Subject: Multiple Research Positions: HPC at the University of Basel

The Math&CS Departments at the University of Basel are seeking applications
for one Ph.D. (3 years) and two postdoctoral positions (3 years) to conduct
research within the Swiss HP2C Petascale Computing Initiative.

These positions are part of an ongoing effort at U Basel to develop scalable
parallel inversion methods with application in computational wave propagation
for 3D inhomogeneous media.

Research issues include scalable parallel methods for large-scale nonlinear
optimization, discontinuous Galerkin finite element methods, algorithmic
re-engineering of large-scale Earth Science models involving solving partial
differential equations, and emerging multi-core/multi-threaded HPC
technologies especially GPU devices.

For all positions we expect experience and strong interest in programming and
high-performance computing. We are particularly interested in researchers from
the area of computational science with interests in optimizing computational
algorithms and their implementation (scaling, load balancing, etc.) on
petascale architectures including programming paradigms and languages (e.g.
PGAS, CUDA, OpenCL language directives and extensions, etc.)

The projects are funded by the highly collaborative High Productivity High
Performance Computing (HP2C) initiative and the positions will be open
starting March 1, 2010, or later. Details about HP2C are available at

Successful candidates will also have opportunities to work on leading edge
software and hardware technologies and to collaborate with internationally
renowned scientific research groups and supercomputing centers as well as with
HPC vendors.

The research positions have the following requirements:
- Demonstrated experience and expertise in the areas of focus.
- Substantial code development experience in C/C++. Experience with
GPU programming using CUDA is highly desirable.
- Demonstrated experience with numerical methods, e.g., finite elements,
inverse problems, scalable solvers, or nonlinear optimization.
- Working knowledge of parallel programming languages and systems.
- Knowledge of German is not a pre-requisite.

The postdoctoral research positions have additionally the following
- At least two years of experience in HPC.
- A doctoral degree in Applied Mathematics, or Computer Science with a
background in scientific computing and parallel computation.

Applications are accepted until positions are filled. Please send a complete
application with CV, a statement of research interests (one page), names of
two references with e-mail addresses in PDF format to: Olaf Schenk (e-mail:

Subject: PostDoc and PhD positions in Scientific GPU Computing

One Post Doc position (2 years) and two PhD positions (3 years) are
available in the area of Scientific GPU Computing, starting April 1,
2010. All three positions are with DTU Informatics ( at the
Technical University of Denmark, and they are financed by a grant from
the Danish Council for Independent Research.

The positions are part of the research project "Desktop Scientific
Computing on Consumer Graphics Cards." The aim of this project is to
develop a framework for using GPUs and similar many-core hardware
accelerators for desktop scientific computing, in collaboration with
several international contacts and in such a way that the technology
from an early stage of the project is useful in science and industry.
The core activity of the project is the development, implementation,
and testing of computational algorithms suited for GPU computing.

The Post Doc project involves the development of performance prediction
models and a profiler environment, as well as computational modules
for selected core computational tasks in scientific computing (in
collaboration with the PhD projects). The Post Doc will also be
responsible for collaboration and interaction with international
research contacts, and for establishing and maintaining a national
network between academia and industry.

The two PhD projects focus on computational methods for dynamical
optimization and PDE solvers, respectively. The computational
bottlenecks in these computations are the dense and sparse matrix
computations, and we aim to develop high-performance algorithms that
overcome these bottlenecks using GPU-based computing. The algorithms
have applications to other areas such as constrained optimization
and computational tomography.

Candidates should have a background in CSE, applied mathematics, or
scientific computing and, for the Post Doc position, a PhD degree
(or equivalent). Preference will be given to candidates who can
document programming skills in high-performance and/or multi-core
scientific computing, and in addition have a background in numerical
methods for large-scale problems.

For more information about the positions and how to apply, follow the
links on the university’s vacancy home page:

The Scientific Computing section is responsible for teaching in
high-performance/scientific computing, and the research includes
inverse problems, model-predictive control, high-order methods,
appearance modelling, and HPC. We offer a cross-disciplinary
research environment with activities in applied mathematics and
scientific computing, with contacts to academia and industry.
