v2 v3 8 8 9 9 In this case a performance model encapsulates information about the software and hardware to make a prediction of elapsed wallclock run time for a given scenario. 10 11 == Shallow water model == 12 13 Annette Osprey has been developing a benchmark driven performance modelling approach to evaluate deployment choices on multi-core architectures. A shallow-water model has been benchmarked on the Cray XE6 to provide inputs to a model which is designed to predict performance on differing HPC architectures. It is hoped that this approach will provide an alternative to the expensive and time consuming testing of models by trial to find the ideal configuration of architectural parameters for best performance. The model successfully predicts the strong scaling up to 16,000 cores and has been used to choose optimal rank-core affinities. 14 15 '''Paper:''' A. Osprey, G. D. Riley, M. Manjunathaiah, and B. N.
