Game-changing computational engineering technology

Abstract : During the last two decades, giant strides have been achieved in many aspects of computational engineering. Higher-fidelity mathematical models, better approximation methods, and faster algorithms have been developed for many engineering applications. Coarse-grain and fine-grain SIMD, SPMD, and MIMD parallel processors have come and gone, like the wind. Linux clusters are now ubiquitous, cores have replaced CEs, and GPUs have shattered computing speed barriers. Most importantly, the potential of high-fidelity physics-based simulations for providing deeper understanding of complex engineering systems and enhancing their performance has been recognized in almost every field of engineering. Yet in many applications, high-fidelity numerical simulations remain so computationally intensive that they cannot be used as often as needed, or are more often used in special circumstances than routinely. Consequently, the impact of computational engineering sciences on time-critical operations such as design, design optimization, and control has not yet fully materialized. Exascale computing alone is unlikely to make this happen. Achieving this objective demands instead a game-changing computational technology that bridges both ends of the computing spectrum: big iron and online computing. This talk will argue for this pressing need, and discuss recent trends in model order reduction that are likely poised to change the landscape of computational engineering.
