DONE: Reservations: The ability to reserve nodes far in the future for things like CASA classes and SIW would be very helpful. It would need to prevent HTCondor from starting jobs on these nodes as reservation time approaches.

- scontrol create reservation starttime=now duration=5 nodes=testpost001 user=root
- scontrol create reservation starttime=2022-05-3T08:00:00 duration=21-0:0:0 nodes=nmpost[020-030] user=root reservationname=siw2022
- scontrol show res The output of this kinda sucks. Hopefully there is a better way to see all the reservations.
- HTcondor
- There isn't a reservation feature in HTCondor. Since CHTC makes use of preemption, their nodes can be removed at almost any time without adversely affecting running jobs. Sadly NRAO cannot really use preemption.

- pbs_rsub makes reservations but they are very different than torque. The following will make a reservation for the host nmpost001 as the user the runs the command. Root cannot make reservations.
- pbs_rsub -N siw2022 -R 202205030800 -E 202205240800 -l select=host=rastan nmpost001 -l place=exclhost
- Then when this reservation time starts you will need to do something like kill pbs_mom and edit access.conf. Not as sexy as Torque/Moab.
