• ITS GPU tracking:
  • Investigating some crashes in sync mode vs not happening in async mode
• DCA fitter on GPU
  • Still trying to compile a GPU version of the library, now dealing with linking errors, even including the SMatrixGPU.h header to the compilation unit, e.g.:
  •  lld: error: undefined hidden symbol: o2::math_utils::detail::SMatrixGPU<double, 3u, 3u, o2::math_utils::detail::MatRepSymGPU<double, 3u>>::apply(unsigned int) const
>>> referenced by SMatrixGPU.h:1441 (/ssd_data/builds/latest/sw/SOURCES/O2/gpu-dca-fitter/0/Common/MathUtils/include/MathUtils/SMatrixGPU.h:1441)
