info  Multiple Shooting and Time Domain Decomposition Methods (MuS-TDD) Thomas Carraro, Michael Geiger, Stefan Körkel, Rolf Rannacher May 6-8, 2013 ECTS-Points: 1
Abstract, registration & information:
The workshop treats recent trends in multiple shooting for the solution of boundary value and optimization problems for differential equations, in particular optimal control. Especially for PDE, multiple shooting is discussed in the wider framework of various time domain decomposition methods. Altogether, the range from numerical analysis and algorith- mic aspects to challenging applications is covered.

The Fundamental Need for Interactions Between Mathematical Theory, Computer Simulations, and Experiments ? A Case Study from Iterative Learning Control

Viewing the relatively new field of Iterative Learning Control (ILC) from a mathematical perspective can easily guide one to work on what appear to be the most relevant research problems, but they are in fact
useless. One expects simulations to assist in focusing the research directions, but cases are shown where they easily lead one to wrong
conclusions. Then the experimentalist might take over to make things work in hardware, but again he can be guided to wrong conclusions.

This case study shows that the interplay between theory, simulations, and experiments has been fundamental to the development of the ILC
field, each approach helping the others to focus on the real issues and not make wrong conclusions. We note that one of the strengths of IWR is its ability to approach problems from all three directions.

DOpElib: The di erential equations and optimization environment

C. Goll, Heidelberg University
T. Wick, UT Austin
W. Wollner, University of Hamburg

We present our software library DOpElib based on deal.ii. In our talk we introduce the
aims of the project, numerical examples, and future directions.
The goal of DOpElib is to combine the advantages of deal.ii, like, for example, various
nite elements, algorithms for local mesh re nement, and iterative linear solvers, with
modular software techniques for highlevel algorithms such as time-stepping schemes, non-
linear solvers, and optimization algorithms.
We will discuss the requirements on the implementation of the di erent parts for this mod-
ularity to work. This will be demonstrated along the lines of stationary and nonstationary
for linear and nonlinear PDEs and optimization problems.

Abstract, registration & information:
The German Climate Computing Center (DKRZ) is a national service center for climate and Earth system research in Germany. DKRZ provides high performance computing platforms, sophisticated and high capacity data management and superior services for premium climate science.

With the concept of remote 3D visualization in a high performance computing environment and appropriate visualization software solutions,
many of the challenges posed today by typical climate simulation data can potentially be faced.

By using examples from the practical work with results from climate models, the talk will give an overview on climate, climate models and the data
which has to be analyzed, followed by an brief overview some solutions interactive data visualization in this domain. At DKRZ, "Avizo Green"
(by VSG) is used for the interactive 3D-visualization of time dependent and multivariate climate simulation data.

Das Deutsche Klimarechenzentrum (DKRZ) betreibt als nationales Servivcezentrum für die Klima- und Erdsystemforschung in Deutschland
Hochleistungsrechner und Datenspeicher, ergänzt durch eine umfassende Unterstützung zur effektiven Nutzung der Systeme und weitere Dienste rund um den Arbeitsprozess der Wissenschaftler.

Mit dem Konzept des netzwerkbasierten 3D-Renderings im Kontext eines Hochleistungsrechenzentrums können Anwender an ihrem Arbeitsplatz die umfangreichen Modellergebnisse visualisieren und analysieren. Dabei ist eine domänenspezifische Anwendungssoftware, die auf die besonderen
Anforderungen dieses Wissenschaftszweiges eingeht, von großem Vorteil.

Anhand vieler Beispiele aus der praktischen Arbeit mit Simulationsergebnissen wird in dem Vortrag ein kurzer Überblick über Klima, Klimamodellierung
und ihrer Ergebnisse gegeben. Am DKRZ wird Avizo Green, ein kommerzielles
Visualisierungssystem mit einigen domänensprezifischen Anpassungen, für die
interaktive 3D-Visualisierung der Simulationsdaten eingesetzt.
