Research

I studied Physics with a major in Computer Science at Heidelberg University. For my diploma thesis I researched the potential of a port of the ALICE HLT TPC Tracker to many-core systems with wide vector units. In the course of the work I developed an abstraction for C++ for SSE and LRBni programming.

I continued research and development on the abstraction for data-parallel programming with the C++ programming language, in particular for efficient use of SIMD instructions on x86. This work was done at Frankfurt University and FIAS in collaboration with high-energy physics experiments at GSI, CERN, and RHIC.

Current Projects

  • Vc: Research and development of a C++ API for different SIMD hardware with an emphasis on developer productivity and high performance.
  • Standardization of a SIMD interface in the C++ programming language.
