Implementation of an Eta Belt Domain
on Parallel Systems
Jules Kouatchou, Miodrag Rancic, Peter Norris and Jim Geiger
We extend the Eta weather model from a regional domain into a
belt domain that does not require meridional boundary conditions.
We describe how the extension is achieved and the parallel implementation
of the code on the Cray T3E and the SGI Origin 2000. We validate
the forecast results on the two platforms and examine how the
removal of the meridional boundary conditions affects these forecasts.
In addition, using several domains of different sizes and resolutions,
we present the scaling performance of the code on both systems.
