Die Datenmengen, die bei der Modellierung, der Simulation und der Überwachung von Umweltprozessen anfallen, sind heute schon so groß, daß sie nur noch mit Supercomputersystemen in verantwortbaren Zeiten sinnvoll bearbeitet werden können. Auch die Ergebnisdaten müssen weiter analysiert und interpretiert werden, sei es durch erfahrenes und DV-kundiges Fachpersonal, sei es durch weitergehende Transformationen und geeignete Formen der Darstellung. Die Visualisierung von Umweltdaten versucht, das umfangreiche und komplexe Datenmaterial mit Werkzeugen der Graphischen Datenverarbeitung in Form von Bildern darzustellen und dabei die Modellvorstellungen der Wissenschaftler und Ingenieure wiederzugeben, die in erster Linie Fachleute ihrer wissenschaftlichen und technischen Disziplinen sind und erst danach eventuell DV-Spezialisten. Dieser Band enthält die Beiträge einer Fachtagung, die der Fachbereich 4 "Informationstechnik und Technische Nutzung der Informatik" der Gesellschaft für Informatik veranstaltet hat. Schwerpunkte der Tagung waren die Visualisierung räumlicher Daten, die Anwendung von Hochleistungssystemen und die Visualisierung und Interaktion in Umweltinformationssystemen.

Parallel processing offers a solution to the problem ofproviding the processing power necessary to help understandand master the complexity of natural phenomena andengineering structures. By taking several basic processingdevices and connecting them together the potential exists ofachieving a performance many times that of an individualdevice. However, building parallel application programs istoday recognized as a highly complex activity requiringspecialist skills and in-depth knowledge. PARLE is aninternational, European based conference which focuses onthe parallel processing subdomain of informatics andinformation technology. It is intended to become THEEuropean forum for interchange between experts in theparallel processing domain and to attract both industrialand academic participants with a technical programmedesignedto provide a balance between theory and practice.This volume contains the proceedings of PARLE '93. The PARLEconference came into existence in 1987 as an initiative fromthe ESPRIT I programme and the format was revised in1991/92. PARLE '93 is the second conference with the newformat and was held in Munich.

For the fourth time, the Leibniz Supercomputing Centre (LRZ) and the Com- tence Network for Technical, Scienti c High Performance Computing in Bavaria (KONWIHR) publishes the results from scienti c projects conducted on the c- puter systems HLRB I and II (High Performance Computer in Bavaria). This book reports the research carried out on the HLRB systems within the last three years and compiles the proceedings of the Third Joint HLRB and KONWIHR Result and Reviewing Workshop (3rd and 4th December 2007) in Garching. In 2000, HLRB I was the rst system in Europe that was capable of performing more than one Tera op/s or one billion oating point operations per second. In 2006 it was replaced by HLRB II. After a substantial upgrade it now achieves a peak performance of more than 62 Tera op/s. To install and operate this powerful system, LRZ had to move to its new facilities in Garching. However, the situation regarding the need for more computation cycles has not changed much since 2000. The demand for higher performance is still present, a trend that is likely to continue for the foreseeable future. Other resources like memory and disk space are currently in suf cient abundance on this new system.

Informations- und Kommunikationstechnik erhalten als Hilfsmittel für Forschung und Lehre immer größere Bedeutung. Hochschulen verwenden daher einen erheblichen Anteil ihres Budgets darauf, IuK-Dienste hoher Zuverlässigkeit und Qualität bereitzustellen. Die technische Entwicklung macht es notwendig, dass Organisationsstruktur und Betriebskonzept in allen Bereichen so angepasst werden, dass sie einen effizienten Betrieb ermöglichen. Die Autoren erläutern am Beispiel der TU München die Realisierung einer effizienten, integrierten IT-Infrastruktur und deren Management. Beiträge der Universitäten Augsburg, Münster und Karlsruhe erlauben einen Vergleich mit ähnlichen Aktivitäten in Deutschland.

Welcome totheproceedings ofCloudComp 2009. A computing cloudis more thana collection of computer resources, because itpro- vides mechanisms to manage those resources. In a cloud computing platform, software is migrating from the desktop to the "clouds," promising users, at any time and anywhere, access totheirprograms anddata. Thisyear, 44 academic, industrial andstudent papers from all overthe world were submitted, of which 17were accepted as regular longpapers. Additionally, threewere included as shortpapers on hottopics. The Program Committee appreciates the time andeffortall of the researchers put into preparing theirpapers. Many thanks also to themembers oftheProgram Committee andtheexternal reviewers foralloftheirhard workin reading, evaluating, and providing detailed feedback. Without the contribu- tions of both of these groups, CloudComp would not have been such a lively symposium. The symposium featured keynote addresses by Jesus Villasante, Head of Unit, European Commission, Dane Walther, Director of Custom Engineering, Akamai Technologies Inc. Cambridge, MA, USA, Greg Malewicz, Google, Mountain View, CA,USA, andMauro Campanella, Consortium GARR, Italy.A scientific visitof the Leibniz Supercomputer Centre (LRZ), Bavarian Academy of Science, Garching (Munich), was organized during the conference. The visit was hosted byProf.A. Bode. We feel that the symposium willgrow and develop in its service to the research community within bothacademia andindustry.

The Leibniz Supercomputing Centre (LRZ) and the Bavarian Competence Network for Technical and Scienti?c High Performance Computing (KONWIHR) publish in the present book results of numerical simulations facilitated by the High P- formance Computer System in Bavaria (HLRB II) within the last two years. The papers were presented at the Fourth Joint HLRB and KONWIHR Review and - sult Workshop in Garching on 8th and 9th December 2009, and were selected from all progress reports of projects that use the HLRB II. Similar to the workshop two years ago, the majority of the contributed papers belong to the area of computational ?uid dynamics (CFD), condensed matter physics, astrophysics, chemistry, computer sciences and high-energy physics. We note a considerable increase of the user c- munity in some areas: Compared to 2007, the number of papers increased from 6 to 12 in condensed matter physics and from 2 to 5 in high-energy physics. Bio s- ences contributed only one paper in 2007, but four papers in 2009. This indicates that the area of application of supercomputers is continuously growing and entering new ?elds of research. The year 2007 saw two major events of particular importance for the LRZ. First, after a substantial upgrade with dual-core processors the SGI Altix 4700 superc- puter reached a peak performance of more than 62 Tera?op/s. And second, the n- pro?t organization Gauss Centre for Supercomputing e. V. (GCS) was founded on April 13th.

High-Performance Computers (HPC) have initiated a revolutionary develop ment in research and technology since many complex and challenging prob lems in this area can only be solved by HPC and a network in modeling, algo rithms and software. In 1998 the Deutsche Forschungsgemeinschaft (German Research Association) recommended to install an additional Federal High Performance Computer followed by the one in Stuttgart. In January 1999 the Wissenschaftsrat (German Science Council) decided that the Leibniz Rechenzentrum (Computing Center) of the Bavarian Academy of Sciences in Munich should run the second Federal High-Performance Computer in Ger many. The investment cost of this Hochstleistungsrechner in Bayern (HLRB) was borne by the Federal Government of Germany and the Free State of Bavaria whereas the operating cost was at the expense of the Bavarian Gov ernment only. The operation of the HLRB is organized in combination with the - Leibniz-Rechenzentrum (LRZ) of the Bavarian Academy of Sciences as the operating authority of the HLRB - Steering Committee of the HLRB - Competence Network for Technical/Scientific High-Performance Comp- ing in Bavaria (KONWIHR). In 2000 a Hitachi SR8000-Fl was installed. It was the first Teraflops Com puter in Germany and reached a peak performance of two Teraflops after an extension at the end of 2001. The goal of HLRB is to provide computer facil ities necessary to solve challenging scientific and technological problems that cannot be solved on big servers but require large (storage) high-performance (very fast) computers and efficient software.

Parallel computer architectures are now going to real applications! This fact is demonstrated by the large number of application areas covered in this book (see section on applications of parallel computer architectures). The applications range from image analysis to quantum mechanics and data bases. Still, the use of parallel architectures poses serious problems and requires the development of new techniques and tools. This book is a collection of best papers presented at the first workshop on two major research activities at the Universitiit Erlangen-Niirnberg and Technis che Universitiit Miinchen. At both universities, more than 100 researchers are working in the field of multiprocessor systems and network configurations and methods and tools for parallel systems. Indeed, the German Science Founda tion (Deutsche Forschungsgemeinschaft) has been sponsoring the projects under grant numbers SFB 182 and SFB 342. Research grants in the form of a Sonder forschungsbereich are given to selected German Universities in portions of three years following a thoroughful reviewing process. The overall duration of such a research grant is restricted to 12 years. The initiative at Erlangen-Niirnberg was started in 1987 and has been headed since this time by Prof. Dr. H. Wedekind. Work at TU-Miinchen began in 1990, head of this initiative is Prof. Dr. A. Bode. The authors of this book are grateful to the Deutsche Forschungsgemeinschaft for its continuing support in the field of research on parallel processing. The first section of the book is devoted to hardware aspects of parallel systems.
