OSTI ID:492009
We investigate performance of a coupled ocean/atmosphere general circulation model on high-performance computing systems. Our programming paradigm has been domain decomposition with message- passing for distributed memory. With the emergence of SMP clusters we are investigating how to best support shaped memory as well. We consider how to assign processes to the major model components so as to obtain optimal load balance. We examine throughput on contemporary parallel architectures, such as the Cray-I3D, I3B, and the IBM-SP family.
