Summary

HiPerGator users may finely control the compute nodes requested by a given SLURM job (e.g. specific processor families, processor models) by using the --constraint directive to specify the node features they desire. Note that the partition must be selected if it's not the default partition. If a partition is not specified by default the jobs will be sent to both 'hpg1-compute,hpg2-compute' partitions.

Example
#SBATCH --partition=hpg1-compute
#SBATCH --constraint=westmere

but 

#SBATCH --constraint=haswell

for the default hpg2-compute partition.

Using node features as job constraints

Commonly constrained features

Use node features as SLURM job constraints.

A non-exhaustive list of commonly used feature constraints, found to be generally useful:

Feature Constraints Description
Compute partition hpg1 , hpg2 Requests nodes within a specified compute partition
Processor family amd , intel Requests nodes having processors of a specified vendor
Network fabric infiniband Requests nodes having an Infiniband interconnect
Examples

To request an Intel processor, use the following: 

#SBATCH --contstraint=intel

To request nodes that have Intel processors AND InfiniBand interconnect: 

#SBATCH --constraint='intel&infiniband'

To request nodes that have processors from the Haswell 'OR Skylake Intel CPU families: 

#SBATCH --constraint='haswell|skylake'

All Node Features

This data has been automatically extracted from node information in SLURM and system processor information and represents all available Processor models and other node features on HiPerGator.

Node features by partition

HiPerGator node features are documented comprehensively below, sectioned by partition. Use the table columns headings within each section to sort by the criteria of your choice.

This documentation will be updated periodically. To request current node feature information directly from the cluster, load the ufrc module module load ufrc and run the following command:
