Georg Hager

Dr. Georg Hager is Head of Research at the Erlangen National High Performance Computing Center (NHR@FAU), Friedrich-Alexander-Universität Erlangen-Nürnberg, and an associate lecturer at the Institute of Physics, University of Greifswald. His work focuses on performance engineering, node-level optimization, and analytic modeling in high performance computing.

Research Interests:

• High Performance Computing (HPC)
• Performance Engineering and Modeling
• Architecture-Specific Optimization
• Energy Efficiency in Computing
• Scientific Code Optimization
• Execution-Cache-Memory (ECM) Model Development
• Computer Architecture for HPC

His recent publications and tutorials emphasize performance modeling, node-level engineering, hybrid programming (MPI+OpenMP), and benchmarking on modern architectures such as Ice Lake, Sapphire Rapids, and A64FX. He has contributed to the development of the LIKWID tool suite and promotes best practices in HPC education.

Scientific Awards:

• ISC Gauss Award (2018)
• Informatics Europe Curriculum Best Practices Award (2011)

Georg Hager has been instrumental in developing and teaching international tutorials on performance engineering and hybrid programming, often in collaboration with HLRS Stuttgart and TU Wien. He is the co-author of the widely used textbook Introduction to High Performance Computing for Scientists and Engineers. His work bridges theoretical modeling and practical application, aiming to improve time-to-solution and resource efficiency in large-scale scientific computing.
