Highly parallel computers have the memory capacity and potential speed to perform very high-resolution time-dependent calculations. Parallel computers with hundreds of fast processors require highly scalable algorithms to avoid wasting expensive resources. On these machines careful attention must be given to program design to fully exploit scalable algorithms. We have proposed a programming model...
A two-pronged effort to convert a recently developed ocean circulation model written in Fortran-77 for execution on massively parallel computers is described. A data-parallel version was developed for the CM-5 manufactured by Thinking Machines, Inc., while a message-passing version was developed for both the Cray T3D and the Silicon Graphics ONYX workstation. Since the time differentiation scheme...
