This two-volume set LNCS 9573 and LNCS 9574 constitutes the refereed proceedings of the 11th International Conference of Parallel Processing and Applied Mathematics, PPAM 2015, held in Krakow, Poland, in September 2015.The 111 revised full papers presented in both volumes were carefully reviewed and selected from 196 submissions. The focus of PPAM 2015 was on models, algorithms, and software tools which facilitate efficient and convenient utilization of modern parallel and distributed computing architectures, as well as on large-scale applications, including big data problems.

The most powerful computers work by harnessing the combined computational power of millions of processors, and exploiting the full potential of such large-scale systems is something which becomes more difficult with each succeeding generation of parallel computers. Alternative architectures and computer paradigms are increasingly being investigated in an attempt to address these difficulties. Added to this, the pervasive presence of heterogeneous and parallel devices in consumer products such as mobile phones, tablets, personal computers and servers also demands efficient programming environments and applications aimed at small-scale parallel systems as opposed to large-scale supercomputers. This book presents a selection of papers presented at the conference: Parallel Computing (ParCo2017), held in Bologna, Italy, on 12 to 15 September 2017. The conference included contributions about alternative approaches to achieving High Performance Computing (HPC) to potentially surpass exa- and zetascale performances, as well as papers on the application of quantum computers and FPGA processors. These developments are aimed at making available systems better capable of solving intensive computational scientific/engineering problems such as climate models, security applications and classic NP-problems, some of which cannot currently be managed by even the most powerful supercomputers available. New areas of application, such as robotics, AI and learning systems, data science, the Internet of Things (IoT), and in-car systems and autonomous vehicles were also covered. As always, ParCo2017 attracted a large number of notable contributions covering present and future developments in parallel computing, and the book will be of interest to all those working in the field.

Offshore drilling and constructions require exact knowledge of the geophysical properties of the seabed and sub-seabed, as unexpected objects can slow down or halt projects. This book presents the state-of-the-art in acoustic exploration of the seabed and sub-seabed, from initial designs in the 1980s to commercial contracting and operation of the Acoustic CorerTM in the last decade. The Acoustic CorerTM is a high-definition commercial acoustic sub-bottom imaging system, producing an “acoustic core” within which sub-seabed sedimentary characteristics and discrete buried objects larger than 0.5 m can be identified and mapped. It makes use of the innovative JYG-cross design, inspired by seismic reflection and uses Synthetic Aperture Sonar (SAS) multi-angle scattering in and within the seabed to deliver unprecedented imagery. This book was written by the inventor of these concepts, a known specialist in seabed acoustics, with help from an experienced academic and author. It is intended first and foremost as a “how-to” guide for offshore industries looking at techniques to make the installation of different types of structures safe and efficient.

This book constitutes the thoroughly refereed post-conference proceedings of the International Dagstuhl-Seminar on Efficient Algorithms for Global Optimization Methods in Computer Vision, held in Dagstuhl Castle, Germany, in November 2011. The 8 revised full papers presented were carefully reviewed and selected by 12 lectures given at the seminar. The seminar focused on the entire algorithmic development pipeline for global optimization problems in computer vision: modelling, mathematical analysis, numerical solvers and parallelization. In particular, the goal of the seminar was to bring together researchers from all four fields to analyze and discuss the connections between the different stages of the algorithmic design pipeline.

Studienarbeit aus dem Jahr 2017 im Fachbereich Informatik - Technische Informatik, Sprache: Deutsch, Abstract: Paralleles Rechnen ist die Zusammensetzung der Ergebnisse mehrerer Teilberechnungen zu einem Gesamtergebnis. Es existieren mehrere Gründe wie z.B. die Ausführungsdauer. Durch das Parallele Rechnen ist es bei Simulationen möglich viel Zeit zu sparen und die Ergebnisse schneller zu erhalten. Ein anderer Grund ist die Ressourcenbeschränktheit. Simulationen können die Kapazitäten (z.B. Speicherkapazität) eines einzigen Computers übertreffen. Um trotzdem die Simulation durchzuführen, könnte man mehrere Computer miteinander verbinden. Der letzte Grund den wir erwähnen ist die Komplexe Problemdarstellung. Es gibt Simulationen die so komplex sind, dass um ein Ergebnis zu erhalten, eine Parallele Bearbeitung die einzige Möglichkeit ist. Paralleles Rechnen wird in vielen verschiedenen Bereichen wie z.B. in der Wirtschaft (Big Data, Data Mining...) und in der Forschung (Physik, Mathematik...) verwendet.

Diese völlig überarbeitete Neuauflage bietet dem Leser eine gründliche Einführung in die Methode der Finiten Elemente, welche heute verstärkt zur numerischen Lösung von partiellen Differentialgleichungen eingesetzt werden. Die Theorie wird so weit entwickelt, daß der Leser mit Kenntnissen aus den Grundvorlesungen des Mathematikstudiums auskommt. Dem für die Praxis relevanten Mehrgitterverfahren und der Methode der konjugierten Gradienten wird ein breiter Platz eingeräumt. Ausführlich wird die Strukturmechanik als ein wichtiger und typischer Anwendungsbereich für Finite Elemente behandelt. Da dieser Aspekt in anderen Lehrbüchern kaum Berücksichtigung findet, wurde er in der Neuauflage stark überarbeitet und abgerundet. Als weitere Ergänzung ist vor allem die Diskussion von a posteriori Schätzern zu nennen.
