  The MathWorks - Distributed Computing Toolbox - Perform distributed and parallel computations
By distributing the tasks across three servers, we reduced the simulation time from 6 hours to 1.2 hours.
Distributed Computing Toolbox enables you to solve computationally and data-intensive problems using MATLAB and Simulink in a multiprocessor computing environment.
These processors can reside in one multiprocessor computer or, when the toolbox is used with MATLAB Distributed Computing Engine, on a computer cluster.

  Distributed computing - Wikipedia, the free encyclopedia
Distributed computing is decentralised and parallel computing, using two or more computers communicating over a network to accomplish a common objective or task.
Distributed computing differs from cluster computing in that computers in a distributed computing environment are typically not exclusively running "group" tasks, whereas clustered computers are usually much more tightly coupled.

 Cosm - Chapter 2 - Overview of Distributed Computing
Distributed computing is simply applying the two old sayings to the realm of computer resources.
One of the benefits that a distributed system has is that it can continue to operate even if some of its parts are missing, this resulting in much better reliability of the system than a single computer could ever provide.
A distributed operating system can be created by merging these functions into the traditional operating system, or as another abstraction layer on top of the traditional operating system and network operating system.

 Distributed & Grid Computing
Distributed computing: Increasingly known as grid computing, this approach connects a wide variety of computer types and computing resources, such as storage area networks, to create vast "virtual" reservoirs of computers serving geographically widely separated users.
Grid Computing can be defined as applying resources from many computers in a network to a single problem, usually one that requires a large number of processing cycles or access to large amounts of data.
The whole area of distributed computing is a hot bed of significant development that is expected to generate amazing advances in the next few years.

 A primer on distributed computing.
A popular solution is the "distributed computing" model, where the task is split up into smaller chunks and performed by the many computers owned by the general public.
Distributed computing works by splitting up the larger task into smaller chunks which can be performed at the same time independently of each other.
Distributed computing is sold on the idea that you can continue working and the client will do its thing in the background and the user will not notice anything different.

 Distributed Computing
Distributed computing is a science which solves a large problem by giving small parts of the problem to many computers to solve and then combining the solutions for the parts into a solution for the problem.
These projects are so large, and require so much computing power to solve, that they would be impossible for any one computer or person to solve in a reasonable amount of time.

 GRIDtoday: AN OVERVIEW OF DISTRIBUTED GRID COMPUTING
Distributed grid computing -- which harnesses the power of multiple CPUs -- grew out of scientists’ and academics' needs for processing power, but it is rapidly developing commercial applications.
The promise of grid computing is you can start being much more dynamic with resource provision at the back end, and then at the front end you make it possible for people to dynamically acquire resources from different locations rather than rely on the static resources they have," says Foster.
The focus of distributed computing has shifted from parallelism to the sharing of equipment for computing, he suggests, for example, to take advantage of processing time outside normal hours.

A type of computing in which different components and objects comprising an application can be located on different computers connected to a network.

 Stanford gives distributed computing an A | CNET News.com
Distributed computing involves spreading computing tasks across hundreds or thousands of computers on the Internet or private networks that would otherwise be sitting idle.
The idea of tapping spare processing power from ordinary PCs has seized the imagination of the computing industry, luring thousands of volunteers into donating their spare CPU cycles to the search for extraterrestrial life and to the battle against diseases such as cancer.
And though distributed computing projects have had some success when it comes to mathematical challenges--one group found the largest prime numbers, while another group deciphered a message encoded with RSA Security's RC5-64 encryption algorithm--the Stanford experiment illustrates that distributed computing can be applied to problems scientists encounter in the laboratory.

 Note on Distributed Computing, A
We argue that objects that interact in a distributed system need to be dealt with in ways that are intrinsically different from objects that interact in a single address space.
These differences are required because distributed systems require that the programmer be aware of latency, have a different model of memory access, and take into account issues of concurrency and partial failure.
We look at a number of distributed systems that have attempted to paper over the distinction between local and remote objects, and show that such systems fail to support basic requirements of robustness and reliability.
