Hi,

I am new to PBS. How to start the job at a particular time after the first job completes.  
I mean, do we have in PBS similar to “#BSUB -b xxxxxxxxxx” which says…  
“Dispatches the job for execution on or after the specified date and time”

Regards,  
Krish.

qsub -a should do something similar, check out section 2.61.3 of the Ref guide: [https://pbsworks.com/pdfs/PBSRefGuide14.2.pdf](https://pbsworks.com/pdfs/PBSRefGuide14.2.pdf)

If you really want one job to start after another, then consider using the afterok job dependency. It’s there to start one job after another one finishes successfully.
