Book Description
Abstract: "The paper presents an improved method for semi- automatic bug localization, by extending the Generalized Algorithmic Debugging Technique, GADT [Fritzson, et.al-91], which uses declarative assertions about program units such as procedures, with operational assertions about program behavior. For example, functional properties are best expressed through declarative assertions about procedure units, whereas order-dependent properties such as race conditions in parallel processing, or sequencing constraints in general, are more easily expressed using operational semantics. A powerful assertion language, called FORMAN, has been developed to this end. Such assertions can be collected into assertion-libraries, which can greatly increase the degree of automation in bug localization. The long-range goal of this work is a semi-automatic debugging and testing system which can be used during large- scale program development of non-trivial programs. The need for such automated debugging support will increase as applications on parallel architectures become more prevalent, since such programs are both harder to write and to debug, partly because of non-sequential execution semantics. Our previously developed GADT method was the first declarative algorithmic debugging technique for procedural imperative languages with side-effects. GADT is generally applicable to procedural languages, and is not dependent on any ad hoc assumptions regarding the subject program. The original form of algorithmic debugging, introduced by Shapiro [Shapiro-82], is however limited to small Prolog programs without side-effects. Another drawback of the original method is the large number of interactions with the user during bug localization. To our knowledge, the extended GADT presented here is the first method which uses powerful operational assertions in algorithmic debugging. In addition to providing support for local-level bug localization within procedures (which is not handled well by basic algorithmic debugging), the operational assertions reduce the number of irrelevant questions to the programmer during bug localization, thus further improving bug localization. Previously, we have enhanced the bug localization properties of GADT, using lookup in a category partition testing database. In addition, we use program slicing, a data flow analysis technique, to dynamically compute which parts of the program are relevant for the search. A prototype of the GADT has been implemented in Pascal, supporting debugging in a subset of Pascal. An interpreter of FORMAN assertions has also been implemented in Pascal. During bug localization, both types of assertions are evaluated on execution traces."

Book Description
Debugging has always been a costly part of software development, and many attempts have been made to provide automatic computer support for this task.Automated debugging has seen major develoments over the last decade. Onesuccessful development is algorithmic debugging, which originated in logic programming but was later generalized to concurrent, imperative, and lazy functional languages. Important advances have also been made in knowledge-based program debugging, and in approaches to automated debugging based on static and dynamic program slicing based on dataflow and dependence analysis technology. This is the first collected volume of papers on automated debugging and presents latest developments, tutorial papers, and surveys.

Book Description
The field of parallel and distributed computing is undergoing changes at a breathtaking pace. Networked computers are now omnipresent in virtually every application, from games to sophisticated space missions. The increasing complexity, heterogeneity, largeness, and dynamism of the emerging pervasive environments and associated applications are challenging the advancement of the parallel and distributed computing paradigm. Many novel infrastructures have been or are being created to provide the necessary computational fabric for realising parallel and distributed applications from diverse domains. New models and tools are also being proposed to evaluate and predict the quality of these complicated parallel and distributed systems. Current and recent past efforts, made to provide the infrastructures and models for such applications, have addressed many underlying complex problems and have thus resulted in new tools and paradigms for effectively realising parallel and distributed systems. This book showcases these novel tools and approaches with inputs from relevant experts.

Book Description
Current IT developments like component-based development and Web services have emerged as effective ways of building complex enterprise-scale information systems and providing enterprise application integration. To aid this process, platforms such as .NET and WebSphere have become standards in web-based systems development. However, there are still a lot of issues that need to be addressed before service-oriented software engineering (SOSE) becomes a prominent and widely accepted paradigm for enterprise information systems development and integration. This book provides a comprehensive view of SOSE through a number of different perspectives. Some of those perspectives include: service-based concepts, modeling and documentation, service discovery and composition, service-oriented architecture, model-driven development of service-oriented applications, service security and service-orientation in mobile settings. The book provides readers with an in-depth knowledge of the main challenges and practices in the exciting, new world of service-oriented software engineering. Addressing both technical and organizational aspects of this new field, it offers a balance making it valuable to a variety of readers, including IT architects, developers, managers, and analysts.

Book Description
Declarative languages have traditionally been regarded by the mainstream c- puting community as too impractical to be put to practical use. At the same time, traditionalconferencesdevotedto declarativelanguagesdo not haveissues related to practice as their central focus. Thus, there are few forums devoted to discussion of practical aspects and implications of newly discovered results and techniques related to declarative languages. The goal of the First International Workshop on Practical Aspects of Declarative Languages (PADL) is to bring together researchers,practitioners and implementors of declarative languages to discuss practical issues and practical implications of their research results. The workshop was held in San Antonio, Texas, during January 18-19, 1999. This volume contains its proceedings. Fifty three papers were submitted in response to the call for papers. These papers were written by authors belonging to twenty one countries from six c- tinents. Each paper was assigned to at least two referees for reviewing. Twenty four papers were nally selected for presentation at the workshop. Many good papers could not be included due to the limited duration of the workshop. The workshop included invited talks by Mark Hayden of DEC/Compaq Systems - search Center, speaking on \Experiences Building Distributed Systems in ML," and Mark Wallace of Imperial College Center for Planning And Resource C- trol (IC-PARC), speaking on \ECLiPSe: Declarative Specic ation and Scalable Implementation.

Book Description
The ASE conference is the major conference for theory and practice concerned with automating the software development process. Formerly known as Knowledge-Based Software Engineering (KBSE), the conference expanded in order to reach out to other scientific communities concerned with the automation aspects of formal methods, software process, human-computer interaction, requirements engineering, reverse engineering, testing and verification and validation, while still including an active artificial intelligence and knowledge-based research focus.
