CRC How To Request Exclusive Access To A Node Via SLURM

Introduction

It is possible to request exclusive access to a node so that you will not share it with anyone else regardless of how many processors you need on that node. This might be important for memory or disk intensive jobs where interference from other jobs would impact performance.

Requesting Exclusive Access

Use the following lines in your SLURM batch script:

#SBATCH --nodes=1
#SBATCH --exclusive

This combination of options will give the user one node and will have exclusive access to the entire node.
