Upgrade

How to upgrade?

sudo pip install --upgrade aws-parallelcluster

ENHANCEMENTS

  • Add possibility to specify multiple EC2 instance types for the same compute resource.
  • Add support for adding and removing shared storages at cluster update by updating SharedStorage configuration.
  • Add new configuration parameter DeletionPolicy for EFS and FSx for Lustre shared storage to support storage retention.
  • Add new configuration section Scheduling/SlurmSettings/Database to enable accounting functionality in Slurm.
  • Add support for On-Demand Capacity Reservations and Capacity Reservations Resource Groups.
  • Add new configuration parameter in Imds/ImdsSettings to specify the IMDS version to support in a cluster or build image infrastructure.
  • Add support for Networking/PlacementGroup in the SlurmQueues/ComputeResources section.
  • Add support for instances with multiple network interfaces that allows only one ENI per device.
  • Improve validation of networking for external EFS file systems by checking the CIDR block in the attached security group.
  • Add validator to check if configured instance types support placement groups.
  • Configure NFS threads to be min(256, max(8, num_cores * 4)) to ensure better stability and performance.
  • Move NFS installation at build time to reduce configuration time.
  • Enable server-side encryption for the EcrImageBuilder SNS topic created when deploying ParallelCluster API and used to notify on docker image build events.

CHANGES

  • Change behaviour of SlurmQueues/Networking/PlacementGroup/Enabled: now it creates a different managed placement
    group for each compute resource instead of a single managed placement group for all compute resources.
  • Add support for PlacementGroup/Name as the preferred naming method.
  • Move head node tags from Launch Template to instance definition to avoid head node replacement on tags updates.
  • Disable Multithreading through script executed by cloud-init and not through CpuOptions set into Launch Template.
  • Upgrade Python to version 3.9 and NodeJS to version 16 in API infrastructure, API Docker container and cluster Lambda resources.
  • Remove support for Python 3.6 in aws-parallelcluster-batch-cli.
  • Upgrade Slurm to version 22.05.5.
  • Upgrade NVIDIA driver to version 470.141.03.
  • Upgrade NVIDIA Fabric Manager to version 470.141.03.
  • Upgrade NVIDIA CUDA Toolkit to version 11.7.1.
  • Upgrade Python used in ParallelCluster virtualenvs from 3.7.13 to 3.9.15.
  • Upgrade Slurm to version 22.05.5.
  • Upgrade EFA installer to version 1.18.0.
  • Upgrade NICE DCV to version 2022.1-13300.
  • Allow for suppressing the SingleSubnetValidator for Queues.

BUG FIXES

  • Fix validation of filters parameter in ListClusterLogStreams command to fail when incorrect filters are passed.
  • Fix validation of parameter SharedStorage/EfsSettings: now validation fails when FileSystemId is specified
    along with other SharedStorage/EfsSettings parameters, whereas it was previously ignoring them.
  • Fix cluster update when changing the order of SharedStorage together with other changes in the configuration.
  • Fix UpdateParallelClusterLambdaRole in the ParallelCluster API to upload logs to CloudWatch.
  • Fix Cinc not using the local CA certificates bundle when installing packages before any cookbooks are executed.
  • Fix a hang in upgrading ubuntu via pcluster build-image when Build:UpdateOsPackages:Enabled:true is set.
  • Fix parsing of YAML cluster configuration by failing on duplicate keys.
