Integrated Parallel Prefetching and Caching
Prefetching and caching are widely-used approaches for improving the performance of le systems. A recent study shows that it is important to integrate the two, and proposed an algorithm that performs well both in theory and in practice [2, 1]. That study was restricted to the case of a single disk. Here, we study integrated prefetching and caching strategies for multiple disks. The interaction ...
متن کاملEnergy Efficient Prefetching and Caching
Traditional disk management strategies—prefetching and caching in particular—are designed to maximize performance. In mobile systems they conflict with strategies that attempt to save energy by powering down the disk when it is idle. We present new rules for prefetching and caching that maximize power-down opportunities (without performance loss) by creating an access pattern characterized by i...
متن کاملIntegrated Parallel Prefetching and Caching
Recently there has been a great deal of interest in prefetching from parallel disks, as a technique for enabling serial applications to improve I/O performance. Studies have also shown that for optimal performance, it is important to properly integrate prefetching and caching. In this paper, we study integrated prefetching and caching strategies for multiple disks. We present two algorithms, re...
متن کاملCaching and Prefetching for Web Content Distribution1
Proxy caching is an effective technique to reduce the network resources consumed by web services as well as the access latencies perceived by web users. This article discusses the issues and challenges of deploying web caching proxies over the Internet. We focus on the cache management for conventional web objects such as HTML pages and images and present the state-of-the-art solutions to vario...
متن کاملReal-time integrated prefetching and caching
The high latencies for access to background memory like hard disks or flash memory can be reduced by caching or hidden by prefetching. We consider the problem of scheduling the resulting I/Os when the available fast cache memory is limited and when we have real-time constraints where for each requested data block we are given a time interval during which this block needs to be in main memory. W...
