Optimizing HPC Applications with Intel (R) Cluster Tools takes the reader on a tour of the fast-growing area of high performance computing and the optimization of hybrid programs. These programs typically combine distributed memory and shared memory programming models and use the Message Passing Interface (MPI) and OpenMP for multi-threading to achieve the ultimate goal of high performance at low power consumption on enterprise-class workstations and compute clusters. The book focuses on optimization for clusters consisting of the Intel (R) Xeon processor, but the optimization methodologies also apply to the Intel (R) Xeon Phi (TM) coprocessor and heterogeneous clusters mixing both architectures. Besides the tutorial and reference content, the authors address and refute many myths and misconceptions surrounding the topic. The text is augmented and enriched by descriptions of real-life situations.

This book focuses on the theoretical and practical aspects of parallel programming systems for today's high performance multi-core processors and discusses the efficient implementation of key algorithms needed to implement parallel programming models. Such implementations need to take into account the specific architectural aspects of the underlying computer architecture and the features offered by the execution environment. This book briefly reviews key concepts of modern computer architecture, focusing particularly on the performance of parallel codes as well as the relevant concepts in parallel programming models. The book then turns towards the fundamental algorithms used to implement the parallel programming models and discusses how they interact with modern processors. While the book will focus on the general mechanisms, we will mostly use the Intel processor architecture to exemplify the implementation concepts discussed but will present other processor architectures where appropriate. All algorithms and concepts are discussed in an easy to understand way with many illustrative examples, figures, and source code fragments. The target audience of the book is students in Computer Science who are studying compiler construction, parallel programming, or programming systems. Software developers who have an interest in the core algorithms used to implement a parallel runtime system, or who need to educate themselves for projects that require the algorithms and concepts discussed in this book will also benefit from reading it.

Do popular forms of representing politics in the media endanger the quality of public communication? Or do they provide an appropriate modern entertaining way of putting politics across to wide sectors of the public? The present volume takes up this current discussion from a linguistic point of view. Anybody enquiring into changing political processes an a media society should look carefully at the evidence and beware of idealising myths, false comparisons and overhasty conclusions.

Das Schreckbild vom passiven Zuschauer, der hilflos am Tropf der Fernsehberieselung hängt und kommunikativ verkümmert, ist weit verbreitet. Was wirklich vor dem Fernseher geschieht, vor allem wie, worüber und wozu Zuschauer bei der gemeinsamen Rezeption sprechen, wurde jedoch bisher kaum erforscht. Dieses Buch gibt erstmals systematisch Einblick in die Vielfalt der Muster, Themen und Funktionen der spontanen Zuschauerkommunikation, durch die wir uns das Gesehene und Erlebte für unsere jeweilige Lebenswelt aneignen. Auf einer breiten Basis authentischer Daten und detaillierter Fallanalysen wird beschrieben, wie eigenständig, differenziert und produktiv wir mit den Inhalten des sogenannten Massenmediums Fernsehen umgehen (können). Jenseits aller Wirkungsannahmen zeigt sich somit: Was Fernsehen ist und macht, ist nicht zuletzt eine Frage seiner kommunikativen Aneignung.

Angesichts der Entwicklung der Textlinguistik und der Zunahme semiotischer, kulturwissenschaftlicher und medienbezogener Aspekte bei der Textbetrachtung wird der tradierte Textbegriff zunehmend in Frage gestellt. Der Band versammelt deshalb Antworten auf die von K. Adamzik und U. Fix gestellte und von der Gesellschaft fur Angewandte Linguistik mit einem Preisgeld ausgestattete Preisfrage "Brauchen wir einen neuen Textbegriff?". Es werden elf Beitrage veroeffentlicht, die die Auseinandersetzung mit dem Textbegriff unter verschiedenen Aspekten und in verschiedener Form fuhren und die zu durchaus kontroversen Antworten kommen. Drei Aufsatze von Herausgebern und Jurymitgliedern (Adamzik, Antos, Klemm), eine Sammlung von Textdefinitionen (Klemm) und eine Einfuhrung mit Laudatio (Fix) erganzen die Antworten.
