摘要 在XML多核查询中,如果任务分配不均衡,各个核之间在完成处理时间上会产生较大差异,从而影响了最终结果的构建。本文针对XML多核查询中负载不均衡的情况,探讨了任务抢占策略在XML多核查询中的应用,分析并总结了现有的框架,提出了一种任务抢占策略。 If the task is not balance in the XML multi-core query process,the time will be long for the construction of the result,because the time depends on the longest time.This paper focuses on the imbalance condition of workload and discusses the strategy of task preemption in XML multi-core query.It also analyzes and summarizes the existing framework,and proposes a strategy of task preemption.
