Summary

HiPerGator users may finely control the compute nodes requested by a given SLURM job (e.g. specific chip 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.

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
Chip family amd , intel Requests nodes having processors of a specified chip vendor
Chassis model c6145 , sos6320 Requests nodes having a specified chassis model
Processor model o6220 , o3678 , o4184 Requests nodes having a specified processor model
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 Intel Sandy Bridge OR Haswell CPU families:

#SBATCH --constraint='sandy-bridge|haswell'

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 and run the following command:

$ nodeInfo
