Exercise 8b: Priority

DAGMan can change the standard prioritization, if it is specified for a node in the dag file. For example, if there are three CHILD Nodes related to the same PARENT and it is necessary to submit the one of them first and then the other two, set Priority in the dag file.

In this exercise, set priority to Job C in order for it to be submitted before Job B.

Create exercise8b.dag using the following:

JOB A A.sub
JOB B B.sub
JOB C C.sub
JOB D D.sub
PARENT A CHILD B C
PARENT B CHILD D
PARENT C CHILD D
Priority C 10

Execute condor_submit_dag exercise8b.dag to submit the DAG.

The exercise8b.dag.nodes.log file, shows that Node C submitted first and then Node B.
