AWS Parallel Computing Service expands Slurm customization capabilities

AWS Parallel Computing Service (AWS PCS) Updates

AWS PCS now offers expanded Slurm configuration capabilities, enabling you to set over 60 additional parameters for granular control over your HPC cluster operations. This enhancement provides more flexibility in managing job scheduling, resource allocation, access control, and job lifecycle.

The new Slurm custom settings give you fine-grained control over various resource management scenarios, including fair-share scheduling and quality of service levels. You can now implement queue-specific priority policies, configure preemption settings, and set custom time and resource limits. Additionally, you can control access permissions at the account level and configure per-job execution behaviors.

What to do

• Explore the new Slurm custom settings in the AWS PCS User Guide.
• Update your HPC cluster configurations to take advantage of the new capabilities.
• Test the new settings in a staging environment before deploying to production.

Expanded Slurm custom settings are available in all AWS Regions where AWS PCS is available. To learn more, see the AWS PCS User Guide.
