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.}, keywords = {papi}, doi = {10.1109/ICPPW.2012.39}, author = {Vincent M Weaver and Matt Johnson and Kiran Kasichayanula and James Ralph and Piotr Luszczek and Dan Terpstra and Shirley Moore} } @article {icl:688, title = {PAPI-V: Performance Monitoring for Virtual Machines}, journal = {CloudTech-HPC 2012}, year = {2012}, month = {2012-09}, address = {Pittsburgh, PA}, abstract = {This paper describes extensions to the PAPI hardware counter library for virtual environments, called PAPI-V.
