Abstract: Management maneuver of load balance based on centralized system, which is operated on a machine group of Amoeba system, was studied via the comparison between the contrast experiment of task initializtion with and without task transfer strategy and the result of nonloadbalance management. Load balance maneuver has been proved to be necessary for the Distribute Computing System and can improve the performance, meanwhilethe influence of process migration on load balance was analyzed concretely. Through the whole experiment, the development pattern of load balance management applied to the Distribute Computing System as well as the reference to the better influence of process migration on load balance are presented.

Key words: distribute computing system, load balance, process migration
