Why or why not?\u003Cbr \/\u003E \u003Cbr \/\u003ETo answer these questions, we posit a simple strawman model of the energy to execute an algorithm. Our model is the energy-based analogue of the time-based \u0022roofline\u0022 model of Williams, Patterson, and Waterman (Comm. ACM, 2009). What do these models imply for algorithm design? What might computer architects tell algorithm designers to help them better understand whether and how algorithm design should change in an energy-constrained computing environment?\u003Cbr \/\u003E \u003Cbr \/\u003ENote: This talk is about an idea, rather than a well-developed set of results.
