Job dependencies

Sometimes, whether a job should start depends on the result of another job. To submit a job that depends on another job:

  1. use the -w option to bsub (it is lowercase w)
  2. Select dependency expression
  3. select dependency condition

Example 1:

bsub -q medium -R "rusage [mem=1000] span[hosts=1]" -J"dependent-1" -o ~/job.output myjob  
Job <9773> is submitted to queue <medium>

bsub -q medium -R “rusage [mem=1000] span[hosts=1” –J”dependent-2”-o ~/job.output -w 'done("dependent-1")' myjob
Job <9774> is submitted to queue <medium>

bsub -q medium -R “rusage [mem=1000] span[hosts=1]” -o ~/job.output -w 'ended(9773)' myjob
Job <9775> is submitted to queue <medium>

bsub -J "dependency_1" -q medium -R ‘rusage [mem=1000] span[hosts=1’ -o ~/lsf.output myjob
Job <9776> is submitted to queue <medium>

bsub -J "dependency_2" -q medium -R ‘rusage [mem=1000] span[hosts=1’ -o ~/output -w 'exit("dependent_1")&&post_done("dependency_2")' myjob
Job <9777> is submitted to queue <medium>

bsub -J "dependent_3" -q medium -R ‘rusage [mem=1000] span[hosts=1’ -o ~/lsf.output myjob
Job <9778> is submitted to queue <medium>

bsub -J "dependency_4" -q medium -R ‘rusage [mem=1000] span[hosts=1]’ -o ~/lsf.output -w 'exit("dependent_3")||post_done("dependent_3")' myjob
