The aim of the project was to extend the scalability and parallelization strategy of SimuCoast code to enable the use of hybrid CPU+GPU supercomputers. The code is focused on increasing the understanding of coastal processes utilizing high performance computing (HPC) for the numerical simulation of the three-dimensional turbulent flow, which is induced in the coastal zone, and mainly in the surf zone, by wave propagation (oblique to the shore), refraction, breaking and dissipation.
