针对网格系统中存在的负载平衡问题,利用物理学中的场理论,提出了一种基于计算场的网格动态负载平衡机制.该机制利用节点远程势作为负载平衡时节点选择的标准,优先选择综合性能最好的节点进行负载迁移.实验结果表明,采用本算法后的系统负载平衡指数较低,响应时间较短.同时,算法考虑了节点间的通信关系,适应性更加广泛.
A grid dynamic load balancing based on computing field is proposed,which takes the node remote potential as the standard of picking nodes in order to choose nodes with the best integration performance to do load migration.Experimental results show that the load balancing indeies are lower and the response times are shorter after applying the algorithm.At the same time,communication relations among nodes are also taken into account,which will bring it a wider adaptability.
