Enabling accurate power profiling of HPC applications on exascale systems

Despite being one of the most important limiting factors on the road to exascale computing, power is not yet considered a "first-class citizen" among the system resources. As a result, there is no clear OS interface that exposes accurate resource power consumption to user-level runtimes that implement power-aware software algorithms.
