如何将qsub设置为在job1完成五秒钟后（或任何期望的值）运行job2？ [英] How to set the qsub to run job2 five seconds (or any desired value) after the job1 is finished?

问题描述

目前，我的工作是估算job1何时完成，然后使用 #PBS -a [myEstimatedTime + 5]指令为job2运行qsub，但是我对我的方法不满意，因为有时它是

Currently what I do is to estimate when job1 will be finished, then using the "#PBS -a [myEstimatedTime+5]" directive I run qsub for job2. But I’m not happy with my approach since sometimes it is over/under estimated.

有没有更好的解决方案？

Is there any better solution?

推荐答案

最好的方法是通过作业依赖项。您可以提交作业：

The best way to do this is through job dependencies. You can submit the jobs:

job1id=`qsub script1.sh`
qsub script.sh -W depend=after:$job1id

这不会它会在5秒钟后执行，但会暂停该作业（无法运行），直到第一个作业完成为止。实际上，它会在大约5秒钟后运行，因为大多数调度迭代都要花费更多的时间。

This won't make it execute 5 seconds after, but it will place a hold on the job (can't run) until after the first job finishes. In practice it will run more than about 5 seconds after because most scheduling iterations take more time than that anyway.
