Job Dependencies
One can indicate a dependency between two or more jobs by using the -W x=depend:dependency-type:jobid flag for the msub commando. For example to tell moab that job2.sh can only run after job1.sh successfully finishes, one can use:
$ msub job1.sh
12345
$ msub -W x=depend:afterok:12345 job2.sh
12346
This will queue job1.sh with a jobid of 12345, queue job2.sh with jobid 12346 and indicate moab that job2.sh has to wait until job1.sh has finished.
