Storage scheduling method and system, job scheduling method and system and management node

Abstract

The invention provides a storage scheduling method and a job scheduling method for scheduling according to a path available bandwidth, and further provides a management node, a storage scheduling system and a job scheduling system corresponding to the storage scheduling method and the job scheduling method. According to the storage scheduling algorithm, a data block is stored in a data node list with the maximum weighted mean of the path available bandwidth, network blocking is avoided, and the network transmission time of storage of the data block is shortened. Distribution optimization operation of data nodes is processed according to the path available bandwidth information, the localization probability of operation is improved, and the total completion time of operation is shortened.
本发明提出了一种根据路径可用带宽进行调度的存储调度方法和作业调度方法,还提出了与之相对应的管理节点、存储调度系统和作业调度系统。本发明根据存储调度算法将数据块存储在路径可用带宽加权均值最大的数据节点列表,避免了网络拥塞并缩短了数据块存储的网络传输时间。本发明根据路径可用带宽信息为数据节点分配优选作业进行处理,提升了作业的本地化概率,并且减少了作业总完成时间。
