Overview[ edit ] Grid computing combines computers from multiple administrative domains to reach a common goal,  to solve a single task, and may then disappear just as quickly. The size of a grid may vary from small—confined to a network of computer workstations within a corporation, for example—to large, public collaborations across many companies and networks.
This technology has been applied to computationally intensive scientific, mathematical, and academic problems through volunteer computingand it is used in commercial enterprises for such diverse applications as drug discoveryeconomic forecastingseismic analysisand back office data processing in support for e-commerce and Web services.
Coordinating applications on Grids can be a complex task, especially when coordinating the flow of information across distributed computing resources.
Grid workflow systems have been developed as a specialized form of a workflow management system designed specifically to compose and execute a series of computational or data manipulation steps, or a workflow, in the Grid context. The primary performance disadvantage is that the various processors and local storage areas do not have high-speed connections.
This arrangement is thus well-suited to applications in which multiple parallel computations can take place independently, without the need to communicate intermediate results between processors. It can be costly and difficult to write programs that can run in the environment of a supercomputer, which may have a custom operating system, or require the program to address concurrency issues.
This makes it possible to write and debug on a single conventional machine and eliminates complications due to multiple instances of the same program running in the same shared memory and storage space at the same time.
Design considerations and variations[ edit ] This section does not cite any sources. Please help improve this section by adding citations to reliable sources.
Unsourced material may be challenged and removed. December Learn how and when to remove this template message One feature of distributed grids is that they can be formed from computing resources belonging to one or more multiple individuals or organizations known as multiple administrative domains.
This can facilitate commercial transactions, as in utility computingor make it easier to assemble volunteer computing networks.
One disadvantage of this feature is that the computers which are actually performing the calculations might not be entirely trustworthy. The designers of the system must thus introduce measures to prevent malfunctions or malicious participants from producing false, misleading, or erroneous results, and from using the system as an attack vector.
This often involves assigning work randomly to different nodes presumably with different owners and checking that at least two different nodes report the same answer for a given work unit.
Discrepancies would identify malfunctioning and malicious nodes. However, due to the lack of central control over the hardware, there is no way to guarantee that nodes will not drop out of the network at random times.
Some nodes like laptops or dial-up Internet customers may also be available for computation but not network communications for unpredictable periods. These variations can be accommodated by assigning large work units thus reducing the need for continuous network connectivity and reassigning work units when a given node fails to report its results in expected time.
The impacts of trust and availability on performance and development difficulty can influence the choice of whether to deploy onto a dedicated cluster, to idle machines internal to the developing organization, or to an open external network of volunteers or contractors.
In many cases, the participating nodes must trust the central system not to abuse the access that is being granted, by interfering with the operation of other programs, mangling stored information, transmitting private data, or creating new security holes.
Public systems or those crossing administrative domains including different departments in the same organization often result in the need to run on heterogeneous systems, using different operating systems and hardware architectures. With many languages, there is a trade-off between investment in software development and the number of platforms that can be supported and thus the size of the resulting network.
Cross-platform languages can reduce the need to make this tradeoff, though potentially at the expense of high performance on any given node due to run-time interpretation or lack of optimization for the particular platform.
Various middleware projects have created generic infrastructure to allow diverse scientific and commercial projects to harness a particular associated grid or for the purpose of setting up new grids.
BOINC is a common one for various academic projects seeking public volunteers; more are listed at the end of the article. In fact, the middleware can be seen as a layer between the hardware and the software. On top of the middleware, a number of technical areas have to be considered, and these may or may not be middleware independent.
These technical areas may be taken care of in a commercial solution, though the cutting edge of each area is often found within specific research projects examining the field. Market segmentation of the grid computing market[ edit ] For the segmentation of the grid computing market, two perspectives need to be considered: The provider side[ edit ] The overall grid market comprises several specific markets.
These are the grid middleware market, the market for grid-enabled applications, the utility computing market, and the software-as-a-service SaaS market.
Grid middleware is a specific software product, which enables the sharing of heterogeneous resources, and Virtual Organizations. It is installed and integrated into the existing infrastructure of the involved company or companies and provides a special layer placed among the heterogeneous infrastructure and the specific user applications.
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-enabled applications are specific software applications that can utilize grid infrastructure.
This is made possible by the use of grid middleware, as pointed out above. Providers of SaaS do not necessarily own the computing resources themselves, which are required to run their SaaS.
Therefore, SaaS providers may draw upon the utility computing market.
The utility computing market provides computing resources for SaaS providers.Grid computing is the use of widely distributed computer resources to reach a common goal. The grid can be thought of as a distributed system with non-interactive workloads that involve a large number of files.
Many volunteer computing projects, such as BOINC, use the CPU scavenging model.
