Postdoctoral Position: Multiphysics simulations for geodynamics on heterogeneous exascale systems (m/w/d)
The BMBF-funded position is part of the CoMPS project, which is a multidisciplinary project combining the fields of mathematics, computer science, geophysics, and high-performance computing. It aims to improve the performance of the matrix-free finite-element-based framework HyTeG, in particular by techniques for data reduction through surrogate operators. Furthermore, we aim to extend the framework with mixed-precision approaches, which will be implemented and analyzed. Secondly, we aim at a volume coupling of the high-performance packages waLBerla, HyTeG, and MesaPD to solve complex multiphysics problems. The coupling is done across package boundaries. This also requires more sophisticated approaches in load-balancing. Finally, the newly developed algorithms will be tested and verified with applications from geodynamics. For more information consider the job description here. Tasks Tasks in the project include
- the efficient implementation of new models, methods, and algorithms into existing high-performance frameworks,
- the fast prototyping of new ideas in individual code,
- an interest in the entire simulation pipeline: starting from simple algorithms to state-of-the-art applications in geophysics executed on supercomputers,
- as well as the presentation of the results to the scientific community in journals, at conferences, and as lecture contributions for students. Requirements We require for the position the following:
- A Ph.D. in the field of Applied Mathematics, Computer Science, Computational Science and Engineering, or similar.
- Knowledge of numerics as part of a degree program. In particular, knowledge about finite-element analysis is an absolute must. Familiarity with iterative solvers, preconditioners, multigrid methods, and mixed-precision approaches is optional but extremely useful.
- We require good programming skills and experience in C++ and its common programming idioms and design patterns. Knowledge of MATLAB, Python, Julia, or a similar scripting language is necessary for prototyping.
- Interest and affinity for high-performance computing are necessary for the position. You should have experience with the roofline model and familiarity with a profiler. Experience with GPUs is a bonus.
- Of course, you need fluency in written and spoken English to communicate your ideas in this interdisciplinary project.
- Note that we expect from candidates either a strong background in high-performance computing or in numerical analysis. If you think that you have the requirements above, you should apply for this position. We offer
- a young, dynamic, and international team of scientists from various disciplines, as well as cooperation with international partners,
- an exciting and varied project with many different aspects and possibilities for expansion,
- modern hardware and infrastructure at the workplace, from compute- and GPU servers to supercomputers,
- a salary according to the public service rates (level E13), and
- everything at a renowned and modern university in a beautiful city close to the Alps. Application Every application should include
