is there a way to change the walltime for currently running PBS job
I underestimated the amount of time a job would take. Would it be possible to change the time limit for a job while it is running?
Solution 1:
qalter jobid -l walltime=X
You can read the qalter
docs here.
Solution 2:
Yes You can use:
qalter [-l resource_list] Job_ID
For Example:
qalter -l walltime=01:00:00 121214
Also, try to do it while the job is still queued because once it starts, this may not work & you will get a response "Unauthorized Request". Then you would need root permission to overwrite an unauthorized request.
