ReD: A reuse detector for content selection in exclusive shared last-level caches 2019 Access copy available to the general public Unrestricted The reference stream reaching a chip multiprocessor Shared Last-Level Cache (SLLC) shows poor temporal locality, making conventional cache management policies inefficient. Few proposals address this problem for exclusive caches. In this paper, we propose the Reuse Detector (ReD), a new content selection mechanism for exclusive hierarchies that leverages reuse locality at the SLLC, a property that states that blocks referenced more than once are more likely to be accessed in the near future. Being placed between each L2 private cache and the SLLC, ReD prevents the insertion of blocks without reuse into the SLLC. It is designed to overcome problems affecting similar recent mechanisms (low accuracy, reduced visibility window and detector thrashing). ReD improves performance over other state-of-the-art proposals (CHAR, Reuse Cache and EAF cache). Compared with the baseline system with no content selection, it reduces the SLLC miss rate (MPI) by 10.1% and increases harmonic IPC by 9.5%. info:eu-repo/grantAgreement/ES/DGA/T58-17R info:eu-repo/grantAgreement/ES/MINECO/TIN2014-52608-REDC info:eu-repo/grantAgreement/ES/MINECO/TIN2015-65316-P info:eu-repo/grantAgreement/ES/MINECO/TIN2016-76635-C2-1-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.296 2019 0.525 2019 COMPUTER SCIENCE, THEORY & METHODS 35 / 108 = 0.324 2019 Q2 T1 Artificial Intelligence 2019 Q2 Computer Networks and Communications 2019 Q2 Hardware and Architecture 2019 Q2 Software 2019 Q2 Theoretical Computer Science 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Monreal, T.
