Dieser Sammelband enthält die ausgearbeiteten Fassungen einiger Beiträge zu einem Workshop über "Numerische Algorithmen auf Transputer-Systemen", welcher im Rahmen der Aktivitäten zweier GAMM-Fachausschüsse am 31. 5. - 1. 6. 1991 in Heidelberg stattfand. Die etwa 120 Teilnehmer aus Mathematik, Physik, Informatik und den Ingenieurwissenschaften diskutierten theoretische und praktische Aspekte des Entwurfs und der Realisierung von numerischen Al gorithmen vornehmlich auf Transputer-basierten Parallelrechnern. Die starke Rolle der Transputer-Systeme spiegelte deren große Verbreitung an Hochschul instituten wieder. Seit Anfang 1990 wurden in der Bundesrepublik mehrere größere Parallelrechner dieser Art mit bis zu 320 Prozessoren installiert. Dazu kommen noch eine Vielzahl kleiner Entwicklungssysteme bis hinunter zu ein zelnen Transputer-Boards in Tischrechnern. Dies hat zu einem weitverbreite ten Interesse an den mit der Transputer-Technologie verbundenen Hard- und Software-Fragen geführt. Die Präsenz der anderen Parallelrechnertypen vor nehmlich US-amerikanischer Herkunft blieb dagegen auf relativ wenige Instal lationen in größeren Instituten und Rechenzentren beschränkt. Im Zuge der breiteren Verfügbarkeit von Parallelrechnern aller Größenordnun gen befaßt sich eine zunehmende Zahl von Arbeitsgruppen an Universitäten und in außeruniversitären Forschungseinrichtungen mit der Entwicklung von parallelen Algorithmen und deren Anwendung für wissenschaftliche und tech nische Problemstellungen. Diese Entwicklung folgt dem internationalen Trend im wissenschaftlichen Rechnen hin zur Nutzung von Mehrprozessorsystemen zur Steigerung der numerischen Rechenleistung. Da abzusehen ist, daß die kommenden Hochleistungsrechner wohl durchgehend parallele Architekturen haben werden, ist es wichtig, bereits frühzeitig möglichst viele Erfahrungen mit der Parallelisierung von Algorithmen und ihrer Implementierung zu sammeln.

The so-called boundary element methods BEM, i.e. finite element approxima tions of boundary integral equations have been improved recently even more vividly then ever before and found some remarkable support by the German Research Foundation DFG in the just finished Priority Research Program "boundary element methods" . When this program began, we could start from several already existing particular activities which then during the six years initiated many new re sults and decisive new developments in theory and algorithms. The program was started due to encouragement by E. Stein, when most of the later par ticipants met in Stuttgart at a Boundary Element Conference 1987. Then W. Hackbusch, G. Kuhn, S. Wagner and W. Wendland were entrusted with writing the proposal which was 1988 presented at the German Research Foun dation and started in 1989 with 14 projects at 11 different universities. After German unification, the program was heavily extended by six more projects, four of which located in Eastern Germany. When we started, we were longing for the following goals: 1. Mathematicians and engineers should do joint research. 2. Methods and computational algorithms should be streamlined with re spect to the new computer architectures of vector and parallel computers. 3. The asymptotic error analysis of boundary element methods should be further developed. 4. Non-linear material laws should be taken care of by boundary element methods for crack-mechanics. 5. The coupling of finite boundary elements should be improved.

Main aspects of the efficient treatment of partial differential equations are discretisation, multilevel/multigrid solution and parallelisation. These distinct topics are covered from the historical background to modern developments. It is demonstrated how the ingredients can be put together to give an adaptive and parallel multilevel approach for the solution of elliptic boundary value problems. Error estimators and adaptive grid refinement techniques for ordinary and for sparse grid discretisations are presented. Different types of additive and multiplicative multilevel solvers are discussed with respect to parallel implementation and application to adaptive refined grids. Efficiency issues are treated both for the sequential multilevel methods and for the parallel version by hash table storage techniques. Finally, space-filling curve enumeration for parallel load balancing and processor cache efficiency are discussed.

Mathematical Visualization is a young new discipline. It offers efficient visualization tools to the classical subjects of mathematics, and applies mathematical techniques to problems in computer graphics and scientific visualization. Originally, it started in the interdisciplinary area of differential geometry, numerical mathematics, and computer graphics. In recent years, the methods developed have found important applications. The current volume is the quintessence of an international workshop in September 1997 in Berlin, focusing on recent developments in this emerging area. Experts present selected research work on new algorithms for visualization problems, describe the application and experiments in geometry, and develop new numerical or computer graphical techniques.

The combination of fast, low-latency networks and high-performance, distributed tools for mathematical software has resulted in widespread, affordable scientific computing facilities. Practitioners working in the fields of computer communication networks, distributed computing, computational algebra and numerical analysis have been brought together to contribute to this volume and explore the emerging distributed and parallel technology in a scientific environment. This collection includes surveys and original research on both software infrastructure for parallel applications and hardware and architecture infrastructure. Among the topics covered are switch-based high-speed networks, ATM over local and wide area networks, network performance, application support, finite element methods, eigenvalue problems, invariant subspace decomposition, QR factorization and Todd-Coxseter coset enumeration.

Dieser Band ist der vierte einer Reihe, der die interessantesten Anwendungen rund um den Transputer beschreibt. Anhand von Projekten, die Anwender aus Industrie, Forschung, Lehre und Entwicklung durchgeführt haben, wird dem Leser sowohl eine Übersicht über das zur Zeit Machbare vermittelt, als auch ein Werkzeug an Hand gegeben, das ihm bei der Eingrenzung und Lösung der eigenen Probleme helfen kann. Die in dem Band behandelten Schwerpunkte haben sich im Vergleich zu den Vorjahren erwartungsgemäß leicht verschoben; waren es in der Anfangszeit noch überwiegend Innovationsprobleme, so treten nun die Transputer-Anwendungen eindeutig in den Vordergrund. Dementsprechend ergab sich in diesem Jahr die folgende Einteilung: Transputer-Systeme:Systemprogrammierung und Evaluation Benutzeroberflächen und Hard-/Softwareumgebung Sprachen und Algorithmenentwicklung, Numerik Transputer-Anwendungen:Bildverarbeitung und Grafik Modellbildung und Simulation Meßtechnik und Signalverarbeitung Dieser Band verschafft durch sein breites Spektrum der beschriebenen Anwendungen und die Vielfalt der vertretenen Disziplinen sowohl erfahrenen Anwendern, als auch solchen, die es erst werden wollen, einen geeigneten Überblick. Er kann dadurch als Quelle und Kontaktpool für bereits gemachte Erfahrungen oder auch als Nachschlagewerk dienen.
