Scientific Computing Center (SCC)

Ihre Aufgaben

-----------------


The Scientific Computing Center is the Information Technology Center of KIT.


Earth system models (ESMs) are highly complex software systems that have often developed over several decades. In addition to the core model that computes meteorological processes, an ESM includes a wide range of specialized submodels - such as those for cloud microphysics or atmospheric chemistry - interconnected through well-defined interfaces. The computational demands of ESMs are immense, but their high degree of parallelism enables long-term climate simulations on modern HPC clusters. Continuously adapting these models to the latest hardware and software developments remains an ongoing challenge.


Your responsibilities in this area will include the following tasks (in close collaboration with domain scientists):

Ensuring the sustainability of community ESM codes, and enabling the adoption of modern HPC systems Enabling and improving high-performance computing capabilities of ESM codes, including performance optimization Contributing to porting ESM codes to heterogeneous HPC architectures, including GPU-accelerated systems Participation in model developments with regard to the further development of an improved simulation of the Earth system Participate in the NHR ESM community through software development support and user outreach Carrying out own research in atmospheric modeling, including running and analyzing ESM simulations Participating in scientific conferences and contributing to peer-reviewed publications
