Abstract:

This paper proposes a mechanism to exploit RAM grids for disk caching based on our previous work. RAM grids for caching will organize and share the distributed free memory resources in networks, and improve the performance of the nodes with massive disk IOs~ We propose a basic scheme and autonomic col laboration mechanisms such as time distributing and space merging, which optimize the performance of our system. Finally our scheme is evaluated through  trace-based simulation.

Key words: distributed computing;RAM grid, cooperative caching, cache management, autonomic collaboration
