该文主要研究主动自调度集群的调度策略和算法。传统的集群系统是前端分发器的基于负载的平衡来分发任务,ASAS集群系统采用了基于后端服务器负载分析后的主动调度策略,整个过程是基于负载动态反馈的。实验证明,该调度策略取得了比一般集群调度策略更优的效果。
This paper mainly studies the scheduling strategy and algorithm of active self-scheduling cluster. The traditional cluster system distributes the load based on the balance of the front-end distributor. The ASAS cluster system adopts the active scheduling strategy based on back-end server load analysis. The whole process is based on dynamic load feedback. Experiments show that the scheduling strategy has better performance than the general scheduling strategy.
