Tobias Burnus
Tobias Burnus is a Senior Software Engineer at BayLibre's compiler-service team. His current focus is on the compiler support for OpenMP, OpenACC and GPU offloading for C, C++ and Fortran. He obtained an M.Sc. in Physics in 2004 from Free University Berlin and received 2008 a doctorate in the natural sciences (Dr. rer. nat.) from the University of Cologne; his research involved quantum-mechanical numerical calculations (DFT, CI) on molecules and solids. Tobias contributes since 2006 to the GNU Compiler Collection, initially mainly to its Fortran compiler. His interests include parallel computing, numerical calculations, parallel programming and heterogeneous programming. Tobias is a GCC maintainer for Fortran, OpenMP and OpenACC and contributes to the respective specifications.
Sessions
An update of the current status of OpenMP, OpenACC and offloading in GCC, including what has been achieved last year. A few highlights and, additionally, an outlook for next years is given of the tasks that are planned or that should be done in the near term.
Discussion of topics related to parallel computing and accelerator offloading in GCC. In particular, related to OpenMP and OpenACC and to offloading to AMD and Nvidia GPUs. But also other topics like additional offloading targets or base-language parallelization features of C, C++, Fortran, or other languages are welcome. Planned topics include completion of OpenMP 5.x and addition of more 6.x features, OpenACC extension, improving performance, but also support for a GPU kernel language (programming at the abstraction level of CUDA/HIP – as proposed for the next OpenMP version).
