Queues: We want to keep the queue functionality of Torque/Moab where, for example, hera jobs go to hera nodes, vlass jobs go to vlass nodes. We would also like to be able to have vlasstest jobs go to the vlass nodes with a higher priority without preempting running jobs.
Slurm
- Queues are called partitions. At some level they are called partitions in Torque as well.
- Job preemtion is disabled by default
- Allows for simple priority settings in partitions with the default PriorityType=priority/basic plugin.
- E.g. PartitionName=vlass Nodes=testpost[002-004] MaxTime=144000 State=UP Priority=1000
- HTCondor
- HTCondor doesn't have queues or partitions like Torque/Moab or Slurm but there are still ways to do what we need.
- Using separate pools for things like HERA and VLASS is an option, but may be overkill as it would require separate Central Managers.
- Constraints is an optionConstraints and/or seperate pools are good options.
- I don't know how to simulate the vlass/vlasstest queues. Perhaps by the time we move to HTCondor we won't need vlasstest anymore.
- HTCondor does support accounting groups that may work like queues.
