Abstract
We address the problem of prefetching and caching in a parallel I/O system and present a new algorithm for optimal parallel-disk scheduling. Traditional buffer management algorithms that minimize the number of I/O disk accesses, are substantially suboptimal in a parallel I/O system where multiple I/Os can proceed simultaneously.
