Meteorological Modelling on the DAP Series of Computers

The DAP is a massively parallel SIMD computer. The DAP 500 has 1024 processors and the DAP 600 4096 processors. The processors are connected to nearest neighbours through a 2-dimensional grid, to fast row and column highways to broadcast data and also to memory local to each processor. These connections make the DAP ideally suited to the types of computation found in Computational Fluid Dynamics and Meteorology. High speed connection to an external interface allows the real time visualisation of results, allowing numerical experimentation as a research and forecasting tool.
