In the context of heterogeneous networks, like clusters of workstations, the design of programming and execution environments aims to automatically adapt execution to fluctuations that may appear in the execution of distributed and parallel Java applications. ADAJ, Adaptive Distributed Applications in Java, addresses this problem, dealing with both parallelism and distribution features. Ease of programming is achieved through an object and method parallelism paradigm. The trade-off between transparency of such a parallelism expression and efficiency is solved by application redeployment, meant to maintain a good performance level. This is the purpose of the load balancing in ADAJ, a dynamic and transparent tool at the middleware level, which exploits information issued from observation of the application, in order to consider both object activity and communication patterns. Communications generate attraction relations between objects and this article presents the evaluation of the load balancing mechanism for a type of asynchronous applications in which the communication aspect is important.

The Web

Internet technology continues to grow fast and has now become the dominant computing technology in developing software and computing applications. By fully taking advantage of the quick development of the service concept and modeling, Web services technology, as part of Internet technology, has rapidly evolved and made a drastic impact on enterprise integration. A deployed Web based service, relying on a suite of Internet based standard protocols, is self-contained, self-describing, and network-neutral computing component. It can be readily deployed, published, located, and invoked over the heterogeneous networks. This chapter starts with a brief introduction to the concepts of services and enterprise service computing. The Web service’s technical fundamentals are then fully explored. XML, SOAP, WSDL, and UDDI as the core technologies are further explained in great detail. Implementation examples are finally used to demonstrate how the Web services technology can be typically applied in integrating distributed applications across an organization.

Construction Efficiency

Trie is one of the most common data structures for string storage and retrieval. As a fast and efficient implementation of trie, double array (DA) can effectively compress strings to reduce storage spaces. However, this method suffers from the problem of low index construction efficiency. To address this problem, we design a two-level partition (TLP) framework in this paper. We first divide the dataset is into smaller lower-level partitions, and then we merge these partitions into bigger upper-level partitions using a min-heap based greedy merging algorithm (MH-GMerge). TLP has an excellent characteristic of load balancing and can be easily parallelized. We implemented two efficient parallel partitioned DAs based on TLP. Extensive experiments were carried out, and the results showed that the proposed methods can significantly improve the construction efficiency of DA and can achieve a better trade-off between construction and retrieval performance than the existing state-of-the-art methods.
