PBS不断中止我的工作

我要求一个(每个有32个)14个处理器,如下所示:

#PBS -l nodes=1:ppn=14

#PBS -l walltime=12:00:00

ppn它几乎总是有效,但是一旦我得到高于14-areh的数字,作业就会开始执行并立即终止。 tracejob非常无益:

tracejob 14753.hpc2

Job: 14753.hpc2

我有时成功地要求更多cpus,所以它不是完全确定的。有没有办法调试这个?

作为一个副节点,任何请求多个节点的作业永远都在队列中并且永远不会启动,我不知道这是否相关。

答案 0 :(得分:0)

您是否尝试执行“qrun”并强行尝试在指定的vnode上启动此作业?

如果没有,你能分享vnode hpc2 [0]的pbsnodes数据吗?

作为一种可能的解决方案,请尝试重启妈妈或将共享设置为妈妈独家(当然,您需要成为特权用户才能这样做)。
