Abstract

This report is a documentation of the techniques applied for making a parallel version of the sigma-coordinate ocean model due to Berntsen, Skogen and Espelid [2], with recent modifications given by Berntsen [1]. Results are given for a quadratic and constant depth closed basin and the North Sea, both with 20 km and 4 km horizontal resolution, and the speedups obtained are discussed.
