Papaefstathiou, E., Kerbyson, D.J. and Nudd, G.R. (1994) A layered approach to parallel software performance prediction: a case study. Technical Report. Department of Computer Science, Coventry, UK.
Abstract
An approach to the characterisation of parallel systems using a structured layered methodology is described here. The aim of this is to produce accurate performance predictions which maybe used to influence the choice of machines and investigate implementation trade-offs. The methodology described enables the separate characterisation of both application, and parallel machine to be developed independently but integrated through an intermediary layer encompassing mapping and parallelisation techniques. The layered approach enables characterisations which are modular, re-usable, and can be evaluated using analytical techniques. The approach is based upon methods introduced in Software Performance Engineering (SPE) and structural model decomposition but due to its modular nature, takes less time for development. A case study in image synthesis is considered in which factors from both the application and parallel system are investigated, including the accuracy of predictions, the parallelisation strategy, and scaling behaviour.
