Objectives

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.
