Résumé :
Title: Improving Cache and Memory Performance in Multicore Architectures.

Abstract: In this talk we will present our recent work on improving the memory subsystem performance in a multi-core architecture. In particular, we will talk about techniques for improving the last-level cache performance and Memory (DRAM) performance, especially for multiprogrammed environment. First, we discuss PriSM, our Probabilistic Shared cache Management framework which provides an efficient mechanism for fine-grain management of Last-Level Cache to achieve various performance objectives such as hit-maximization, fairness or quality of service. Next we present a simple analytical model for estimating memory system performance. We validate the analytical model and discuss how it could be used for memory system design space exploration.
