User-controllable parallel I/O for scientific applications
Jang Sun Lee, Youngki Song · 2002
We propose user controllable I/O operations for scientific applications in parallel computing environments and explore the effects of them with some synthetic access patterns. The operations allow users to present numerous access patterns collectively with a minimum number of I/O requests. This enables systems to aggregate bandwidth of parallel disks, optimize disk head movements, and then increase I/O performance.
