OFFER DESCRIPTION

Work group:

JSC - Jülich Supercomputing Centre

Area of research:

Scientific / postdoctoral posts

Job description:

Supercomputers help us find solutions to major scientific challenges and are indispensable for modern research. The Jülich Supercomputing Centre (JSC) operates the most powerful computer systems for scientific and technical applications in Europe and makes it available for research purposes to scientists at Forschungszentrum Jülich, in Germany, and throughout Europe. JSC performs various research and development tasks, frequently in tight cooperation with national and international partners. The DEEP-SEA and IO-SEA projects are funded by the European Commission as part of the Euro HPC initiative. They will deliver the programming and data flow environment for future European exascale systems, adapting all levels of the software stack—including low-level drivers, computation and communication libraries, IO, resource management, and programming abstractions with associated runtime systems and tools—to support highly heterogeneous compute, memory, and storage configurations. A core strategy of DEEP- and IO-SEA is that all these elements are co-designed in concert with important European research codes. The Terrestrial Systems Modelling Platform (TSMP) for regional Earth system modelling ( www.terrsysmp.org ) is the only application participating in both projects, and will be one of the first exascale-ready codes. TSMP is a physically-based representation of water, energy and momentum transport across scales down to sub-km resolution including explicit feedbacks between groundwater, the land surface and atmosphere with a focus on the terrestrial hydrological and energy cycles. TSMP is developed and maintained at the Simulation and Data Lab Terrestrial Systems at JSC in close collaboration with the Institute of Bio and Geosciences (IBG-3) and the Geoverbund ABC-J. TSMP will help guide the co-design of the next generation of HPC software stacks and I/O strategies for exascale computing, ensuring its applicability in the next generation of supercomputers.

Your Job:

  • Implement novel programming models and I/O strategies to enable an exascale-ready TSMP based on the developments from various teams within DEEP- and IO-SEA.
  • Perform model profiling of computation, memory, communication and I/O performance (including the complete data workflow) of TSMP under real application conditions.
  • Contribute to establishing TSMP’s requirements for exascale computing software stacks, programming models, data storage and staging models.
  • Participate in the development of TSMP’s heterogeneous and modular computing development strategy towards exascale scaling in collaboration with the team of the Simulation and Data Lab Terrestrial Systems.
  • Communicate with the teams participating in co-design of exascale software stacks.
  • Perform and analyse demonstration simulations with TSMP in the context of DEEP- and IO-SEA exascale performance goals.
  • Writing internal project reports and scientific publications.

Your Profile:

  • A Master and PhD degree (or equivalent degrees and experience) in one or more of the following disciplines: hydrology, climate science, computer science, environmental science, geosciences.
  • Experience and interests in HPC and modelling, preferably in Earth system
  • Experience with TSMP and/or its model components (COSMO, Parflow, CLM, PDAF) and coupler (OASIS) is of significant advantage
  • Experience with heterogeneous computing platforms (e.g., GPUs) is of clear advantage
  • Fluent in written and spoken English
