Abstract

We analyze energy efficiency of a 3D coastal ocean simulator on Haswell and Cortex-A15 architectures and propose a simple yet effective way to model energy-to-solution on different hardware platforms. The work also demonstrates that using processors from the field of embedded/mobile computing can increase the energy efficiency by 50 %.
