| description | This paper presents the development of a
general-purpose parallel ocean circulation model, for use on a wide range of
computer platforms, from traditional scalar machines to workstation clusters and
massively parallel processors. Parallelism is provided, as a modular option, via
high-level message-passing routines, thus hiding the technical intricacies from
the user. An initial implementation highlights that the parallel efficiency of
the model is adversely affected by a number of factors, for which optimisations
are discussed and implemented. The resulting ocean code is portable and, in
particular, allows science to be achieved on local workstations that could
otherwise only be undertaken on state-of-the-art supercomputers. |
