A helper thread based dynamic cache partitioning scheme for multithreaded applications
Mahmut Kandemir, Taylan Yemliha, Emre Kültürsay · 2011
Focusing on the problem of how to partition the cache space given to a multithreaded application across its threads, we show that different threads of a multithreaded application can have different cache space requirements, propose a fully automated, dynamic, intra-application cache partitioning scheme targeting emerging multicores with multilayer cache hierarchies, present a comprehensive experimental analysis of the proposed scheme, and show average improvements of 17.1% and 18.6% in SPECOMP and PARSEC suites.
