Exposing I/O Concurrency with Informed Prefetching
Informed prefetching provides a simple mechanism for I/O-intensive, cache-ineffective applications to efficiently exploit highly-parallel I/O subsystems such as disk arrays. This mechanism, dynamic disclosure of future accesses, yields substantial benefits over sequential readahead mechanisms found in current file systems for non-sequential workloads. This paper reports the performance of the Transparent Informed Prefetching system (TIP), a minimal prototype implemented in a Mach 3.0 system with up to
