Beschreibung

The School of Computation, Information and Technology at the Technical University of Munich (TUM)

Postdoctoral Researcher in numerical mathematics / computer science (M/F/d, 100%)

The BMBF-funded position is located within the research project
Multiphysics simulations for geodynamics on heterogeneous exascale systemsat the Chair of Numerical Analysis, led by Prof.

Dr. Barbara Wohlmuth in the TUM Department of Mathematics. We seek a postdoctoral researcher, with starting date as soon as possible.

This is a 100% position at German Civil Service salary level TV-L E13, and is financed initially until October 2025 with a possibility of extension.

The position carries no teaching load.

Project Summary

The research project
Multiphysics simulations for geodynamics on heterogeneous exascale systemsis a multidisciplinary project combining the fields of mathematics, computer science, geophysics, and high-performance computing.

Each field is represented by a dedicated project partner, which brings in their experience.

These are the Chair of Numerical Analysis at TUM, the Chair of System Simulation at FAU Erlangen, the Chair of Geophysics at LMU München, and finally, the LRZ Garching with their knowledge about supercomputers.

Firstly, the project 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.

Tasksin the project include
