	Grid network - Wikipedia, the free encyclopedia
		A grid network is a kind of 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.
		In general, when an n-dimensional grid network is connected circularly in more than one dimension, the resulting network topology is a torus, and the network is called "toroidal".

	CCR 711: Network(ed) Rhetorics: Grid Ubiquity
		In his chapter "From Grid to Network," Taylor's objects for study draw mostly on architecture and Fordist/Taylorist efficiency models, those privileging linearity or departing from it toward an antitheses, nonlinearity (the lists do a better job than I have here of explaining the differences).
		I have a lot of questions about the suggestion of a shift from grid to network, and many of them are questions I suspect Taylor answers later in The Moment of Complexity, which means I probably ought to add it in its entirety to the growing list.

	Network World: grid storage facade, The (Site not responding. Last check: 2007-10-08)
		Grid storage refers to two items: a topology for scaling the capacity of network-attached storage (NAS) in response to application requirements, and a technology for enabling and managing a single file system so that it can span an increasing volume of storage.
		Grid storage, in theory attacks these limits by joining NAS heads into highly scalable clusters and by alleviating the constraints of file system address space through the use of an extensible file system.
		Grid storage would be useful to anyone with a large complement of NAS arrays to administer, according to a manager of a national Internet e-mail portal service who asked not to be named.

		Network attached storage requires additional network capacity; it is recommended that this capacity be provided by a separate private or storage area network (SAN).
		Network configuration can be performed in three ways on Red Hat Linux Advanced Server 2.1: manually (not recommended), at installation time (to provide basic hostname and IP information), and using the X Windows-based Network Configuration tool (/usr/sbin/neat) after installation is complete.
		It is recommended that private network addresses be managed using the former method for small clusters (when not connected to the Internet) in order to avoid the complexity of setting a DNS server for a small network.

		Grid computing has been cost-effective for Incyte Genomics.The company moved from a 32-processor Sun E10000 to an Intel-based grid running Platform Computing's software, and Jackson's price/performance calculations show the grid is about 10 times less expensive for the same computer power.
		Grid computing architectures provide advantages in performance and flexibility but there are still issues keeping many companies from leaping too quickly onto the grid bandwagon.

	Exposing the parasitic grid - Americas Network
		Since many unlicensed networks are cooperatives or collectives rather than commercial public networks, this represents a challenge to the whole notion of communications as a commercial utility service.
		The idea of the parasitic grid is popular among hacker discussion groups for fairly obvious reasons and has elicited interest among considerable numbers of individual data professionals in Northern California as well as among the wireless cooperatives themselves, many of whom are eager to free themselves from any dependence whatsoever on the telco incumbent.
		The notion of such an anarchic network is not new, having been advanced by George Gilder for almost 10 years in his book, "After Television," though Gilder believed fiber optics rather than airlinks would form the basis for such a network.

		When the network is as fast as the computer's internal links, the machine disintegrates across the net into a set of special purpose appliances.
		Grid computing concepts were first explored in the 1995 I-WAY experiment, in which high-speed networks were used to connect, for a short time, high-end resources at 17 sites across North America.
		As technologies, networks and business models mature, I expect that it will become commonplace for small and large communities of scientists to create "Science Grids" linking their various resources to support human communication, data access and computation.

		The Grid can be a difficult concept to describe, but it is essentially a means for sharing resources (processing power, databases, radio telescopes...) via a distributed computer network.
		As an example of how network measurements could be used in a Grid environment, we use the case of a Grid file transfer service.
		For the first time, end users will be able to see for themselves what performance they should be expecting from their Grid applications, regardless of what they know (or think they know) about the speed of the network connections used by their site or individual computer.

		A grid is a network of computational research centers whose supercomputer clusters, databases, and specialized programs form a pool of resources that is more powerful and more versatile than that of any single research center, or node, on the network.
		Grid software may well change the way scientists and, eventually, the rest of us interact with computers, according to some academic researchers who work with grid technologies.
		In the lineup as nodes on the grid are the North Carolina Supercomputing Center at Research Triangle Park, Duke University, North Carolina State University, and the University of North Carolina at Chapel Hill.

		One of the main advantage provided by Nodezilla over classical decentralized P2P networks, is the introduction of Persistant file Sharing, where a file is still available to download even if the original "sharer" goes offline, making popular content available 100% of the time at 100% of the client bandwidth, see below for details.
		To achieve this the Nodezilla Network needs of course some room to store the persistent files, this room will be found in a space provided by each Nodezilla user (like 30MB by node).

	Network-Enabled Solvers: A Step Toward Grid-Based Computing
		Two statements have been consistently true in the realm of computer science: (1) the need for computational power is always greater than what is available at any given point, and (2) to access our resources, we always want the simplest, yet most complete and easy to use interface possible.
		The computational grid will be inherently more complex than existing computer systems, and programs designed for grid execution will reflect some of this complexity.
		Making grid resources useful and accessible to scientists and engineers will thus require new software tools that embody major advances in both the theory and the practice of building applications.
