Globus® Toolkit 4: Programming Java Services
The Globus Toolkit is a key technology in Grid Computing, the exciting new computing paradigm that allows users to share processing power, data, storage, and other computing resources across institutional and geographic boundaries. Globus Toolkit 4: Programming Java Services provides an introduction to the latest version of this widely acclaimed toolkit. Based on the popular web-based The Globus Toolkit 4 Programmer's Tutorial, this book far surpasses that document, providing greater detail, quick reference appendices, and many additional examples. If you’re making the leap into Grid Computing using the Globus Toolkit, you’ll want Globus Toolkit 4: Programming Java Services at your side as you take your first steps.

Seite ii - The Grid: Blueprint for a New Computing Infrastructure Edited by Ian Foster and Carl Kesselman Parallel Computer Architecture: A Hardware/Software Approach David E.
Seite 6 - A grid is a system that: 1 . coordinates resources that are not subject to centralized control. . . 2. . . .using standard, open, general-purpose protocols and interfaces. . . 3. . . .to deliver nontrivial qualities of service" Let's take a closer look at the first two points: 1.
Seite 26 - SOAP request has been deserialized, the server stub invokes the service implementation, which then carries out the work it has been asked to do. 4. The result of the requested operation is handed to the server stub, which will turn it into a SOAP response. 5. The SOAP response is sent over a network using the HTTP protocol. The client stub receives the SOAP response and turns it into something the client application can understand. 6.
Seite 30 - Fortunately, it's a problem with a very simple solution: simply keep the Web service and the state information completely separate. Instead of putting the state in the Web service (thus making it stateful, which is generally regarded as a bad thing) we will keep it in a separate entity called a resource, which will store all the state information. Each resource will have a unique...
Seite 14 - OGSA is an informational specification that aims to define a common, standard, and 184 open architecture for grid-based applications. The goal of OGSA is to standardize almost all the services that a grid application may use, for example job and resource management services, communications, and security. OGSA specifies a service-oriented architecture (SOA) for the grid that realizes a model of a computing system as a set of distributed computing patterns realized...
Seite 7 - ... a wide variety of operating systems and architectures, and somehow make them collaborate to solve computational tasks. The only way to do this is by using "standard, open, generalpurpose protocols and interfaces" that provide a "common language" that everyone on the Grid can understand.
