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 numerical experiments for important applications we show
the potential of this hybrid version, We further optimize the approach and illustrate the behavior
for larger number of nodes. Parallel I/O will be subject of future research.
