Abstract:
In this thesis, the usefulness of massively parallel computers of the MIMD class to satisfy atmospheric modellers' demands for increased computing power is examined. Algorithms to use these computers, for the dynamics, are developed for both grid-point and spectral methods. Scaling formulae for these algorithms are developed and the algorithms are implemented on the Edinburgh Concurrent Supercomputer (ECS). Another component of atmospheric models is parameterization; in which the effects of unresolved phenomenan on the mean-flow are modelled. Two parameterization schemes are implemented on the ECS and a study of the effects of load-balancing is made. Furthermore it is concluded that implementation of parameterization schemes on data-parallel computers is likely to be difficult, unlike MIMD machines where the implementation is straightforward.
