OSTI ID:632845
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 shared memory as well. We consider how to assign processors to the major model components so as to obtain optimal load balance. We examine throughput on contemporary parallel architectures, such as the Cray-T3D/T3E and the IBM-SP family.
