The CoreGRID Network of Excellence (NoE) project began in September 2004. Two months later, in November 2004, the first CoreGRID Integra­ tion Workshop was held within the framework of the prestigious international Dagstuhl seminars. CoreGRID aims at strengthening and advancing long-term research, knowledge transfer and integration in the area of Grid and Peer-to- Peer technologies. CoreGRID is a Network of Excellence - a new type of project within the European 6th Framework Programme, to ensure progressive evolution and durable integration of the European Grid research community. To achieve this objective, CoreGRID brings together a critical mass of we- established researchers and doctoral students from forty-two institutions that have constructed an ambitious joint programme of activities. Although excellence is a goal to which CoreGRID is committed, durable integration is our main concern. It means that CoreGRID has to carry out activ­ ities to improve the effectiveness of European research in Grid by coordinating and adapting the participants' activities in Grid research, to share resources such as Grid testbeds, to encourage exchange of research staff and students, and to ensure close collaboration and wide dissemination of its results to the international community. Organising CoreGRID Integration Workshops is one of the activities that aims at identifying and promoting durable collaboration between partners involved in the network.

The Internet and the Web continue to have a major impact on society. By allowing us to discover and access information on a global scale, they have created entirely new businesses and brought new meaning to the term surf. In addition, however, we want processing, and increasingly, we want collaborative processing within distributed teams. This need has led to the creation of the Grid - an infrastructure that enables us to share capabilities, and integrate services and resources within and across enterprises. Future Generation Grids is the second in the CoreGRID series. This edited volume brings together contributed articles by scientists and researchers in the Grid community in an attempt to draw a clearer picture of the future generation Grids. This book also identifies some of the most challenging problems on the way to achieving the invisible Grid ideas.

Baum-Suchverfahren werden in der Informatik, insbesondere im Teilbereich der Künstlichen Intelligenz, zum Durchsuchen von Entscheidungsbäumen eingesetzt. Das vorliegende Buch befaßt sich mit Baum-Suchverfahren für eine spezielle Art von Entscheidungsbäumen, den Spielbäumen. Es werden zwei grundlegende Klassen von Spielbaum-Suchverfahren ausführlich behandelt: die Nullfenster-Suchverfahren, die den Baum in einer vorher festgelegten Reihenfolge durchsuchen, und die Zustandsraum-Suchverfahren, deren Suchabfolge dynamisch gesteuert ist. Der praktisch orientierte Spielprogrammierer findet in diesem Buch einen universell verwendbaren Grundstock von Baum-Suchalgorithmen für Zwei-Personen-Null-Summen-Spiele, wie z.B. Schach, Dame und Go. Neben den Algorithmen selbst werden ihm theoretische und empirische Bewertungskriterien an die Hand gegeben, mit denen er die zu erwartende Suchleistung eines Algorithmus abschätzen kann. Der an den theoretischen Grundlagen der Spielbaumsuche interessierte Leser findet in diesem Buch Ansätze zur Analyse der Suchabfolge und zur Berechnung der Sucheffizienz der Algorithmen. Den Ausgangspunkt bilden dabei die zu durchsuchenden Bäume, deren Knotenbeziehungen auf einfache Weise in mathematischen Gleichungssystemen beschrieben werden.

Scalable Coherent Interface (SCI) is an innovative interconnect standard (ANSI/IEEE Std 1596-1992) addressing the high-performance computing and networking domain. This book describes in depth one specific application of SCI: its use as a high-speed interconnection network (often called a system area network, SAN) for compute clusters built from commodity workstation nodes. The editors and authors, coming from both academia and industry, have been instrumental in the SCI standardization process, the development and deployment of SCI adapter cards, switches, fully integrated clusters, and software systems, and are closely involved in various research projects on this important interconnect. This thoroughly cross-reviewed state-of-the-art survey covers the complete hardware/software spectrum of SCI clusters, from the major concepts of SCI, through SCI hardware, networking, and low-level software issues, various programming models and environments, up to tools and application experiences.
