Choosing an AWS PCS cluster size

AWS PCS provides highly available and secure clusters, while automating key tasks such as patching, node provisioning, and updates.

When you create a cluster, you select a size for it based on two factors:

  • The number of compute nodes it will manage

  • The number of active and queued jobs that you expect to run on the cluster

Slurm cluster size Number of instances managed Number of active and queued jobs
Small Up to 32 Up to 256
Medium Up to 512 Up to 8192
Large Up to 2048 Up to 16384
Examples
  • If your cluster will have up to 24 managed instances and run up to 100 jobs, choose Small.
