Forschungszentrum Jülich GmbH
Earth and Space Science Informatics (ESSI)
Ocean Sciences (OS)
The Jülich Supercomputing Centre (JSC) operates one of the most powerful HPC infrastructures in Europe, enabling scientists and engineers to solve highly complex problems by simulations. Earth System Modelling (ESM) has been heavily reliant on HPC for decades. The societal challenges related to climate change have never been more obvious and urgent than today. To keep ESM code developments synchronized with the rapidly evolving HPC landscape, JSC has established two Simulation and Data Laboratories (SDLs) Climate Science and Terrestrial Systems tasked with bridging the modelling communities to the HPC infrastructure. To benefit from the current and upcoming heterogeneous exascale HPC-architectures, porting, optimizing, and refactoring ESM codes is a continuous task. As part of the German ESM strategy a national ESM support team is funded by BMBF. The team members will be located at DKRZ ( https://www.dkrz.de/en/about-en/vacancies/vacancies ) and at JSCs SDLs Climate Science ( https://www.fz-juelich.de/ias/jsc/slcs ) and Terrestrial Systems ( https://www.fz-juelich.de/ias/jsc/slts ).
The ESM support team will be tasked with optimising resources, promoting synergies, sharing insights and disseminating knowledge. While the individual scientific code development is done at the Earth system science research institutions, the technical challenges related to HPC, modularization, and coupling are often similar and will be coordinated by the ESM team. Typical tasks expected of the successful candidate(s) include:
- Devising and implementing strategies together with the ESM domain scientists to address the technical and infrastructure challenges posed in order that their codes can make effective use of current and future HPC-systems.
- Algorithmic refactoring, optimisation and support of ESM community codes on contemporary HPC systems.
- Facilitating and supporting the transfer of HPC and workflow expertise to the domain scientists as part of each collaboration.
- Opportunity to spend periods working on ESM codes directly at the host institutions within a collaboration.
- Identification of synergies and potential know-how transfer of ESM and HPC-related expertise between projects.
- Co-organisation of dedicated HPC training programmes for the ESM community.
- A university degree (PhD or Master with some working experience) in Computer Science, Applied Mathematics, Computational Physics/Engineering or related fields with strong relation to scientific computing
- Experience and interest in geoscientific applications (meteorology, oceanography, terrestrial systems) is an advantage
- Experience and strong interest in some area of High Performance Computing, such as – Hybrid programing models for heterogeneous HPC architectures, MPI/OpenMP – Programming for GPUs (with CUDA or OpenACC) – Environments for and operation of highly scalable applications
- Strong programming and modern software engineering skills like – C/C++ and/or Fortran – Fluent handling of UNIX/LINUX and scripting languages
- Fluent in spoken and written English
- Self-motivated personality, with the ability to work within a multi-disciplinary team and environment on challenging problems
