Client-side file caching has long been recognized as a file system enhancement to reduce the amount of data transfer between application processes and I/O servers. However, caching also introduces cache coherence problems when a file is simultaneously accessed by multiple processes. Existing coherence controls tend to treat the client processes independently and ignore the aggregate I/O access pattern. This causes a serious performance degradation for parallel I/O applications.
