SUMMARY:Pinpoint the Joules: Unifying Runtime-Support for Energy Measureme
 nts on Heterogeneous Systems
DESCRIPTION:Workshop\n\nPinpoint the Joules: Unifying Runtime-Support for 
 Energy Measurements on Heterogeneous Systems\n\nKöhler, Herzog, Hönig, Wen
 zel, Plauth...\n\nFor the design and operation of today's computer systems
 , power and energy requirements are highest priorities. Unlike performance
  analyses, however, power and energy measurements of heterogeneous systems
  are difficult to conduct. Especially at the system-software level, perfor
 ming power and energy measurements remains challenging. Yet, such measurem
 ents are essential to improve software components for low power and high e
 nergy efficiency.\n\nIn this paper, we analyze and discuss the power and e
 nergy characteristics of several heterogeneous systems with up to 20 cores
  (160 hardware threads) and 1 TB of main memory. For the analyzed systems,
  we outline challenges regarding power and energy measurements and show wa
 ys to overcome limitations (i.e., sampling constraints). To improve the cu
 rrent state of the art in power and energy measurements at the system-soft
 ware level, we present the design and implementation of PINPOINT, an energ
 y-profiling tool which unifies different power and energy measurement inte
 rfaces.\n\nTag: System Software and Runtime Systems\n\nRegistration Catego
