change the walltime for currently running PBS job (qalter pbs)

qalter jobid -l walltime=X

e.g.
qalter 377470.manager -l walltime=2222:00:00
qalter: Unauthorized Request  377470.manager

Notes:

To alter requested resources for a currently queued (but not running) job use the qalter command.  You can change the wallclock limit, the account to be charged, email options, the stdout/stderr paths, and the total number of cores needed or the number of cores per node (mppnppn), among other things.  See the "qsub" man page for details. The two important restrictions are that you cannot change any attributes once your job begins running and you cannot change mppwidth so that the job moves across the execution queue boundaries.  Usage examples:

1.hopper% qalter -lwalltime=new_walltime jobid

2.hopper% qalter -lmppwidth=new_mppwidth jobid

 

改变cpu数量：

qalter -l nodes=1:ppn=10  jobid #(小写的L)

修改pbs队列：

qalter <jobid> -W queue=<new queue name>

$ qstat | grep  9999 | grep  AAAA  | sed 's/er.*/er/g' | awk '{print "qalter "$0" -W queue=middleq"}'

修改依赖的job：

qalter -W depend=afterok:6250.centos64 5951.centos64

qalter -W depend=afterok:new_job_id old_job_id

old_job_id 执行完成之后才能执行new_job_id

启动torque：

启动所有服务（需要root权限）
pbs_server
pbs_sched
pbs_mom

批量取消pbs：

qstat | grep zh | grep Q | sed 's/er.*/er/g' | awk '{print "qdel "$0}'
qstat | grep zh | grep H | sed 's/er.*/er/g' | awk '{print "qdel "$0}'

qstat | grep zh | grep R | sed 's/er.*/er/g' | awk '{print "qdel "$0}'
