Prefetching and buffer management for parallel I/O systems
In parallel I/O systems the I/O buffer can be used to improve I/O parallelism by improving I/O latency by caching blocks to avoid repeated disk accesses for the same block, and also by buffering prefetched blocks and making ...
Competitive prefetching and buffer management for parallel I/O systems
In this thesis we study prefetching and buffer management algorithms for parallel I/O systems. Two models of lookahead, global and local, which give limited information regarding future accesses are introduced. Two ...
