On - Line File Caching 1
Consider the following file caching problem: in response to a sequence of requests for files, where each file has a specified size and retrieval cost, maintain a cache of files of total size at most some specified k so as to minimize the total retrieval cost. Specifically, when a requested file is not in the cache, bring it into the cache and pay the retrieval cost, and remove other files from ...

متن کاملOn Variants of File Caching
In the file caching problem, the input is a sequence of requests for files out of a slow memory. A file has two attributes, a retrieval cost and an integer size. It is required to maintain a cache of size k, bringing each file, which is not present in the cache at the time of request, from the slow memory into the cache. This incurs a cost equal to the retrieval cost of the file. Well-known spe...
متن کاملApplication-Controlled File Caching Policies
We consider how to improve the performance of le caching by allowing user-level control over le cache replacement decisions. We use two-level cache management: the kernel allocates physical pages to individual applications (allocation), and each application is responsible for deciding how to use its physical pages (replacement). Previous work on two-level memory management has focused on replac...
