Available Node Features

Introduction

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.

Using node features as job constraints

Usage Example

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.

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
