Subject: ViennaCL - A library for linear algebra on GPUs

We are proud to announce the Vienna Computing Library (ViennaCL), an
open source scientific computing library based on OpenCL and written in
C++ (a MATLAB interface is also available). It allows simple, high-level
access to the vast computing resources available on parallel
architectures such as GPUs and is primarily focused on common linear
algebra operations (BLAS level 1 and 2) and the solution of large
systems of equations by means of iterative methods (CG, BiCGStab and
GMRES) with an optional ILUT preconditioner.

For those using ublas (part of the Boost library) already, the iterative
solvers implemented in ViennaCL can directly be used, even if no
suitable GPU is available on the target machine.

More information can be found on the project homepage located at

The department of Computer Science of the K.U.Leuven and the
department of Mathematics and Computer Science of the Universiteit
Antwerpen are partners in the ExaScience Lab. They are responsible
for the research and development of numerical algorithms for the
future exascale hardware. New algorithms will have to take into
account the volatile nature of hardware components, energy
consumption (in addition to flop count), and a new programming model
based on PGAS languages. Specific aims are load balancing, iterative
linear system solvers, time integration for mesh-based and particle
based models for millions of parallel threads.

There are several openings for PostDoctoral researchers.
Candidates should have expertise in at least some of the following areas:
- Parallel scientific computing,
- Computer programming in C, C++ with MPI or PGAS languages,
- Iterative solvers based on Krylov subspace methods,
- Numerical methods for fluid dynamics or MHD, preferentially based
on the AMR method,
- Development of high-performance particle in cell (PIC) methods,
- Optimization of numerical kernels with respect to the underlying hardware.

The researchers will have access to large parallel computer
facilities and to a stimulating research environment within the
ExaScience Lab. They will work in close collaboration with experts in
computer science, scientific computing, computer hardware and
visualization and application domains such as space weather. There

Subject: Postdoc in Particle Methods at Mid Sweden University

Particle methods is a very promising and successfull class of techniques to
solve difficult problems in science. They have been used in physics for
e.g., in celestial simulations, mechanics, molecular dynamics etc.

It is evident that a given particle method solves some type of
differential equation. The question announced in this project is from the
opposite point of view: given a differential equation (possibly
non-linear) how
can we construct a particle method in order to solve it efficiently?

An important example is the Schrodinger type of equation, but the
approach will
be more general to cover a large class of differential equations.

The interested candidate should have a solid background in computational
or scientific computing and an interest in applied mathematics.

The salary will be between 3-4000 Euro/month depending on
qualifications. The
position will run from September 2010 to December 2010 with the
possibility of
extension in 2011.

Subject: PhD/Postdoc on Reduction of Chemical Reaction Mechanisms

The recently established Virtuhcon Research Center at the TU
Bergakademie Freiberg, Germany ( invites applications
for the position of a doctoral or postdoctoral research associate. The
research group “Reacting Flow Systems”, to which this position is
attached, investigates high temperature conversion processes occurring
during gasification of coal/oil/natural gas by direct reduction. Its
focus is the modeling and simulation of single and multi-phase
turbulent flows and their interaction with homogeneous and
heterogeneous chemical reactions on high performance computers.

Detailed chemical reaction mechanisms must be used to describe the
complex gas phase chemistry. The candidate will focus on the
reduction of these mechanisms, such that they can be employed for
three-dimensional CFD simulations. The reduction procedure is based on
analysis and characterization of large systems of ordinary and partial
differential equations. The significant reactions and chemical species
are identified such that global quantities such as ignition delay
laminar flame speed and flammability limits can be reproduced with the
smaller mechanism according to the temperature, pressure and chemical
composition of the mixture. The development of new methods for
reduction procedures will be conducted in close collaboration with the
Institute of Numerical Analysis and Optimization at the TU
Bergakademie Freiberg.

Salary: TV-L 13

Candidates should have a PhD or Diploma/MSc degree (willing to pursue
a PhD degree) in natural or engineering sciences (mathematics, physics
or mechanical engineering with specialization in numerical
methods). Experience in numerical solu- tion methods for differential
equations, basic knowledge of Unix/Linux and at least one of the
programming languages FOR- TRAN, C or C++ is preferred. The position
is funded by the Federal Ministry of Education and Research and
appointments will therefore be made on a fixed term basis for up to
five years.

Enquiries about the position can be addressed to
