Reserving Resources

Some scheduling examples

1 Job5 requests –n 6 –R “span[ptile=2]”, which will require three hosts with 2

CPUs on each host. As in the greedy slot reservation example, four jobs are

running in the cluster:

Job1, Job2, Job3 and Job4. Two CPUs are available now,

1 on host

A, and 1 on host D:

Job2 finishes, freeing 2 more CPUs for future allocation, 1 on host A, and 1 on

host

Job4 finishes, freeing 4 more CPUs for future allocation, 2 on host A, and 2 on

host

Job1 finishes, freeing 2 more CPUs for future allocation, 1 on host C, and 1

host
