摘      要：Improved modelling of ice sheets, by use of high resolution and with representation of inert physical processes, is constrained by long run-times even on the latest single-processor workstation. Parallel processing therefore has a role to play. This paper describes techniques for the parallel processing of ice sheet models and presents design approaches for both the Gray T3 series and other parallel architectures. An implementation of a fully coupled, thermodynamic, 3D ice sheet model is described for the Gray T3D and is shown to be scaleable and efficient. (C) 2001 Elsevier Science Ltd. All rights reserved.
