| 摘 要： | 负载平衡(load balancing)是网络通信和网络并行计算中的关键问题之一. 为达到负载平衡,就必须对各节点的负载指标进行分析,给出各节点的负载值. 通过系统调用与读取硬件配置信息,实时地获取负载计算所需的参数,利用这些参数计算出复合型负载指标. 该指标经加权处理后为并行计算的进程迁移提供了更加准确的负载值.

| Abstract: | In the network communication and network paralleling computing,load balancing is one of important problems.For achieving load balancing,this paper must analyze the load index of every node and get the values of the load index.By system call and reading the hardware information of the node,this paper got the real-time parameters needed by calculating the load of the node,then calculated the value of the composite load index using these parameters.After weighted this index,more exact values of the load were supplied for the process migrating in the parallel computing. |
