| Abstract: | Algorithms for random-walk models of atmospheric dispersion take considerable processing time on sequential computers. Such algorithms are, however, more suited to parallel computers as they contain a high degree of parallelism. In this paper, to show this suitability and to investigate the improvement in the processing time with the use of a parallel computer, the model algorithm developed and applied in Luhar and Britter (1989, Atmospheric Environment23, 1911–1924) has been implemented on a Distributed Array of Processors (DAP). The results show a 14-fold improvement in the processing time over a sequential machine. |
