| Abstract(in English) | Large-volume storage systems generally use secondary storage media such as tapes. HSM (Hierarchical Storage Management) softwares are used to keep usability for users by virtualization of secondary storages. However, we must spend times to exchange media and seek data blocks. The purpose of this study is to realize speculative staging technology. It enable to pre-load appropriate files before requests by prediction based on the history of file accesses. This paper discusses use of ICA (Indepent Component Analysis) for derivation of relationships between accessing distributed applications (tasks) and accessed files as the first approach. I examines whether ICA is applicable to the derivation by simulations based on the situation in my research center. And then, I discuss promlems obtained by the examinations. |
