Flash-Gridding with Java Technology: Using Project Glassfish
TS-3714

One of the major challenges in grid computing is dynamic configuration of the grid. The Java technology environment is uniquely suited to meet this challenge, because it offers the ability to combine mobile code and industry-standard APIs with a powerful security model. These capabilities make it possible to build scalable grid computing systems that require minimal centralized configuration infrastructure and simplify on-the-fly deployment and removal of grid assets. This session discusses the ComputeCycles project, an effort to build an open source compute grid around these capabilities of Java technology.

ComputeCycles is being constructed on a framework of web services deployed into the Project Glassfish^SM application server. The main web service hosts dynamically configured Jiniâ?  services, which form the mechanism for deploying mobile code into the grid in a standard master/worker design pattern.

• Hosting JavaSpaces technology to provide secure shared memory between grid nodes.
• Managing resource allocation to grid users.
• Providing dynamic configuration to service nodes in the form of Groovy classes.
• Providing dynamic reprovisioning of grid nodes to deal with changing loads.

The design and architecture of the ComputeCycles environment are discussed in detail, and examples of its use are provided.
