Performance Prediction and Ranking of Supercomputers

Performance prediction asks how much time executing an application is likely to take on a particular machine. Machine ranking asks which of a set of machines is likely to execute an application most quickly. These two questions are discussed within the context of large parallel applications run on supercomputers. Different techniques are surveyed, including a framework for a general approach that weights the results of machine benchmarks run on all systems of interest. Variations within the framework are described and tested on data from large-scale applications run
