Dynamic Load Balancing for Ocean Circulation Model with Adaptive Meshing

This paper reports the parallel implementation of adaptive mesh reenement within nite diierence ocean circulation models. The implementation is based on the model of Malleable Tasks with ineeciency factor which allows a simple expression of the diierent levels of paral-lelism with a good eeciency. Our goal within this work was to validate this approach on an actual application. For that, we have implemented a load-balancing strategy based on the well-known level-by-level mapping. Preliminary experiments are discussed at the end of the paper.
