Abstract

We describe our experiences with the integration of two ocean models (THCM and MOM4) within a computational framework, in this case Cactus. The use of a framework like Cactus offers many advantages to computational scientists. When integrating existing code some problems are still encountered. The main problems are structural ones caused by mismatches between data structures and parallelization models. We discuss these problems and try to offer directions for improvement of the available frameworks. Copyright © 2005 John Wiley & Sons, Ltd.
