AWS Parallel Computing Service (PCS) now supports node reboot via Slurm

AWS Parallel Computing Service (PCS) Update

AWS PCS now allows you to reboot compute nodes using Slurm commands without triggering instance replacement. This feature helps maintain cluster health efficiently at lower costs.

New Feature

You can now reboot nodes for operational reasons such as troubleshooting, resource cleanup, and recovery from degraded states before requiring full node replacement.

What to do

• Use the 'scontrol reboot' command with options to schedule immediate or deferred reboots.
• Refer to Rebooting compute nodes with Slurm in AWS PCS for more details.
