This volume provides a comprehensive analysis of the concepts, designs and implementations of one virtual computing environment. The work features the Adaptive Distributed Virtual Computing Environment (ADViCE), which was developed to create an open programmable computing environment that supports the development, execution, visualization, and experimentation with large-scale parallel and distributed applications. ADViCE's objective is an important step towards the ultimate goal of implementing a real virtual computing environment that provides ubiquitous open computing services in an analogous way to the services offered by telephone and electrical (utility) companies. The material includes coverage of computing technology, metacomputing systems, scheduling algorithms, experimental results, prediction algorithms for real-time execution time with/without tuning functions, and more. This book is considered a starting reference work for researchers in parallel and distributed computing, supercomputing and networking professionals.

The explosive growth of Internet-based applications and the proliferation of networking technologies have transformed not only the computer science and engineering fields but also has affected the areas of computational science and commercial Internet applications. This has provided researchers with an opportunity to explore new Internet-oriented software technologies designed to expand research and application opportunities in multimedia, commerce, and the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - provide increased programmability to bring new services to Internet-based applications. The chapters in this volume are based on presentations at the Second Annual Workshop on Active Middleware Services. The volume draws on research results in active networks, mobile and intelligent agents, software tools for high-performance distributed computing, network operating systems, and application programming models and environments.The text should be appropriate for engineers and researchers in the areas of network centric computing and distributed information systems, as well as for application and tool developers and users of information systems.

The complexity of modern computer networks and systems, combined with the extremely dynamic environments in which they operate, is beginning to outpace our ability to manage them. Taking yet another page from the biomimetics playbook, the autonomic computing paradigm mimics the human autonomic nervous system to free system developers and administrators from performing and overseeing low-level tasks. Surveying the current path toward this paradigm, Autonomic Computing: Concepts, Infrastructure, and Applications offers a comprehensive overview of state-of-the-art research and implementations in this emerging area.This book begins by introducing the concepts and requirements of autonomic computing and exploring the architectures required to implement such a system. The focus then shifts to the approaches and infrastructures, including control-based and recipe-based concepts, followed by enabling systems, technologies, and services proposed for achieving a set of "self-*" properties, including self-configuration, self-healing, self-optimization, and self-protection. In the final section, examples of real-world implementations reflect the potential of emerging autonomic systems, such as dynamic server allocation and runtime reconfiguration and repair.Collecting cutting-edge work and perspectives from leading experts, Autonomic Computing: Concepts, Infrastructure, and Applications reveals the progress made and outlines the future challenges still facing this exciting and dynamic field.

The papers in this volume were presented at the Second Annual Work­ shop on Active Middleware Services and were selected for inclusion here by the Editors. The AMS workshop was organized with support from both the National Science Foundation and the CAT center at the Uni­ versity of Arizona, and was held in Pittsburgh, Pennsylvania, on August 1, 2000, in conjunction with the 9th IEEE International Symposium on High Performance Distributed Computing (HPDC-9). The explosive growth of Internet-based applications and the prolifer­ ation of networking technologies has been transforming most areas of computer science and engineering as well as computational science and commercial application areas. This opens an outstanding opportunity to explore new, Internet-oriented software technologies that will open new research and application opportunities not only for the multimedia and commercial world, but also for the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - allow increased programmability to enable bring­ ing new services to Internet based applications. The AMS workshop presented research results and working papers in the areas of active net­ works, mobile and intelligent agents, software tools for high performance distributed computing, network operating systems, and application pro­ gramming models and environments. The success of an endeavor such as this depends on the contributions of many individuals. We would like to thank Dr. Frederica Darema and the NSF for sponsoring the workshop.
