DescriptionThe HPC community faces considerable constraints on power and energy of HPC installations. A standardized, vendor-neutral API for power measurement and control is needed for portable solutions to these issues at the various layers of the software stack. In this BoF, we discuss the Power API; a community standardized API for measurement and control of power/energy. The BoF will introduce newcomers to these efforts and provide clear differentiation with other ongoing projects. An interactive panel discussion with experts from involved organizations will facilitate discussions on the Power API with ample time for audience questions and comments.
