Load balance for network parallel computing

The principle of the dynamic load balance for a distributed system was used to design a preemptive dynamic load balancing architecture to meet requirements of the network distributed and parallel computing environment. A centralized information system was introduced to collect all process's information. A hybrid transmission control method of combining centralized and distributed logic was described based on the process migrating. A new load index was particularly defined for the case to make sure a processor's load level. The corresponding theoretic analysis for the important problems in implementation was discussed. The critical strategies and algorithms were presented. The results of the simulation show that the architecture and related strategies can provide effectively support to the network parallel computing.
