Maximizing utilization and minimizing migration in thermal-aware energy-efficient real-time multiprocessor scheduling 2021 Access copy available to the general public Unrestricted This work proposes CAlECs, a clustered scheduling system for MPSoCs subject to thermal and energy constraints. It calculates off-line a cyclic executive honoring temporal and thermal constraints, for a hard real-time (HRT) task set at minimum frequency to reduce consumed energy, minimizing context switches and migrations. It also provides an on-line controller able to manage system and task parametric variations and soft real-time (SRT) tasks, always meeting the HRT task set constraints and the system thermal bound. CAlECS maximizes CPU utilization to help avoid overprovisioning contributing to a low SWaP factor. Its modular design allows the utilization of different modeling and scheduling approaches, and makes the off-line and on-line components independent from each other to better suit the requirements of a specific system. We experimentally show that the cyclic executive provided by CAlECS for HRT task sets outperforms RUN, a reference off-line algorithm in terms of optimal number of context switches. info:eu-repo/grantAgreement/ES/AEI/PID2019-105660RB-C21-AEI-10.13039-501100011033 info:eu-repo/grantAgreement/ES/DGA-ESF/T58-20R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.476 2021 COMPUTER SCIENCE, INFORMATION SYSTEMS 79 / 164 = 0.482 2021 Q2 T2 TELECOMMUNICATIONS 43 / 93 = 0.462 2021 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 105 / 277 = 0.379 2021 Q2 T2 0.927 2021 Computer Science (miscellaneous) 2021 Q1 Engineering (miscellaneous) 2021 Q1 6.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Chils Trabanco, A.
