Hello,
PBS environment (both openpbs and pbspro) has capability to manage
dependencies among jobs. In your case, you should start next jobs with
following option:
qsub ... -W depend=afterany:previous_job_id ...
where previous_job_id is job id returned by qsub from previous job
submission.
Please keep in mind, that it could happen that subsequent jobs will run
on different nodes (it depends on your computer system). Therefore job
script should save final results (at least restart file) to some shared
volume to guarantee their accessibility for next job.
With regards,
Petr
