My interests include a variety of subjects, such as

  • quantum field theory, in particular lattice QCD
  • random matrix theory
  • mathematical physics
  • high-performance computing
  • supercomputer design and development

If you are interested in doing a master or doctoral thesis on one of these subjects, just contact me.

I'm the principal investigator of a project in the framework of the SFB/TRR-55 in which we develop custom-designed supercomputers and high-performance software for Lattice QCD and similar applications. So far the project has delivered the following supercomputers:

  • QPACE:
    - co-design with IBM and several other companies and academic institutions
    - PowerXCell 8i processors and FPGA-based network
    - most energy-efficient supercomputer in the world in 2009/2010 (No. 1 on Green 500 list)
  • iDataCool
    - co-design with IBM
    - Intel Xeon processors and InfiniBand network
    - hot-water cooling with temperatures up to 70°C
  • QPACE 2:
    - co-design with Intel and Eurotech
    - Intel Xeon Phi (KNC) processors and network based on PCIe and InfiniBand
    - No. 15 on Green 500 list in 2015
  • QPACE 3:
    -co-design with Intel and Fujitsu
    - Intel Xeon Phi (KNL) processors and OmniPath network
    - No. 5 on Green 500 list in 2016

We are currently developing QPACE 4 in collaboration with Cray.
