摘要:

并行应用程序向生产超级计算机系统的作业提交必须根据作业提交参数进行仔细调整,以获得最小的响应时间。在这项工作中,我们已经开发了一个端到端的资源管理框架,使用队列等待和执行时间的预测,以尽量减少响应时间提交给超级计算机系统的用户作业。我们的方法预测队列等待时间自适应地选择预测方法的基础上集群结构的类似的工作。我们的执行时间预测策略动态地学习负载对执行时间的影响,并使用它来预测目标作业的一组执行时间范围。我们已经开发了两种资源管理技术,采用这些预测,一个选择的处理器的数量执行和其他也动态地改变作业提交时间。使用大型超级计算机跟踪的工作负载模拟,我们显示了大规模的改进,在预测和减少响应时间在现有的技术和基线策略。

英文摘要:

Job submissions of parallel applications to production supercomputer systems will have to be carefully tuned in terms of the job submission parameters to obtain minimum response times. In this work, we have developed an end-to-end resource management framework that uses predictions of queue waiting and execution times to minimize response times of user jobs submitted to supercomputer systems. Our method for predicting queue waiting times adaptively chooses a prediction method based on the cluster structure of similar jobs. Our strategy for execution time predictions dynamically learns the impact of load on execution times and uses this to predict a set of execution time ranges for the target job. We have developed two resource management techniques that employ these predictions, one that selects the number of processors for execution and the other that also dynamically changes the job submission time. Using workload simulations of large supercomputer traces, we show large-scale improvements in predictions and reductions in response times over existing techniques and baseline strategies.
