In order to effectively deploy large-scale simulations across distributed resources, it is vital that design models be developed for design and performance prediction. Currently, many large-scale simulations are being deployed across clusters of machines. Clusters fall into two broad categorizations: homogenous and heterogenous. In homogenous clusters, resources are basically identical. For heterogeneous, resources can have great variations in structure and speciality. In this talk, we will focus on homogeneous clusters, and on hierarchical clusters, a type of heterogenous cluster. We will present and/or introduce various general design models. We will show that our models are realistic and have wide-utility in a variety of arenas: as design models, performance models, and complexity models. Moreover, our models have been validated on a number of applications across a number of engineering and computational science applications, including spin system simulations (for example for quantum chromodynamics), protein folding, numerical linear algebra (for example large-scale system solvers), tissue simulation (for example tumor growth), information retrieval, network centric operations, and social network analyses.
