Implementation of modern algorithms for efficient numerical flow simulation on massively parallel computing clusters

Starting date

1 June 2021

Duration of contract

initially limited to 3 years

Remuneration

up to German TVöD 13

Type of employment

Full-time

The Institute of Aerodynamics and Flow Technology is a leading research institute in the field of aerodynamics/aeroacoustics of airplanes and aerothermodynamics of space vehicles.The main activity of the C²A²S²E department is the development of numerical methods and processes for the multi-disciplinary simulation and optimization of aircraft - from flight physics design to virtual certification. We develop physical models for complex flows and cutting-edge solution algorithms. We are also active in the development of efficient optimization strategies covering all relevant disciplines, as well as developing surrogate models based on high-fidelity methods. Customizing numerical methods for
optimal efficiency on high-performance computer clusters is of particular importance to the department.

Your tasks are the analysis and further development of a next-generation software for flow simulation, which is being developed in an international collaboration. You will analyze this software with respect to serial and parallel performance on current hardware, upgrade it for use on modern, heterogeneous HPC hardware, explore concepts for optimizing, improving, and restructuring the software, and ultimately implement these concepts within the framework of a distributed development process based on continuous integration. In addition, you will evaluate these algorithms on the basis of industrially relevant simulation scenarios. Your activities are embedded in DLR-internal as well as national andEuropean research collaboration, which are worked on by interdisciplinary teams. You will be able to present your research results at national and international conferences and publish them in relevant journals.

Your qualifications:

  • Master’s degree in computer science, computational mathematics or a comparable field of study
  • knowledge and experience in numerical methods
  • profound knowledge in software development with C or C++
  • competent working skill with Linux (as a user)
  • knowledge of parallelization standards (MPI and OpenMP)
  • interest in and basic knowledge of High-Performance Computing (HPC)
  • basic knowledge of current computer architectures
  • solid communication skills in English (written and spoken)
  • ability to work independently as well as in a team, creativity
  • previous research experience (PhD) advantageous
  • in-depth knowledge of current computer architectures for high-performance computing (HPC) desirable
  • ideally, previous knowledge of computational fluid dynamics (CFD) and experience in using industry-standard CFD solvers
  • programming experience in parallel programming with MPI and/or OpenMP desirable
  • experience with software engineering tools and tools for performance analysis and performance modeling welcome

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
