HiPerGator users may finely control selection of compute hardware for a SLURM job like specific processor families, processor models by using the --constraint directive to specify node features.
- Example
Use one of the following commands to specify between rome and milan microarchitectures
#SBATCH --constraint=rome #SBATCH --constraint=milan
Basic boolean logic can be used to request combinations of features. For example, to request nodes that have Intel processors AND InfiniBand interconnect use
#SBATCH --constraint='intel&infiniband'
To request processors from either AMD Rome OR Milan CPU family use
#SBATCH --constraint='rome|milan'
All Node Features
You can run nodeInfo command from the ufrc environment module to list all available SLURM features. In addition, the table below shows automatically updated nodeInfo output as well as the corresponding CPU models.

Note: the bigmem partitions are maintained for calculations requiring large amounts of memory. To submit jobs to this partition you will need to add the following directive to your job submission script.
#SBATCH --partition=bigmem
Since our regular nodes have 1TB of available memory we do not recommend using bigmem nodes for jobs with memory requests lower than that.
Note: See GPU_Access for more details on GPUs, such as available GPU memory. The following CPU models are in order from the oldest (HPG2) to the newest (HPG3) - haswell, rome, milan.
