Subject: PhD course developed: Numerical Functional Analysis

As it might interest the readers of NA-digest I decided to post a note
on a course just developed and given to 14 NA graduate students in
Sweden. The course is a first introduction to Functional Analysis with
a particular emphasis on constructs and results that connect in
various ways to Numerical Analysis. For more information, including a
lecture schedule, assignments, and various in-class exercises, refer
to the course web- page,

In particular, a 'Student's book' includes the final essays by the
students. The format of the course was well appreciated and could
hopefully be of inspirational value.

Optimization: Algorithms and Applications
March 9-10, 2015
North-Pattaya, Chonburi, Thailand

Participants will obtain first-hand information about the latest
research in dynamic optimization and advanced control in Europe,
including industrial applications. The academic participants from
Europe and SEA will learn about current problems in industry in Europe
and SEA, and potential bottlenecks for the application of advanced
optimization-based methods.

Contribution to the reinforcement of EU-SEA ICT collaboration: The
workshop will create a basis for further collaborations in
cyber-physical systems, industrial automation and advanced computing
as participants from SEA countries and from Europe learn about the
current research and development work, get to know each other and
develop a joint understanding for the needs of industry, especially
under SEA's economical and structural conditions. It is expected to
stimulate research and development collaborations with industrial and
academic partners, including joint project proposals, and other follow
up activities.

Subject: Postdoc Position, Computational Scientist, RZG, Germany

In the framework of the DFG-funded SPPEXA program, the Computing
Center (RZG) of the Max-Planck Society is looking for a

Computational Scientist or Physicist (PostDoc)

for working on the highly scalable MPI code GENE. The GENE code is one
of the worldwide leading codes for numerical ab-initio simulation of
gyrokinetic plasma turbulence in fusion devices. Future exascale
supercomputer systems pose many challenges for parallel codes, among
them the effective usage of different parallelization levels
(vectorizing CPUs in many-core nodes in a multinode cluster) and the
problem of achieving resilience to hardware faults are considered most
important. The offered position will work on both problems by making
steps with GENE towards a MPI/OpenMP hybrid and fault-tolerant code.

The applicant should have a PhD in Physics, Mathematics, Computer
Science or a similar subject. A strong background in programming
(ideally with Fortran 90/2003), some experience with large code
projects (some 10000 lines of code) and high performance computing are
necessary. Knowledge of and experience with MPI and/or OpenMP are
highly appreciated.

The position will start as soon as possible and lasts until
31.12.2016. Given a positive evaluation of a successive funding
proposal an extension is possible. For further questions please
contact Dr. Tilman Dannert. Your application with a letter of
motivation and a CV should also be sent in German or English as one
PDF file to this address. You will find further information about the
