SUMMARY:Combining CUDA and SYCL for Accelerating Earthquake Simulations in
  SeisSol
DESCRIPTION:Minisymposium\n\nRavil Dorozhinskii and Michael Bader (Technic
 al University of Munich) and Alice Gabriel (Scripps Institution of Oceanog
 raphy)\n\nSeisSol is a high-performance simulation package designed for la
 rge-scale simulations of earthquakes and seismic phenomena. SeisSol is bas
 ed on the discontinuous Galerkin method, the ADER time integration and Loc
 al Time Stepping. SeisSol uses a custom Domain Specific Language, called Y
 ATeTo, to tackle the demand of modeling various wave propagation models as
  well as providing portability between various CPU and GPU architectures f
 rom different vendors which have different capabilities and limitations. I
 n this talk, we are going to report on 1) our recent results obtained with
  the SYCL compiler backend of YATeTo, 2) discuss benefits of using SYCL in
 stead of OpenMP in the implementation of the dynamic rupture model in Seis
 Sol and thus 3) coupling CUDA/HIP GPU programming models with SYCL.\n\nDom
