A Framework for Adaptive Storage Input/Output on Computational Grids

摘要

Emerging computational grids consist of distributed ocllections of heterogeneous sequential and parallel systems and irregular applications with complex,data dependent execution behavior and time varying resource demands. TO provide adaptive input/output resource management for these systems, we are developing PPFS II, a portable parallel file system. PPFS II suports rule-based, closed loop and interactive control of input/output subsystems on both parallel and wide area distributed systems.
