HiPerGator users may finely control what compute nodes are requested by a given SLURM job (e.g. a specific chip families or processor models) by using the --constraint directive to specify the node features they desire:
#SBATCH --constraint=<node_feature>
Using node features as job constraints
Commonly constrained features
A non-exhaustive list of commonly used feature constraints, found to be generally useful:
| Feature
|
Description
|
Available Constraints
|
| Compute partition |
Requests nodes within a specified compute partition |
hpg1 , hpg2
|
| Chip family |
Requests nodes having processors of a specified chip vendor |
amd , intel
|
| Chassis model |
Requests nodes having a specified chassis model |
c6145 , sos6320
|
| Processor model |
Requests nodes having a specified processor model |
o6220 , o3678 , o4184
|
| Network fabric |
Requests nodes having an Infiniband interconnect |
infiniband
|
- Example
Use node features as SLURM job constraints. To ask for 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.
