AWS Parallel Computing Service (PCS) Updates

AWS PCS now supports rotation of cluster secret keys using AWS Secrets Manager, enhancing security by reducing the risk of credential compromise. This feature allows you to update secure credentials for authentication between Slurm controller and compute nodes without creating a new cluster. It is available in all AWS Regions where PCS is offered.

What to do

• Prepare your cluster for the rotation process.
• Rotate cluster secrets using AWS Secrets Manager console or API.
• Follow the PCS User Guide for detailed instructions.
