We have extended the Performance API (PAPI) analysis library to measure and report energy and power values. These values are reported using the existing PAPI API, allowing code previously instrumented for performance counters to also measure power and energy. Higher level tools that build on PAPI will automatically gain support for power and energy readings when used with the newest version of PAPI. We describe in detail the types of energy and power readings available through PAPI. We support external power meters, as well as values provided internally by recent CPUs and GPUs. Measurements are provided directly to the instrumented process, allowing immediate code analysis in real time. We provide examples showing results that can be obtained with our infrastructure. %B International Workshop on Power-Aware Systems and Architectures %C Pittsburgh, PA %8 2012-09 %G eng %R 10.1109/ICPPW.2012.39 %0 Journal Article %J SAAHPC '12 (Best Paper Award) %D 2012 %T Power Aware Computing on GPUs %A Kiran Kasichayanula %A Dan Terpstra %A Piotr Luszczek %A Stanimire Tomov %A Shirley Moore %A Gregory D.
