Torsten Wilde is a research associate at the Leibniz Supercomputing Centre (LRZ), Germany. He received his M.Sc. degree in "Parallel and Scientific computation" from the University of Liverpool, UK, in 2000, and a Dipl.-Ing. (FH) in "Technische Informatik" from the University of Applied Sciences in Berlin, Germany. He is currently responsible for LRZ's research activities on energy efficient HPC data center design and operation. In this role, Torsten is working on methods of improving energy efficiency across the whole data center, ranging from data center infrastructure to application scheduling. He is a team member of the energy efficiency task force at LRZ, a member of the Energy Efficient High Performance Computing Working Group (EEHPC WG), a member of the Association for Computing Machinery (ACM), and was the work package lead for the energy efficient HPC prototyping efforts during the Partnership for Advanced Computing in Europe (PRACE) 1st and 2nd implementation phase projects. He is currently leading the SIMOPEK project (www.simopek.de) which aims to model, simulate, and optimize the W4 chiller-less cooling infrastructure of the LRZ data center. His background is in scientific visualization and steering, component architecture for high performance computing, business workflow system design, and multi-system data collection and analysis.
