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
#SBATCH --constraint=westmere

or

#SBATCH --constraint=haswell

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 Intel Haswell OR skylake CPU family use

#SBATCH --constraint='haswell|skylake'

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 following features correspond to the following cpu models in order from the oldest to the newest - interlagos, magny, sandy-bridge, dhabi, haswell, broadwell, skylake. The 'dhabi' and 'haswell' models are from HPG1 and HPG2 deployments.
