Subject: W Essah,J R Davy S Openshaw Systematic Exploitation of Parallelism in Spatial Interaction Modelling

Description: This paper discusses a systematic approach to the parallel implementation of geographic applications based on Spatial Interaction Models, characterised by large requirements for both memory and computation. We show a common framework for implementing all the main components of such applications in an efficient scalable manner, gaining high speedups on a 512-processor Cray T3D. This can then used as the basis of an application generator which greatly simplifies the process of developing such systems. 1 Introduction This paper describes a systematic approach to develop efficient, scalable and portable parallel applications based on Spatial Interaction Models (SIMs) [8]. Such models are of importance to the business sector, academic researchers, and policy makers; they have been used in relation to a wide range of spatial interaction phenomena, such as movements of goods, money, services and persons, and spread of innovation. To model these interactions, large data flows are involved, to...
