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 www.hp2c.ch. 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 requirements:

• 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: olaf.schenk@unibas.ch)
