You have a cluster running with the FIFO scheduler enabled. You submit a large job A to the
cluster which you expect to run for one hour. Then, you submit job B to the cluster, which you
expect to run a couple of minutes only. Let’s assume both jobs are running at the same priority.
How does the FIFO scheduler execute the jobs? (Choose 3)
The order of execution of tasks within a job may vary.
When a job is submitted, all tasks belonging to that job are scheduled.
Given jobs A and B submitted in that order, all tasks from job A will be scheduled before all
tasks from job B.
Since job B needs only a few tasks, if might finish before job A completes.
