Hello,
I want to create file in $PBS_O_WORKDIR few minutes before specified walltime exceeds.
anyone have idea about above query please let me know.
Thank you in advance.
-
server periodic hook or cronjob
- threshold time to create file is 95% of walltime is used
- find out remaining walltime ( used_walltime , requested_walltime , available_walltime)
- write a file when the threshold is about to reached.
-
implement some kind of timer within the script, when it is about to hit the 98% threshold of your requested walltime , then write a file.
@adarsh Thank you for possible solutions,
- If i go with hooks, how we can implent this hooks for specific jobs instead of all jobs on cluster.
Specific jobs needs to be tagged for this , requesting
- for example specific user or list of users
– for example specific software or list of softwares
– for example specific queue or queue(s)
And can I fetch job_ib in submission script after qsub command, As right now I’m trying to echo $PBS_JOBID but it is showing my remote session jobid through which I’m submitting my job.
Hi
A hook is the best way but for a quick and dirty way you could implement it using bash within the submission script:
- At the start of the PBS sub script get the system time, add 95% of walltime to get the time at which to create the directory. This can be done using bash arithmetic.
- Set a user cron job to create the directory at that time.
- The rest of the submission script is your normal commands.
A hack but it would probably work with little effort.

@speleolinux @adarsh Actually i created script and merged this script with job submission script but now i stuck on 1 things,
- How we can get start time of queued job right after job submission, as using qstat -f we can’t get start time until job gets start execution.
