We simulate the wind driven circulation in oceans. Our aim is to study the
impact of short scale wind forcing on the oceanic circulation. We use the
isopycnal version of the Spectral Element Ocean Model (SEOM). The modeling of
these flows and their climatic impact is complicated by the inherent range of
spatial scales involved, which extend from the global scale of O(10,000) km
down to the local scale of O(1) km, and by the intrinsic three dimensionality
of the dynamics.
In this talk, we define a (parallel) preconditioner that allows for a
significant speedup for problems that normally run for tens of thousands of CPU
