摘要
异构环境下"集群系统"负载均衡技术的关键是实现进程的跨平台迁移,对于进程的跨平台迁移所带来的困难和开销是巨大的。在传统进程迁移算法基础上,充分考虑节点对提交作业的适应性,提出一种新的TL-Scheduling负载均衡算法,能够控制作业提交到适合它执行的节点上,该算法可以有效提高系统负载均衡和作业执行效率。在其基础上,研究设计了基于XML业务流程模板的卫星作业调度系统,使得作业调度系统更加实用化。
In the heterogeneous cluster environment, the main method for load balance is to actualize the migration of process. The difficulties and cost are tremendous in the process migration. Based on traditional process migration algorithm, a TL_Scheduling load balance algorithm is presented, which consider the adaptability of submitted jobs to the node, and can control jobs to run on the most adaptive node. The algorithm can improve the load of system and the efficiency of running job. Based on the algorithm, a job-scheduling system based on XML flow template is proposed. This function makes this job-scheduling system more practical.
