Advanced Dependencies

The next step is to build a more robust dependency system

Building on what we have learnt in the previous tutorials this tutorial will:

Feel free to download an run the below script as it setup a job that will :

Create a Parent "Sleep job" with a range of 60
Create a Blocked Child "Sleep job" that links to the Parent job and waits for a complete status before starting

This script differs from the rest quiet a lot

task = []

To create a list of jobs that are submitted

task.append(job)

Combines the list of jobs for final submission by

listOfSubmittedJobs = qb.submit(task)

With this method the jobs are not submitted per "job = {}" instead combined and submitted once all tasks have completed

job['label']= 'ParentLabel'

This creates a internal label for the job which is assessed at submission time

job['dependency'] = 'link-complete-job-ParentLabel'

The Child job then uses the internal label to link to the Parent job.

Here are some examples of how you can link the jobs :

job['dependency'] = 'link-complete-job-ParentLabel'

This will run once the Parent job is complete

job['dependency'] = 'link-failed-job-ParentLabel'

This will run once the Parent job is failed

job['dependency'] = 'link-killed-job-ParentLabel'

This will run if the Parent job has been killed

job['dependency'] = 'link-done-job-ParentLabel'

This will run once the Parent job returns a status of done. Done means if the job completes,fails or has been killed

You can also link jobs by different types

job['dependency'] = 'link-done-work-ParentLabel'

This will run depending on the status of the jobs work

job['dependency'] = 'link-done-subjob-ParentLabel'

This will run depending on the status of the jobs subjobs
