How can I scatter (i.e. round-robin) multiple jobs over the vnodes?
With our current configuration, when I submit 5 jobs that uses a little amount of shared resource, they are assigned to a single vnode together:
- vnode1: job1, job2, job3, job4, job5
- vnode2: (vacant)
- vnode3: (vacant)
I want them to be assigned to different vnodes so as to avoid speeddown caused by resource contention:
- vnode1: job1, job4
- vnode2: job2, job5
- vnode3: job3
I know I can scatter multiple chunks in a single job, but I failed to find the way to scatter multiple independent jobs.
Any comments or suggestions would greatly be appreciated.
