PAAP: prefetch-aware admission policies for query results cache in web search engines

This article proposes to use a frequency-based cache admission policy in order to boost the effectiveness of caches subject to skewed access distributions. Given a newly accessed item and an eviction candidate from the cache, our scheme decides, based ...

On-die caches are a popular method to help hide the main memory latency. However, it is difficult to build large caches without substantially increasing their access latency, which in turn hurts performance. To overcome this difficulty, on-die caches ...

In bus-based SMPs, cache misses and bus traffic form key obstacles to high performance. To overcome these problems, several techniques have been proposed: cache prefetching, read snarfing, software-controlled updating, and cache injection for reducing ...
