SLURM Reservations

Reservations for slurm nodes/resources can be requested by submitting a ticket by email to cshelpdesk@virginia.edu. We can give out reservations for a specific amount of computing resources (Cores, Mem, GPU count, etc.) or by reserving an entire compute node or node group (i.e. slurm1 or slurm[1-5]).

In your request for a reservation, please be specific about:

  1. What resources are needed
  2. How long they will be needed
  3. Who has rights to use reservation (list of user IDs)

If you have been granted a reservation you will receive a reservation tag, a short string that is required to submit jobs. This string must be included in any srun or sbatch submissions via the flag --reservation=....

If our tag is “abcde_4” then you would submit jobs using the flag --reservation=abcde_4

This can be done at the command line:

sbatch --reservation=abcde_4 slurm.sh
...
srun --reservation=abcde_4 slurm.sh

Or you can include the flag in the header of your sbatch file:

reservation.sh

#!/bin/bash
 
#SBATCH --job-name="Reservation Example" 
#
#SBATCH --error="stderr.txt"
#SBATCH --output="stdout.txt"
#
#SBATCH --reservation=abcde_4
 
...
sbatch reservation.sh
