In this paper, a parallel object collection (POC) model is introduced to support data parallelism in a parallel object-oriented system. This model is based on the idea of data partitioning and method replication. To achieve load-balancing, partition objects are dynamically migrated at runtime according to the system load situation. A threshold-based strategy is used in the dynamic load-balancing. To avoid over-convergence of load during partition object migration, a new destination node selection algorithm is proposed. The threshold values used in the algorithm are also adaptively adjusted to better reflect the fluctuation of the load during execution. To evaluate the performance of the dynamic load balancing algorithm, simulation experiments are conducted. The simulation results are reported and discussed in the paper.
