Upgrade

How to upgrade?

sudo pip install --upgrade aws-parallelcluster

ENHANCEMENTS

  • Add support for RHEL8.7.
  • Add a CloudFormation custom resource for creating and managing clusters from CloudFormation.
  • Add support for customizing the cluster Slurm configuration via the ParallelCluster configuration YAML file.
  • Build Slurm with support for LUA.
  • Increase the limit on the maximum number of queues per cluster from 10 to 50. Compute resources can be distributed flexibly across the various queues as long as the cluster contains a maximum of 50 compute resources.
  • Allow to specify a sequence of multiple custom actions scripts per event for OnNodeStart, OnNodeConfigured and OnNodeUpdated parameters.
  • Add new configuration section HealthChecks/Gpu for enabling the GPU Health Check in the compute node before job execution.
  • Add support for Tags in the SlurmQueues and SlurmQueues/ComputeResources section.
  • Add support for DetailedMonitoring in the Monitoring section.
  • Add mem_used_percent and disk_used_percent metrics for head node memory and root volume disk utilization tracking on the ParallelCluster CloudWatch dashboard, and set up alarms for monitoring these metrics.
  • Add log rotation support for ParallelCluster managed logs.
  • Track common errors of compute nodes and longest dynamic node idle time on Cloudwatch Dashboard.
  • Enforce the DCV Authenticator Server to use at least TLS-1.2 protocol when creating the SSL Socket.
  • Install NVIDIA Data Center GPU Manager (DCGM) package on all supported OSes except for aarch64 centos7 and alinux2.
  • Load kernel module nvidia-uvm by default to provide Unified Virtual Memory (UVM) functionality to the CUDA driver.
  • Install NVIDIA Persistence Daemon as a system service.

CHANGES

  • Note 3.6 will be the last release to include support for Ubuntu 18. Subsequent releases will only support Ubuntu from version 20.
  • Upgrade Slurm to version 23.02.2.
  • Upgrade munge to version 0.5.15.
  • Set Slurm default TreeWidth to 30.
  • Set Slurm prolog and epilog configurations to target a directory, /opt/slurm/etc/scripts/prolog.d/ and /opt/slurm/etc/scripts/epilog.d/ respectively.
  • Set Slurm BatchStartTimeout to 3 minutes so to allow max 3 minutes Prolog execution during compute node registration.
  • Increase the default RetentionInDays of CloudWatch logs from 14 to 180 days.
  • Upgrade EFA installer to 1.22.1
    • Dkms : 2.8.3-2
    • Efa-driver: efa-2.1.1g
    • Efa-config: efa-config-1.13-1

    • Libfabric-aws: libfabric-aws-1.17.1-1
    • Rdma-core: rdma-core-43.0-1
    • Open MPI: openmpi40-aws-4.1.5-1
  • Upgrade Lustre client version to 2.12 on Amazon Linux 2 (same version available on Ubuntu 20.04, 18.04 and CentOS >= 7.7).
  • Upgrade Lustre client version to 2.10.8 on CentOS 7.6.
  • Upgrade NVIDIA driver to version 470.182.03.
  • Upgrade NVIDIA Fabric Manager to version 470.182.03.
  • Upgrade NVIDIA CUDA Toolkit to version 11.8.0.
  • Upgrade NVIDIA CUDA sample to version 11.8.0.
  • Upgrade Intel MPI Library to 2021.9.0.43482.
  • Upgrade NICE DCV to version 2023.0-15022.
    • server: 2023.0.15022-1
    • xdcv: 2023.0.547-1
    • gl: 2023.0.1027-1
    • web_viewer: 2023.0.15022-1
  • Upgrade aws-cfn-bootstrap to version 2.0-24.
  • Upgrade image used by CodeBuild environment when building container images for AWS Batch clusters, from
    aws/codebuild/amazonlinux2-x86_64-standard:3.0 to aws/codebuild/amazonlinux2-x86_64-standard:4.0 and from
    aws/codebuild/amazonlinux2-aarch64-standard:1.0 to aws/codebuild/amazonlinux2-aarch64-standard:2.0.
  • OpenSSL version 1.1.1 or later is required for ParallelCluster CLI due to a change in urllib3 2.0. Using an older OpenSSL will trigger an ImportError when executing a pcluster command.

BUG FIXES

  • Fix EFS, FSx network security groups validators to avoid reporting false errors.
  • Fix missing tagging of resources created by ImageBuilder during the build-image operation.
  • Fix Update policy for MaxCount to always perform numerical comparisons on MaxCount property.
  • Fix an issue that was causing misalignment of compute nodes IP on instances with multiple network interfaces.
  • Fix replacement of StoragePass in slurm_parallelcluster_slurmdbd.conf when a queue parameter update is performed and the Slurm accounting configurations are not updated.
  • Fix issue causing cfn-hup daemon to fail when it gets restarted.
  • Fix issue causing dangling security groups to be created when creating a cluster with an existing EFS.
  • Fix issue causing NVIDIA GPU compute nodes not to resume correctly after executing an scontrol reboot command.
