Request a Queue Reservation

TACC clusters consistently operate at very high node occupancy, meaning compute nodes are not necessarily instantly available for interactive sessions or batch jobs. However, PIs may request a queue reservation for a specific date, time, duration, and number of nodes.

Submit a Request

To make a reservation request, please submit a ticket here. Include the following information in the request:

  • TACC cluster name
  • Start date / time
  • End date / time
  • Number of nodes in the reservation
  • Name of instructional project / allocation
  • List of usernames who should have access

Your instructional allocation will be billed for the entire duration of the reservation. For example, if you reserve 30 nodes for 3 hours, your allocation will be charged (30 x 3) 90 SUs whether or not they are all actively used for the entire reservation. Please submit requests at least two weeks before the desired start date.

Use a Reservation

For an interactive session, use the following flag:

[login]$ idev -r reservation_name

For a batch job, use the following flag:

[login]$ sbatch --reservation=reservation_name myjobscript.slurm
