Upgrade

How to upgrade?

sudo pip install --upgrade aws-parallelcluster

ENHANCEMENTS

• Permit to update the external shared storage of type Efs, FsxLustre, FsxOntap, FsxOpenZfs and FileCache
  without replacing compute and login fleet.

  to TERMINATE. ParallelCluster will terminate only the nodes removed during a resize of the cluster capacity
  performed through a cluster update.

  instead of looping over MaximumNetworkCards range.
• Fail cluster creation when using instance types P3, G3, P2 and G2 because their GPU architecture is not compatible with Open Source Nvidia Drivers (OpenRM) introduced as part of 3.8.0 release.
• Upgrade the default FSx Lustre server version managed by ParallelCluster to 2.15.

Upgrade

How to upgrade?

sudo pip install --upgrade aws-parallelcluster

ENHANCEMENTS

  Possible values are all-or-nothing, greedy-all-or-nothing, best-effort, with all-or-nothing being the default.
• Add HeadNode/SharedStorageType parameter to use EFS storage instead of NFS exports from the head node root volume
  for intra-cluster shared file system resources: ParallelCluster, Intel, Slurm, and /home data. This enhancement reduces the load on the head node networking.

• Remove support of all_or_nothing_batch configuration parameter in the Slurm resume program, in favor of the new Scheduling/ScalingStrategy cluster configuration.
• Changed cluster alarms naming convention to '[cluster-name]-[component-name]-[metric]'.
• Change default EBS volume types in ADC regions from gp2 to gp3, for both the root and additional volumes.
• The optional permissions boundary for the ParallelCluster API is now applied to every IAM role created by the API infrastructure.
