This book is on dependence concepts and general methods for dependence testing. Here, dependence means data dependence and the tests are compile-time tests. We felt the time was ripe to create a solid theory of the subject, to provide the research community with a uniform conceptual framework in which things fit together nicely. How successful we have been in meeting these goals, of course, remains to be seen. We do not try to include all the minute details that are known, nor do we deal with clever tricks that all good programmers would want to use. We do try to convince the reader that there is a mathematical basis consisting of theories of bounds of linear functions and linear diophantine equations, that levels and direction vectors are concepts that arise rather natu rally, that different dependence tests are really special cases of some general tests, and so on. Some mathematical maturity is needed for a good understand ing of the book: mainly calculus and linear algebra. We have cov ered diophantine equations rather thoroughly and given a descrip of some matrix theory ideas that are not very widely known. tion A reader familiar with linear programming would quickly recog nize several concepts. We have learned a great deal from the works of M. Wolfe, and K. Kennedy and R. Allen. Wolfe's Ph. D. thesis at the University of Illinois and Kennedy & Allen's paper on vectorization of Fortran programs are still very useful sources on this subject."

This book is the result of the 11 th International Conference on Information Systems Development -Methods and Tools, Theory and Practice, held in Riga, Latvia, September 12-14,2002. The purpose of this conference was to address issues facing academia and industry when specifying, developing, managing, reengineering and improving information systems. Recently many new concepts and approaches have emerged in the Information Systems Development (ISD) field. Various theories, methodologies, methods and tools available to system developers also created new problems, such as choosing the most effective approach for a specific task, or solving problems of advanced technology integration into information systems. This conference provides a meeting place for ISD researchers and practitioners from Eastern and Western Europe as well as from other parts of the world. Main objectives of this conference are to share scientific knowledge and interests and to establish strong professional ties among the participants. The 11th International Conference on Information Systems Development (ISD'02) continues the tradition started with the first Polish-Scandinavian Seminar on Current Trends in Information Systems Development Methodologies, held in Gdansk, Poland in 1988. Through the years this Seminar has evolved into the International Conference on Information Systems Development. ISD'02 is the first ISD conference held in Eastern Europe, namely, in Latvia, one of the three Baltic countries.

Concurrent systems abound in human experience but their fully adequate conceptualization as yet eludes our most able thinkers. The COSY (ConcurrentSystem) notation and theory was developed in the last decade as one of a number of mathematical approaches for conceptualizing and analyzing concurrent and reactive systems. The COSY approach extends theconventional notions of grammar and automaton from formal language and automata theory to collections of "synchronized" grammars and automata, permitting system specification and analysis of "true" concurrency without reduction to non-determinism. COSY theory is developed to a great level of detail and constitutes the first uniform and self-contained presentationof all results about COSY published in the past, as well as including many new results. COSY theory is used to analyze a sufficient number of typical problems involving concurrency, synchronization and scheduling, to allow the reader to apply the techniques presented tosimilar problems. The COSY model is also related to many alternative models of concurrency, particularly Petri Nets, Communicating Sequential Processes and the Calculus of Communicating Systems.

PC viruses are not necessarily a major disaster despite what is sometimes written about them. But a virus infection is at the very least a nuisance, and potentially can lead to loss of data. Quite often it is the user's panic reaction to discovering a virus infection that does more than the virus itself. This book demystifies PC viruses, providing clear, accurate information about this relatively new PC problem. It enables managers and PC users to formulate an appropriate response; adequate for prevention and cure, but not `over the top'. Over 100 PC viruses and variants are documented in detail. You are told how to recognise each one, what it does, how it copies itself, and how to get rid of it. Other useful and relevant technical information is also provided. Strategies for dealing with potential and actual virus outbreaks are described for business, academic and other environments, with the emphasis on sensible but not unreasonable precautions. All users of IBM PC or compatible computers - from single machines to major LAN's - will find this book invaluable. All that is required is a working knowledge of DOS. Dr. Alan Solomon has been conducting primary research into PC viruses since they first appeared, and has developed the best-selling virus protection software Dr. Solomon's Anti-Virus Toolkit.

Real-time computing systems are vital to a wide range of applications. For example, they are used in the control of nuclear reactors and automated manufacturing facilities, in controlling and tracking air traffic, and in communication systems. In recent years, real-time systems have also grown larger and become more critical. For instance, advanced aircraft such as the space shuttle must depend heavily on computer sys tems Carlow 84]. The centralized control of manufacturing facilities and assembly plants operated by robots are other examples at the heart of which lie embedded real-time systems. Military defense systems deployed in the air, on the ocean surface, land and underwater, have also been increasingly relying upon real-time systems for monitoring and operational safety purposes, and for retaliatory and containment measures. In telecommunications and in multi-media applications, real time characteristics are essential to maintain the integrity of transmitted data, audio and video signals. Many of these systems control, monitor or perform critical operations, and must respond quickly to emergency events in a wide range of embedded applications. They are therefore required to process tasks with stringent timing requirements and must perform these tasks in a way that these timing requirements are guaranteed to be met. Real-time scheduling al gorithms attempt to ensure that system timing behavior meets its specifications, but typically assume that tasks do not share logical or physical resources. Since resource-sharing cannot be eliminated, synchronization primitives must be used to ensure that resource consis tency constraints are not violated."

In conjunction with the 1993 International Conference on Logic Programming (ICLP'93), held in Budapest Hungary, two workshops were held concerning the implementations of logic programming systems: Practical Implementations and Sys- tems Experience in Logic Programming Systems, and Concurrent, Distributed, and Parallel Implementations of Logic Programming Systems. This collection presents 16 research papers in the area of the implementation of logic programming systems. The two workshops aimed to bring together sys- tems implementors for discussing real problems coming from their direct experience, therefore these papers have a special emphasis on practice rather than on theory. This book will be of immediate interest to practitioners who seek understanding of how to efficiently manage memory, generate fast code, perform sophisticated static analyses, and design high-performance runtime features. A major theme, throughout the papers, is how to effectively leverage host imple- mentation systems and technologies to implement target systems. Debray discusses implementing Janus in SICStus Prolog by exploiting the delay primitive, which is fur- ther expounded by Meier in his discussion of various ECRC systems implementations of delay primitives. Hausman discusses implementing Erlang in C, and Czajkowski and Zielinski discuss embedding Linda primitives in Strand. Denti et ai. discuss implementing object-oriented logic programs within SICStus Prolog, a theme also explored and compared to a WAM-based implementation by Bugliesi and Nardiello.

In this international collection of papers there is a wealth of knowledge on artificial intelligence (AI) and cognitive science (CS) techniques applied to the problem of providing help systems mainly for the UNIX operating system. The research described here involves the representation of technical computer concepts, but also the representation of how users conceptualise such concepts. The collection looks at computational models and systems such as UC, Yucca, and OSCON programmed in languages such as Lisp, Prolog, OPS-5, and C which have been developed to provide UNIX help. These systems range from being menu-based to ones with natural language interfaces, some providing active help, intervening when they believe the user to have misconceptions, and some based on empirical studies of what users actually do while using UNIX. Further papers investigate planning and knowledge representation where the focus is on discovering what the user wants to do, and figuring out a way to do it, as well as representing the knowledge needed to do so. There is a significant focus on natural language dialogue where consultation systems can become active, incorporating user modfelling, natural language generation and plan recognition, modelling metaphors, and users' mistaken beliefs. Much can be learned from seeing how AI and CS techniques can be investigated in depth while being applied to a real test-bed domain such as help on UNIX.

This volume contains a selection of papers that focus on the state-of the-art in formal specification and verification of real-time computing systems. Preliminary versions of these papers were presented at a workshop on the foundations of real-time computing sponsored by the Office of Naval Research in October, 1990 in Washington, D. C. A companion volume by the title Foundations of Real-Time Computing: Scheduling and Resource Management complements this hook by addressing many of the recently devised techniques and approaches for scheduling tasks and managing resources in real-time systems. Together, these two texts provide a comprehensive snapshot of current insights into the process of designing and building real time computing systems on a scientific basis. The notion of real-time system has alternative interpretations, not all of which are intended usages in this collection of papers. Different communities of researchers variously use the term real-time to refer to either very fast computing, or immediate on-line data acquisition, or deadline-driven computing. This text is concerned with the formal specification and verification of computer software and systems whose correct performance is dependent on carefully orchestrated interactions with time, e. g., meeting deadlines and synchronizing with clocks. Such systems have been enabled for a rapidly increasing set of diverse end-uses by the unremitting advances in computing power per constant-dollar cost and per constant-unit-volume of space. End use applications of real-time computers span a spectrum that includes transportation systems, robotics and manufacturing, aerospace and defense, industrial process control, and telecommunications."

This book covers the entire spectrum of multicasting on the Internet from link- to application-layer issues, including multicasting in broadcast and non-broadcast links, multicast routing, reliable and real-time multicast transport, group membership and total ordering in multicast groups. In-depth consideration is given to describing IP multicast routing protocols, such as, DVMRP, MOSPF, PIM and CBT, quality of service issues in network-layer using RSVP and ST-2, as well as the relationship between ATM and IP multicast. These discussions include coverage of key concepts using illustrative diagrams and various real-world applications. The protocols and the architecture of MBone are described, real-time multicast transport issues are addressed and various reliable multicast transport protocols are compared both conceptually and analytically. Also included is a discussion of video multicast and other cutting-edge research on multicast with an assessment of their potential impact on future internetworks.Multicasting on the Internet and Its Applications is an invaluable reference work for networking professionals and researchers, network software developers, information technology managers and graduate students.

Operating Systems and Services brings together in one place important contributions and up-to-date research results in this fast moving area. Operating Systems and Services serves as an excellent reference, providing insight into some of the most challenging research issues in the field.

A growing concern of mine has been the unrealistic expectations for new computer-related technologies introduced into all kinds of organizations. Unrealistic expectations lead to disappointment, and a schizophrenic approach to the introduction of new technologies. The UNIX and real-time UNIX operating system technologies are major examples of emerging technologies with great potential benefits but unrealistic expectations. Users want to use UNIX as a common operating system throughout large segments of their organizations. A common operating system would decrease software costs by helping to provide portability and interoperability between computer systems in today's multivendor environments. Users would be able to more easily purchase new equipment and technologies and cost-effectively reuse their applications. And they could more easily connect heterogeneous equipment in different departments without having to constantly write and rewrite interfaces. On the other hand, many users in various organizations do not understand the ramifications of general-purpose versus real-time UNIX. Users tend to think of "real-time" as a way to handle exotic heart-monitoring or robotics systems. Then these users use UNIX for transaction processing and office applications and complain about its performance, robustness, and reliability. Unfortunately, the users don't realize that real-time capabilities added to UNIX can provide better performance, robustness and reliability for these non-real-time applications. Many other vendors and users do realize this, however. There are indications even now that general-purpose UNIX will go away as a separate entity. It will be replaced by a real-time UNIX. General-purpose UNIX will exist only as a subset of real-time UNIX.

In this work, the unique power measurement capabilities of the Cray XT architecture were exploited to gain an understanding of power and energy use, and the effects of tuning both CPU and network bandwidth. Modifications were made to deterministically halt cores when idle. Additionally, capabilities were added to alter operating P-state. At the application level, an understanding of the power requirements of a range of important DOE/NNSA production scientific computing applications running at large scale is gained by simultaneously collecting current and voltage measurements on the hosting nodes. The effects of both CPU and network bandwidth tuning are examined, and energy savings opportunities without impact on run-time performance are demonstrated. This research suggests that next-generation large-scale platforms should not only approach CPU frequency scaling differently, but could also benefit from the capability to tune other platform components to achieve more energy-efficient performance.
