A hybrid SWAN version for fast and efficient practical wave modelling
Publication

In the Netherlands, for coastal and inland water applications, wave modelling with SWAN has
become a main ingredient. However, computational times are relatively high. Therefore we
investigated the parallel efficiency of the current MPI and OpenMP versions of SWAN. The
MPI version is not that efficient as the OpenMP version within a single node. Therefore, in this
paper we propose a hybrid version of SWAN. It combines the efficiency of the current OpenMP
version on shared memory with the capability of the current MPI version to distribute memory
over nodes. We describe the numerical algorithm. With initial numerical experiments we show
the potential of this hybrid version. Parallel I/O, further optimization, and behavior for larger
number of nodes will be subject of future research.
