Abstract: This paper presents a data allocation strategy used in High Performance Data Processing Middleware(HPDPM) system to improve system parallelism, reduce communication costs, make the inquiry load price to be smallest, and enhance system response ability. Based on the fundamental thought and working principle of this strategy, a framework and the primary modules of the middleware system are described. This middleware system is applied to a national large engineering project.

Key words: parallel computing, database system, middleware, storage allocation
