Brief Abstract: There are a number of challenges facing the High Performance Computing (HPC) community, including vastly increasing levels of concurrency, deeper and more complex memory hierarchies, mixed hardware sets and increasing scale. Assessing not only the achieved, but also, the potential, performance of complex scientific applications on such high-performance computing architectures is difficult.

In this talk, we present the results of a three year collaboration between the United Kingdom's Atomic Weapons Establishment (AWE) and the University of Warwick (UK) in developing both simulation and analytically-derived models of performance for the assessment of existing and future computing platforms. Specifically, we elaborate on the use of performance models at AWE to assess machine selection, software stack upgrades, code/algorithm optimisation and 'optioneering' for future platform strategies.
