Caching and writeback policies in parallel file systems

Improvements in the processing speed of multiprocessors are outpacing improvements in the speed of disk hardware. Parallel disk I/O subsystems have been proposed as one way to close the gap between processor and disk speeds. Such parallel disk systems require parallel le system software to avoid performance-limiting bottlenecks. We discuss cache management techniques that can be used in a parallel le system implementation. We examine several writeback policies, and give results of experiments that test their performance.
