“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 ...
While the term has been in use since the mid to late 1990s [2] the growth of cloud computing and Cisco's evangelism of unified data center fabrics followed by unified computing (an evolutionary data center architecture whereby blade servers are integrated or unified with supporting network and storage infrastructure) starting March 2009 has renewed interest in the technology.
The US National Institute of Standards and Technology (NIST) defines infrastructure as a service as: [3]. The capability provided to the consumer is provision processing, storage, networks, as well as other fundamental computing resources where the consumer is able to deploy & run arbitrary software, which can include operating systems and applications.
The Grid Laboratory Uniform Environment (GLUE), is an information model, similar to a database schema, for a uniform representation of grid computing resources. It was originally developed as part of the Enabling Grids for E-sciencE (EGEE) project in Europe, which had worked on a grid information system using tools such as the Globus Toolkit ...
In grid computing, a virtual organization (VO) refers to a dynamic set of individuals or institutions defined around a set of resource-sharing rules and conditions. All these virtual organizations share some commonality among them, including common concerns and requirements, but may vary in size, scope, duration, sociology, and structure.
Since technology is not the end goal of education, but rather a means by which it can be accomplished, educators must have a good grasp of the technology and its advantages and disadvantages. Teacher training aims for the effective integration of classroom technology. [244] Teacher training in Naura
The concept of OGSA is derived from work presented in the 2002 Globus Alliance paper "The Physiology of the Grid" by Ian Foster, Carl Kesselman, Jeffrey M. Nick, and Steven Tuecke. [2] It was developed by GGF working groups which resulted in a document, entitled The Open Grid Services Architecture, Version 1.5 in 2006. [3]
GOS was designed to deal with long-distance, cross-domain and single-image file operations, which is typical in Grid environments. GOS behaves like a file server via the file-based GOS-FS protocol to any entity on the grid. Similar to GridFTP, GOS-FS integrates a parallel stream engine and Grid Security Infrastructure (GSI).
