The paper analyzes the dynamic balance working principles of centralized work pool, decentralized work pool and distributed work pool in the multiprocessor system. Through the simulation experiment, it brings、 forward a loosely coupled multiprocessor system using the work pool technology to assign the work tasks to the idle processors in a timely manner, which makes each machines of the loosely coupled multiprocessor system (especially for heterogeneous cluster platform) work coordinately. The speed of massive data processing is efficiently improved.
