In particular, I am investigating two techniques to improvefile system performance: application-specific replacement policies for the filecache, and aggressive prefetching of file data from the disk. I havedeveloped a system in which the kernel allocates physical pages to individualapplications, and each application is responsible for deciding how to useits physical pages for caching and prefetching. The system uses a fairglobal allocation policy in the kernel, and carefully integrates cachereplacement, prefetching and disk scheduling. A prototype implementationon uniprocessor systems has demonstratedthat good application-chosen replacement strategies and prefetching informationcan significantly improve the I/O performance of many applications.Currently, I am extending these techniques to parallel systems. I amdeveloping integrated caching and prefetching algorithms for parallel diskarrays. In addition, I am investigating the global resource managementproblems in operating systems.<HR>Last modified: Wed Apr 24 21:38:49 1996 by Pei Cao<ADDRESS> <!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><!WA24><A HREF="http://www.cs.wisc.edu/~cao/cao.html">cao@cs.wisc.edu</A></ADDRESS></BODY></HTML>?? 快捷鍵說明
