collaborative efforts of more than 80 people in 12 different academic and industrial research centers in Europe. gLite provides a framework for building applications tapping into distributed computing and storage ...
Grid computing is the most distributed form of parallel computing. It makes use of computers communicating over the Internet to work on a given problem. Because of the low bandwidth and extremely high latency available on the Internet, distributed computing typically deals only with embarrassingly parallel problems.
The other extreme is where a computer job uses one or few nodes, and needs little or no inter-node communication, approaching grid computing. In a Beowulf cluster , the application programs never see the computational nodes (also called slave computers) but only interact with the "Master" which is a specific computer handling the scheduling and ...
The smart grid is an enhancement of the 20th century electrical grid, using two-way communications and distributed so-called intelligent devices. [1]
