Job dependencies - Slurm¶
A job can be given the constraint that it only starts after another job has finished.
Example
Assume we have two Jobs, A and B. We want Job B to start after Job A has successfully completed.
First we start Job A (with submit file jobA.sh) by submitting it via sbatch:
Making note of the assigned job-id for Job A (JOBID-JobA), we then submit Job B (with submit file jobB.sh) with the added condition that it only starts after Job A has successfully completed:
If we want Job B to start after several other Jobs have completed, we can specify additional jobs, using a ‘:’ as a delimiter:
We can also tell slurm to run Job B, even if Job A fails, like so:
For more information, consult the man page for sbatch.
