I am Assistant Professor for Computer
Science at ETH Zürich where I lead the Scalable Parallel Computing Laboratory
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.
I am co-chair of the collective
operations working group in the MPI Forum. I am interested in Collective Communications, Process Topologies, One
Sided Operations, and Hybrid Programming in MPI. I am also a member of ACM SIGHPC, ACM, and IEEE.
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: Research Overview.
My Erdős number is three (via Marc Snir and Shlomo Moran) and
I am an academic descendant of Hermann von Helmholtz.
