Abstract: In transparent computing system, the operating systems, application programs, and users’ data are stored on the server as resources. The resources on server are loaded to the client through network and performed in the way of data block. There is a problem that users’ operating systems and application program resources are redundant on server in transparent computing. To solve the problem, this paper presents and implements a BitMap-based sharing image storage management scheme—BM-SISMS. In the scheme, system data and users’ data are separated by linkage structure. Users share the same system image by linkage structure and locate users resources by BitMap structure according to users’ request quickly. The experimental results show that, users are able to load and use the operating system normally by BM-SISMS, and BM-SISMS is able to meet the needs of storage management with high performance of reading data speed at 11.05 MB/s and writing speed at 4.01 MB/s in transparent computer system.

Key words: transparent computing, BitMap storage, linkage storage, BM-SISMS
