Wilhelm Niethammer (1933-2023)
Wilhelm Niethammer, professor emeritus at the University of Karlsruhe,
assed away at his home in Karlsruhe on March 17, 2023. Born in
Unterjettingen, a small village close to Stuttgart, he studied
mathematics with minor in physics at the universities of Stuttgart and
Tuebingen, where his mathematical interests were strongly influenced
by the "three K's" (E. Kamke, H. Kneser, K. Knopp). Originally, he
wanted to become a teacher but then changed to academia. He completed
his doctoral thesis under the supervision of Karl Zeller in 1964. In
this dissertation, he applied algorithms and ideas from complex
analysis to the iterative solution of linear systems of algebraic
equations, a topic which he was concerned with throughout his
scientific life.

Wilhelm Niethammer continued this academic career at the University of
Bochum. In 1970, he was appointed professor at the University of of
Mannheim. In 1978, he accepted the call to the professorship
"Numerische Mathematik und Grossrechenanlagen" at the University of
Karlsruhe, where he headed the "Institut fuer Praktische Mathematik"
until his retirement in 2002.

Wilhelm Niethammer was well known for his work in constructive complex
analysis and numerical linear algebra. He supervised 17 PhD
dissertations and several of his students went on to academic
positions. His students and colleagues remember him as a competent,
generous, helpful and always kind person. He served the mathematical
community in many other ways, e.g., he was chair of the Department of
Mathematics in Karlsruhe, he served as "Fachgutachter" for applied
mathematics on behalf of the Deutsche Forschungsgemeinschaft (DFG) and
led the DFG advisory board responsible for mathematics in the
1990's. In addition he was on the editorial board of various
mathematical journals and, together with Richard S. Varga, organised
several conferences at the Oberwolfach Research Institute for
Mathematics. Having been an enthusiastic mountain hiker (he mastered
the Kilimanjaro in his late 50's), these conferences were famous for
their hikes, starting with a steepest ascent right from the conference
center.

Wilhelm Niethammer is survived by this wife and his two children, his
daughter Barbara Niethammer being herself a well-known professor for
Applied Analysis at the Hausdorff Center for Mathematics in Bonn.

Subject: Enhancing reproducibility of research papers in SISC, JSC and JCP


The following will be published as a joint editorial in SISC, JSC and
JCP:

Reproducibility, that is, the ability to reproduce results obtained by
others, is a core principle of the scientific method. In a concerted
effort to enhance reproducibility in the area of scientific computing
research, three of the leading journals in the scientific computing
field will now invite authors, as part of the article submission
process, to make the code and data publicly available that allow the
results of their paper to be reproduced.

At article submission, the SIAM Journal on Scientific Computing
(SISC), the Journal of Scientific Computing (JSC), and the Journal of
Computational Physics (JCP) encourage authors to provide a link to
their code and data files hosted in either a public git repository
(e.g., on GitHub or Bitbucket), an open repository with DOI
identification such as Zenodo or Mendeley Data, or journal
supplementary materials.

At JCP and JSC, the link pointing to the code and data will be
published prominently together with the paper. At SISC, authors may
request a "SISC Reproducibility Badge: code and data available" which
will be published with the paper as a recognition that the paper
follows reproducibility principles.

While we acknowledge that it is not always possible for authors to
make their code and data available, there are many good reasons to
encourage authors to do so, including enhanced visibility and adoption
of their work by the research community. We hope sincerely that many
authors will take advantage of these new options to enhance and
highlight the reproducibility of their scientific computing
publications.

Subject: Postdoc Position, Computational Design Optimization, Sweden


The Department of Computing Science at Umea University, Sweden invites
applications for a postdoctoral fellow in the field of Computational
Design Optimization for Wave Propagation Problems. The employment is
full-time for two years starting 2023-06-01 or by agreement.

The project centers around the development of optimization methods for
the design of devices where wave propagation effects are crucial for
performance. Based on the applicant's background, interest, and
skills, the research can be directed in various ways, involving
acoustic as well as electromagnetic wave propagation. Of current
interest for acoustics is the design of devices in the context of
significant loss effects, for instance so- called acoustic black holes
or small-size acoustic devices such as MEMS microphones and micro
loudspeakers. Of interest for electromagnetics is components to enable
efficient radar technologies for monitoring or imaging targets
embedded in lossy media. Ground penetrating radars (GPRs) and radars
for vital signs monitoring of humans are examples of how such
technologies can be applied.

A major part of the research will involve fundamental methods
development. Thus, considerable focus will be given to the development
of accurate and efficient mathematical models and optimization schemes
as well as to efficient implementation of the methods in appropriate
software.

Subject: Postdoc Position, Grammar-guided Multigrid, France


A two-year Postdoc position is available at Cerfacs, Toulouse. The
project aims to develop concepts and a toolchain based on artificial
intelligence to automatically generate a performant preconditioner for
a Krylov subspace iterative solver for the solution of linear systems
arising from a discretized Stokes problem. We will focus in particular
on a geometric multigrid preconditioner for the (1,1)-block, here, the
Laplace operator, to ensure the scalability of the solver when passing
to large-scale problems. The solver will be broken down into
components, which are then recombined in an optimal manner for
predefined criteria, using evolutionary algorithm design
techniques. The particular difficulty to develop such a toolchain for
saddle point systems is the large number of possible combinations of
solution techniques, e.g., preconditioned Krylov subspace solvers,
Schur complement approaches, deflation and augmentation techniques, or
also monolithic multigrid solvers on the whole block system. As final
step, we envisage to obtain executable code applying the best guess
solver through automatic code generation.

Required profile: PhD with experience in one or several of the
following domains: applied mathematics, computer science, iterative
solvers, numerical linear algebra, artificial intelligence, high
performance computing.
