AWS::PCS::ComputeNodeGroup SlurmConfiguration

Additional options related to the Slurm scheduler.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "GresCustomSettings" : [ {Key: Value, ...}, ... ],
  "ScaleDownIdleTimeInSeconds" : Integer,
  "SlurmCustomSettings" : [ SlurmCustomSetting, ... ]
}

Properties

GresCustomSettings

The additional Slurm gres.conf records for the compute node group. Each item is a map of gres.conf attribute names to values that describes one gres.conf record, such as a GPU topology, MIG, MPS, or custom GRES entry. Amazon PCS adds the NodeName= prefix and merges these records with the GPU record it derives from the instance type.

Required: No

Type: Array of Object

Update requires: No interruption

ScaleDownIdleTimeInSeconds

The time (in seconds) before an idle compute node is scaled down. Overrides the cluster-level ScaleDownIdleTimeInSeconds. If removed from the template, CloudFormation sets the value to -1, reverting to the cluster-level setting. Valid values: 1–10000000. Requires Slurm version 25.11 or later.
