The Design, Implementation, and Performance of a Parallel Ocean Circulation Model
We describe new parallelization techniques applied to a highly parallel ocean circulation application code -- the Miami Isopycnic Ocean Coordinate Model or MICOM. We compare three parallel architectures executing MICOM: vector, massively parallel, and a multiprocessor workstation. Results from a hig...
