Explaining dynamic cache partitioning speed ups

Abstract — Cache Partitioning has been proposed as an inter-esting alternative to traditional eviction policies of shared cache levels in modern CMP architectures: throughput is improved at the expense of a reasonable cost. However, these new policies present different behaviors depending on the applications that are running in the architecture. In this paper, we introduce some metrics that characterize applications and allow us to give a clear and simple model to explain final throughput speed ups. I
