| Abstract: | Difference of node machine performance and dynamic operation environment are main reasons to cause the unequal division. This paper proposes index and method of difference scaling, combines master/worker computing model with SPMD application types, and gives three kinds of load balancing algorithm. The application shows the algorithms is effective. |
