With the anticipation of exascale architectures, energy consumption is becoming one of the
critical design parameters, especially in light of the energy budget of 20–30 Megawatts set
by the US Department of Energy. Understanding an application's execution pattern and its
energy footprint is critical to improving application operation on a diverse heterogeneous
architecture. Applying application-specific performance optimization can consequently
improve energy consumption. However, this approach is only applicable to current systems …
