Community Informatics is a developing field which brings together understandings about the interaction of communities and information and communication technologies from fields as diverse as Management and Information Systems, Library and Information Sciences, Community Development, Sociology, or Social and Community Welfare. A key assumption of community informatics is that technologies can be used for positive social change and development, particularly with disadvantaged communities or communities that hitherto, have not had a public voice. The volume brings together international perspectives around defining and debating the idea of community memory which, as Alex Byrne, President of the International Federation of Library Associations and Institutions observed in his splendid and wide-ranging Introduction: "community memories are multilayered, changeable, conflicting and contested", and the multilayering, changeability and contest between different players provide fertile theoretical and practical ground for Community Informatics and its interdisciplinary cousins. "Community Informatics is an emerging new multi-disciplinary approach to the study of the intersection of communities and Information and Communication Technologies. This volume contains significant contributions from international practitioners and researchers in the fields of archives, record-keeping, community knowledge management, emerging information and communication technologies, history, community development-virtual as well as real-and Community Informatics as a growing discipline. The content of the book is a unique contribution in the field. The volume will be read by researchers, and communities interested in how they communicate their past, present, and future." —Professor Emerita Gunilla Bradley Informatics School of ICT Royal Institute of Technology (KTH) Stockholm Sweden "Practitioners, researchers and theoreticians in Community Informatics will find a unique array of valuable perspectives in this book. It covers the interaction of communities, memories and technologies in a highly original way, with regard to its breadth and the number of case studies it presents. It incorporates contributions from 13 countries in all parts of our endangered planet, thus providing the international perspective that is critical to understanding how communities can use technology for societal good." —Professor Michel Menou.

Shared Memory Application Programming presents the key concepts and applications of parallel programming, in an accessible and engaging style applicable to developers across many domains. Multithreaded programming is today a core technology, at the basis of all software development projects in any branch of applied computer science. This book guides readers to develop insights about threaded programming and introduces two popular platforms for multicore development: OpenMP and Intel Threading Building Blocks (TBB). Author Victor Alessandrini leverages his rich experience to explain each platform's design strategies, analyzing the focus and strengths underlying their often complementary capabilities, as well as their interoperability. The book is divided into two parts: the first develops the essential concepts of thread management and synchronization, discussing the way they are implemented in native multithreading libraries (Windows threads, Pthreads) as well as in the modern C++11 threads standard. The second provides an in-depth discussion of TBB and OpenMP including the latest features in OpenMP 4.0 extensions to ensure readers' skills are fully up to date. Focus progressively shifts from traditional thread parallelism to modern task parallelism deployed by modern programming environments. Several chapter include examples drawn from a variety of disciplines, including molecular dynamics and image processing, with full source code and a software library incorporating a number of utilities that readers can adapt into their own projects. - Designed to introduce threading and multicore programming to teach modern coding strategies for developers in applied computing - Leverages author Victor Alessandrini's rich experience to explain each platform's design strategies, analyzing the focus and strengths underlying their often complementary capabilities, as well as their interoperability - Includes complete, up-to-date discussions of OpenMP 4.0 and TBB - Based on the author's training sessions, including information on source code and software libraries which can be repurposed

A comprehensive overview of OpenMP, the standard application programming interface for shared memory parallel computing—a reference for students and professionals. "I hope that readers will learn to use the full expressibility and power of OpenMP. This book should provide an excellent introduction to beginners, and the performance section should help those with some experience who want to push OpenMP to its limits." —from the foreword by David J. Kuck, Intel Fellow, Software and Solutions Group, and Director, Parallel and Distributed Solutions, Intel Corporation OpenMP, a portable programming interface for shared memory parallel computers, was adopted as an informal standard in 1997 by computer scientists who wanted a unified model on which to base programs for shared memory systems. OpenMP is now used by many software developers; it offers significant advantages over both hand-threading and MPI. Using OpenMP offers a comprehensive introduction to parallel programming concepts and a detailed overview of OpenMP. Using OpenMP discusses hardware developments, describes where OpenMP is applicable, and compares OpenMP to other programming interfaces for shared and distributed memory parallel architectures. It introduces the individual features of OpenMP, provides many source code examples that demonstrate the use and functionality of the language constructs, and offers tips on writing an efficient OpenMP program. It describes how to use OpenMP in full-scale applications to achieve high performance on large-scale architectures, discussing several case studies in detail, and offers in-depth troubleshooting advice. It explains how OpenMP is translated into explicitly multithreaded code, providing a valuable behind-the-scenes account of OpenMP program performance. Finally, Using OpenMP considers trends likely to influence OpenMP development, offering a glimpse of the possibilities of a future OpenMP 3.0 from the vantage point of the current OpenMP 2.5. With multicore computer use increasing, the need for a comprehensive introduction and overview of the standard interface is clear. Using OpenMP provides an essential reference not only for students at both undergraduate and graduate levels but also for professionals who intend to parallelize existing codes or develop new parallel programs for shared memory computer architectures.

This book examines the field of parallel database management systems and illustrates the great variety of solutions based on a shared-storage or a shared-nothing architecture. Constantly dropping memory prices and the desire to operate with low-latency responses on large sets of data paved the way for main memory-based parallel database management systems. However, this area is currently dominated by the shared-nothing approach in order to preserve the in-memory performance advantage by processing data locally on each server. The main argument this book makes is that such an unilateral development will cease due to the combination of the following three trends: a) Today’s network technology features remote direct memory access (RDMA) and narrows the performance gap between accessing main memory on a server and of a remote server to and even below a single order of magnitude. b) Modern storage systems scale gracefully, are elastic and provide high-availability. c) A modern storage system such as Stanford’s RAM Cloud even keeps all data resident in the main memory. Exploiting these characteristics in the context of a main memory-based parallel database management system is desirable. The book demonstrates that the advent of RDMA-enabled network technology makes the creation of a parallel main memory DBMS based on a shared-storage approach feasible.

Social theory needs to be completely rethought in a world of digital media and social media platforms driven by data processes. Fifty years after Berger and Luckmann published their classic text The Social Construction of Reality, two leading sociologists of media, Nick Couldry and Andreas Hepp, revisit the question of how social theory can understand the processes through which an everyday world is constructed in and through media. Drawing on Schütz, Elias and many other social and media theorists, they ask: what are the implications of digital medias profound involvement in those processes? Is the result a social world that is stable and liveable, or one that is increasingly unstable and unliveable?
