Perhaps the best way to describe what Grid Computing is is to describe what is for now its best best known application.

The SETI@Home project was developed to solve a problem: the project, which looks for signs of extraterrestrial intelligence, had terrabytes of information, but not enough computing power to analyze it in any reasonable amount of time. The solution was to find a way to harness the unused computing power of millions of computers around the world. Users downloaded a screensaver, which would download segments of data, analyze them, and send back the results before requesting a new segment.

Although the project didn't use the open source systems we're going to talk about in a moment, it does demonstrate the basic concept of a Grid system. It's got a central core system that coordinates and communicates with remote systems to solve a particular problem.

The general idea of distributing the work over multiple machines has been around for decades, but most recently we've seen the emergence of the Open Grid Service Infrastructure (OGSI), wihch enables different systems to interoperate. Although early versions of the Grid were not Web Service based, OGSI is a series of WSDL specifications that defines various operations and behaviors related to a grid-based system.

More recently, Grid has led to the creation of the Web Services Resource Framework, a set of specifications that assist in the allocation of work between various systems. WSRF consists of six documents. The Globus Alliance, which created the Globus Toolkit, a collection of software packages that enable application developers to create their own grid, describes them as follows:

  • WS-ResourceLifetime defines mechanisms for WS-Resource destruction, including message exchanges that allow a requestor to destroy a resource, either immediately or by using a time-based scheduled resource termination mechanism.
  • WS-ResourceProperties defines how the type definition of a WS-Resource can be associated with the interface description of a Web service, and message exchanges for retrieving, changing, and deleting WS-Resource properties.
  • WS-Notification defines mechanisms for event subscription and notification using a topic-based publish/subscribe pattern.
  • WS-RenewableReferences defines a conventional decoration of a WS-Addressing endpoint reference with policy information needed to retrieve an updated version of an endpoint reference when it becomes invalid.
  • WS-ServiceGroup defines an interface to heterogeneous by-reference collections of Web services.
  • WS-BaseFaults defines a base fault XML type for use when returning faults in a Web services message exchange.

In the coming weeks, we'll look at various implementations and at creating your own Grid system. Check out the resources for a head start.
