GPGPU Footprint Models to Estimate Per-Core Power

We explore the problem of how to easily estimate the per-core power distribution of GPGPUs from the total power of all cores. We show that the dynamic energy consumption of a core for a given kernel, represented by its work footprint, is approximately proportional to the total time taken by all work units executing on that core, and the static power, represented by its core footprint, is propo…
