Description:"One of the most severe constraints in semi-implicit modeling is related to the requirement of solution of a system of Helmholtz equations. The usual method of solution by relaxation methods requires large horizontal fields of data in the computer core storage at one time, while other parts of the computation are more conveniently performed on vertical strips of data. This dual form of data use leads to inefficiencies in data access and greater wall clock times for forecast programs"--Page 1.
