摘要: Dynamic reconfiguration is the ability to modify a parallel or distributed system while it running. We adopt framework developed by Kramer et al. (1985) at architecture level: changes must occur in consistent state, which brought about "freezing" some components. The goal reduce disruption, i.e., minimize: part of be "frozen"; and time taken operations. Towards first we take connection based approach instead component one. To time, refine algorithm executing as much possible. Our model also handles hierarchic systems.
