To efficiently execute a finite element program on a hypercube, we need to map nodes of the corresponding finite element graph to processors of a hypercube such that each processor has approximately the same amount of computational load and the communication among processors is minimized. If the number of nodes of a finite element graph will not be increased during the execution of a program the mapping only needs to be performed once. However, if a finite element graph is solution-adaptive, that is, the number of nodes will be increased discretely due to the refinement of some finite elements during the execution of a program, a run-time load balancing algorithm has to be performed many times in order to balance the computational load of processors while keeping the communication cost as low as possible. In this paper, we propose a parallel iterative load balancing algorithm (ILB) to deal with the load imbalancing problem of a solution-adaptive finite element program. The proposed algorithm has three properties. First, the algorithm is simple and easy to implement. Second, the execution of the algorithm is fast. Third, it guarantees that the computational load will be balanced after the execution of the algorithm
