-aging blocks in a cache hierarchy by deciding where in the hierarchy an incoming block should be placed. Our technique makes decisions by adapting to the access patterns of differ-ent blocks. The contributions of this paper are fourfold. First, we motivate our solution by demonstrating the importance of a

This paper studies the “filter effects ” that occur in Web proxy caching hierarchies due to the presence of multiple levels of caches. That is, the presence of one level of cache changes the structural characteristics of the workload presented to the next level of cache, since only the requests

The rapid growth of the Web has sparked significant research activity on improving the performance and scalability of the Web. Much of this work focuses on Web caching: client-side caching, server-side caching, proxy-level caching, and multilevel caching hierarchies. Single-level caching and multi

dynamic to leakage energy. Leakage energy is of particular concern in dense cache memories that form a major portion of the transistor budget. In this work, we present several architectural techniques that exploit the data duplication across the different levels of cache hierarchy. Specifically, we employ

The cache hierarchy of state-of-the-art—especially multicore—microprocessors consumes a significant amount of area and energy. A significant amount of research has been devoted especially to reducing the latter. One of the most important microarchitectural techniques proposed for the energy

This paper uses trace-driven simulation and synthetic Web workloads to study the request arrival process at each level of a simple Web proxy caching hierarchy. The simulation results show that a Web cache reduces both the peak and the mean request arrival rate for Web traffic workloads. However

dynamic to leakage energy. In fact, leakage energy is projected to become the dominant portion of the chip power budget for 0.10 micron technology and below. Leakage energy is of particular concern in dense cache memories that form a major portion of the transistor budget.

Evaluating application vulnerability to soft

Memory hierarchy performance, specifically cache memory capacity, is a constraining factor in the performance of modern computers. This paper presents the results of twolevel cache memory simulations and examines the impact of exclusive caching on system performance. Exclusive caching enables

This paper uses trace-driven simulations to evaluate the performance of three different cache management techniques for multi-level Web caching hierarchies. In particular, the experiments consider heterogeneous cache replacement policies, size-based partitioning, and sharingbased partitioning
