Parallel Cache Model Based on Grid Memory

For supporting the concurrent access for the hot segments of large files during the peak access phase in Internet, a parallel cache model based on the grid memory (PCMGM) was proposed in this paper. By using of the free memories of the idle computers in dynamic network environment (DNE) composed of multi-clusters, the grid memory was constructed. Through the division technique for large files, basing the ability of idle computer, and adopting the multiagent, we discussed the load balance allotting approach for grid memory. The PCMGM access process is described. The experiment results show that PCMGM resolves effectively the problems of peak access for hot segments and it can improve the use rate of resources in DNE. It can be applied for grid computing and VOD for hot segment.
