How clustering affects priority and worker selection for jobs

A diagram which shows how the same 4 jobs have their priority sorted differently depending on which cluster the job and worker are each in.

Workers in the / cluster (also known as the 'root')

Jobs are sorted by

1. priority
2. then by job id (first come, first served - FCFS)

Workers in cluster /A

1. jobs in cluster /A are considered first, sorted by
   
   1. priority
   2. then by job id - FCFS
2. cluster /B jobs are considered next, sorted by:
   
   1. priority
   2. then by job id - FCFS

Workers in cluster /B

1. jobs in cluster /B are considered first, sorted by
   
   1. priority
   2. then by job id - FCFS
2. cluster /A jobs are considered next, sorted by:
   
   1. priority
   2. then by job id - FCFS
