Novel Shared Cache Dynamic Partition Mechanism
Zhou Xiao-fang · Jisuanji gongcheng · 2011
By full using advantages of Utility-based Cache Partition(UCP) and Least-recently Used(LRU) policy,a new dynamic shared cache partitioning mechanism is presented.The proposed mechanism is called Improved Utility-based And least-recently used Cache Partition(IUL-CP).It reduces the pollution of multi-threads in the shared cache and resolves the low performance when all cores running the shared cache way number sensitive workloads in multi-core systems with the UCP mechanism.The evaluation,by running SPEC CPU2000 benchmarks,shows that IUL-CP improves the performance by 20.28% over LRU and 14.37% over UCP on average.
