SEA

The SEA code (F77) is used to model ocean circulation by solving the primitive equations of motion. The serial code was provided by D. Stevens from the University of East Anglia (UK).

Code information: 7300 lines of source and 26 subroutines

Total Parallelization Time using ParaWise : Approximately 3 hours.

User Time & Optimization : Approximately 2 hours.

The first set of results to the left show the performance of a ParaWise generated message passing code on 50 processors of a Sun Fire E25K machine using UltraSparc IV 1.05 GHz processors (RWTH Aachen University).

The second sets of results on the left show the performance of a ParaWise generated message passing code on a Compaq Alpha and on an SGI Origin 2000 (NASA Ames).
