Dynamic Load Balancing for Adaptive Mesh Ocean Circulation Model
Éric Blayo, Laurent Debreu, Grégory Mounié, Denis Trystram · 2000
This paper reports the parallel implementation of adaptive mesh refinement within finite difference ocean circulation models. The implementation is based on the model of Malleable Tasks with inefficiency factor which allows a simple expression of the different levels of parallelism with a good efficiency. 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.
