This book treats the computational use of social concepts as the focal point for the realisation of a novel class of socio-technical systems, comprising smart grids, public display environments, and grid computing. These systems are composed of technical and human constituents that interact with each other in an open environment. Heterogeneity, large scale, and uncertainty in the behaviour of the constituents and the environment are the rule rather than the exception. Ensuring the trustworthiness of such systems allows their technical constituents to interact with each other in a reliable, secure, and predictable way while their human users are able to understand and control them. "Trustworthy Open Self-Organising Systems" contains a wealth of knowledge, from trustworthy self-organisation mechanisms, to trust models, methods to measure a user's trust in a system, a discussion of social concepts beyond trust, and insights into the impact open self-organising systems will have on society.

Organic Computing has emerged as a challenging vision for future information processing systems. Its basis is the insight that we will increasingly be surrounded by and depend on large collections of autonomous systems, which are equipped with sensors and actuators, aware of their environment, communicating freely, and organising themselves in order to perform actions and services required by the users.

These networks of intelligent systems surrounding us open fascinating ap-plication areas and at the same time bear the problem of their controllability. Hence, we have to construct such systems as robust, safe, flexible, and trustworthy as possible. In particular, a strong orientation towards human needs as opposed to a pure implementation of the tech-nologically possible seems absolutely central. The technical systems, which can achieve these goals will have to exhibit life-like or "organic" properties. "Organic Computing Systems" adapt dynamically to their current environmental conditions. In order to cope with unexpected or undesired events they are self-organising, self-configuring, self-optimising, self-healing, self-protecting, self-explaining, and context-aware, while offering complementary interfaces for higher-level directives with respect to the desired behaviour. First steps towards adaptive and self-organising computer systems are being undertaken. Adaptivity, reconfigurability, emergence of new properties, and self-organisation are hot top-ics in a variety of research groups worldwide.

This book summarises the results of a 6-year priority research program (SPP) of the German Research Foundation (DFG) addressing these fundamental challenges in the design of Organic Computing systems. It presents and discusses the theoretical foundations of Organic Computing, basic methods and tools, learning techniques used in this context, architectural patterns and many applications. The final outlook shows that in the mean-time Organic Computing ideas have spawned a variety of promising new projects.

HiPEAC2009wasthe fourthedition ofthe HiPEACconferenceseries.This c- ferenceseriesislargelyassociatedwiththeFP7NetworkofExcellenceHiPEAC2. The ?rst three editions of the conference in Barcelona (2005), Ghent (2007) and G] oteborg (2008) attracted a lot of interest with more than 200 attendees at the last two editions and satellite events. It is a great privilege for us to welcome you to the fourth HiPEAC conference in the beautiful, touristic city of Paphos, Cyprus. The o?erings of this conference are rich and diverse. We o?er attendees a set of seven workshopson topics that are central to the HiPEAC network roadmap: multi-cores, simulation and performance evaluation, compiler optimizations, - sign reliability, recon?gurable computing, and interconnection networks. Ad- tionally, a tutorial on design reliability is o?ered. Theconferenceprogramwasasrichaslastyear's.Itfeaturedmanyimportant andtimelytopicssuchasmulti-coreprocessors, recon?gurablesystems, compiler optimization, power-awaretechniquesand more.The conferencealso o?ered two keynote speeches: Tilak Agerwala from IBM Research presenting the view from a major industry player, and Fran, cois Bodin from CAPS-Entreprise presenting the view of a start-up. There were several social activities during the conference o?ering ample - portunity for informal interaction. These included a reception, an excursion to various archeological sites and a banquet at a traditional tavern. Thisyearwereceived97papersubmissions, ofwhich14wereco-authoredbya Program Committee member. Papers were submitted from 20 di?erent nations (approximately 46% from Europe, 15% from Asia, 32% from North America, 4% from Africa and the Middle East, and 3% from South America), which is an indicator of the global visibility of the conference."

Where is system architecture heading? The special interest group on Computer and Systems Architecture (Fachausschuss Rechner- und Systemarchitektur) of the German computer and information technology associations GI and ITG a- ed this question and discussed it during two Future Workshops in 2002. The result in a nutshell: Everything will change but everything else will remain. Future systems technologies will build on a mature basis of silicon and IC technology, onwell-understoodprogramminglanguagesandsoftwareengineering techniques, and on well-established operating systems and middleware concepts. Newer and still exotic but exciting technologies like quantum computing and DNA processing are to be watched closely but they will not be mainstream in the next decade. Although there will be considerable progress in these basic technologies, is there any major trend which uni?es these diverse developments? There is a common denominator - according to the result of the two - ture Workshops - which marks a new quality. The challenge for future systems technologies lies in the mastering of complexity. Rigid and in?exible systems, built under a strict top-down regime, have reached the limits of manageable complexity, as has become obvious by the recent failure of several large-scale projects. Nature is the most complex system we know, and she has solved the problem somehow. We just haven't understood exactly how nature does it. But it is clear that systems designed by nature, like an anthill or a beehive or a swarm of birds or a city, are di?erent from today's technical systems that have beendesignedbyengineersandcomputerscientists.

This monograph surveys architectural mechanisms and implementation techniques for exploiting fine-grained and coarse-grained parallelism within microprocessors. It starts with a review of past techniques, continues with a comprehensive account of state-of-the-art techniques used in microprocessors that covers both the concepts involved and implementations in sample processors, and ends with a thorough review of the research techniques that will lead to future microprocessors.

Die grundlegenden Prinzipien von Mikrocontrollern und Mikroprozessoren: Detailliert erlautern die Autoren den neuesten Stand der Technik, alle wichtigen Entwicklungstendenzen und den aktuellen Forschungsstand. Ferner analysieren sie in der Praxis haufig verwendete Mikrocontroller und Mikroprozessoren in ihrer Funktionsweise und schildern zukunftsweisende Technologien. Dieses Buch eignet sich besonders fur Studierende der Informatik oder Elektrotechnik im fortgeschrittenen Grundstudium oder zu Beginn des Hauptstudiums. Es ist ebenso empfehlenswert fur Fachleute, die sich mit Planung, Entwicklung und Einsatz dieser Hardware-Bausteine befassen."

Multiprozessorsysteme, die aus vielen "billigen" Mikroprozessoren aufgebaut sind, erschlieBen aufgrund ihrer hohen Leistungsfahigkeit immer neue Anwendungsberei che. Eine Voraussetzung fiir den Einsatz von Multiprozessorsystemen ist jedoch die Parallelisierbarkeit eines Problems, d. h. die Aufteilung in Teilprobleme, die ver schiedene Prozessoren gleichzeitig bearbeiten konnen. Da ein ProzeBwechsel, also ein Wechsel von einem Teilproblem zu einem anderen, einen hohen Verwaltungsauf wand bedeutet, lassen sich heutige Multiprozessorsysteme nur dann effizient einset zen, wenn jedes dieser Teilprobleme so urnfangreich ist, daB es eine relativ lange Ausfiihrungszeit benotigt. Urn statt dieser grobkornigen zusatzlich auch feinkornige Parallelitat nutzen zu konnen, werden neuartige Prozessorarchitekturen entwickelt, die einen schnellen ProzeBwechsel ennoglichen. Ais besonders geeignet erscheinen Datenf/ufJrechner, die jedoch nach einem vollig anderen Architekturprinzip als heutige Mikroprozessoren arbeiten. Beim DatenfluB prinzip wird die Befehlsausfiihrung allein durch die Verftigbarkeit der Operanden des Maschinenbefehls ausgelost, so daB ein ProzeBwechsel nach jeder Befehlsausfiih rung eintreten kann. Weiterhin geeignet sind Multithreaded-von-Neumann-Architek turen, die das Architekturprinzip modernster Mikroprozessoren urn die Hihigkeit zu schnellen ProzeBwechseln erweitern, sowie Hybridarchitekturen, die in dem Spek trum zwischen DatenfluB- und von-Neumann-Prinzip einzuordnen sind. Nach einer Einfiihrung in die Prinzipien von DatenfluBrechnern und DatenfluBspra chen werden im vorliegenden Buch Parallelarbeitstechniken in "konventionellen" Prozessorarchitekturen vorgestellt. Die friihen, statischen DatenfluBrechner, die groBen, dynamischen DatenfluBrechnerprojekte, die neuesten Entwicklungen von Multithreaded-DatenfluBarchitekturen, die Large-Grain-DatenfluBarchitekturen und weitere DatenfluB-/von-Neumann-Hybridarchitekturen bilden den Kern des Buches. Ein letztes Kapitel behandelt die Multithreaded-von-Neumann-Architekturen und schlieBt damit die letzte Lticke im Architekturspektrum yom DatenfluB- bis zum von Neumann-Prinzip."
