Biography
I am Associate Professor for Computer Science at ETH Zürich where I lead the Scalable Parallel Computing Laboratory (SPCL). Before I left the USA, I was working in the Blue Waters Directorate at the University of Illinois at Urbana-Champaign. I was responsible for performance modeling and simulation of the Blue Waters Petascale computer and applications running on it. In this effort, I worked with William Kramer, Marc Snir, and Bill Gropp and external partners.
Research Interest
My research interests revolve around the central topic of "Performance-centric Software Development". In the context of High-Performance Computing (HPC), one can identify three sub-branches that I am actively working on: (1) performance modeling, simulation, and optimization of large-scale parallel applications, (2) topologies, routing, and host interfaces of large-scale networks, and (3) advanced parallel programming techniques and runtime environments. An overview graph of my past and current research activities (relative to my publication list) shows their connections:
