Unlike performance analyses, however, power and energy measurements of heterogeneous systems are difficult to conduct. Especially at the system-software level, performing power and energy measurements remains challenging. Yet, such measurements are essential to improve software components for low power and high energy-efficiency.In this paper, we analyze and discuss the power and energy 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 ways to overcome limitations (i.e., sampling constraints). To improve the current state of the art in power and energy measurements at the system-software level, we present the design and implementation of PINPOINT, an energy-profiling tool which unifies different power and energy measurement interfaces.}, language = {en} } @misc{EichlerHofmeierReifetal., author = {Eichler, Christian and Hofmeier, Henriette and Reif, Stefan and H{\"o}nig, Timo and Nolte, J{\"o}rg and Schr{\"o}der-Preikschat, Wolfgang}, title = {Neverlast: Towards the Design und Implementation of the NVM-based Everlasting Operating System}, series = {Hawaii International Conference on System Sciences 2021 - HICSS-54}, journal = {Hawaii International Conference on System Sciences 2021 - HICSS-54}, publisher = {Scholarspace}, doi = {10.24251/HICSS.2021.870}, pages = {7227 -- 7236}, language = {en} } @misc{SchmausPfeifferHoenigetal., author = {Schmaus, Florian and Pfeiffer, Nicolas and H{\"o}nig, Timo and Nolte, J{\"o}rg and Schr{\"o}der-Preikschat, Wolfgang}, title = {Nowa: A Wait-Free Continuation-Stealing Concurrency Platform}, series = {2021 IEEE International Parallel and Distributed Processing Symposium (IPDPS)}, journal = {2021 IEEE International Parallel and Distributed Processing Symposium (IPDPS)}, publisher = {IEEE}, isbn = {978-1-6654-4066-0}, doi = {10.1109/IPDPS49936.2021.00044}, pages = {360 -- 371}, language = {en} }
