23 - 27 September 2019


The objective of this applied course is to provide the theoretical and technical context of terrestrial modeling in high-performance scientific computing (HPSC) environments utilizing stand-alone and coupled hydrologic, land surface and atmospheric models.
Utilizing the Terrestrial Systems Modeling Platform (TSMP), the course will take a complete tour of terrestrial modeling and HPSC in connection with real-world observations and data assimilation including

  • setting up a terrestrial model and performing simulations in massively parallel supercomputer environments at the Jülich Supercomputing Centre,
  • parallel performance analysis and profiling,
  • parallel data assimilation using TerrSysMP-PDAF (Parallel Data Assimilation Framework), and
  • post-processing and visualization in the age of big data.

Keynote Speakers

  • Lars Nerger, Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Germany
  • Michel Kern, Inria Paris Research Centre, France
  • Anne Verhoef, School of Archaeology, Geography and Environmental Sciences, University of Reading, United Kingdom
  • Stefan Kollet, Institute of Bio- and Geosciences 3, Forschungszentrum Jülich
  • Martin Schultz, Jülich Supercomputing Centre, Institute for Advanced Simulation, Forschungszentrum Jülich
  • Jens Henrik Göbbert, Jülich Supercomputing Centre, Forschungszentrum Jülich
  • Markus Geimer, Jülich Supercomputing Centre, Forschungszentrum Jülich
  • Ilya Zhukov, Jülich Supercomputing Centre, Forschungszentrum Jülich
  • Sebastian Lührs, Jülich Supercomputing Centre, Forschungszentrum Jülich
  • Plus more to be announced

Learning Outcomes

Completion of the course will provide the participants with the generic capabilities of terrestrial modeling and data assimilation in supercomputing environments with a focus on TSMP(-PDAF) including parallel performance analysis and profiling utilizing freely available software tools, and handling of very large data sets in the analyses and visualization process.

Target Audience and Prerequisites

  • Master or PhD students, PostDocs with a deep interest in terrestrial modeling (hydrology, land surface, atmosphere)
  • Basic knowledge of LINUX/UNIX and programming languages such as R, Python, C/C++, or FORTRAN as well as data formats such as NetCDF is an advantage
