We're excited to announce the release of AWS ParallelCluster 2.5.1.

Upgrade

How to upgrade?

sudo pip install --upgrade aws-parallelcluster

Enhancements

  • Add --show-url flag to pcluster dcv connect command in order to generate a one-time URL that can be used to start a DCV session. This unblocks the usage of DCV when the browser cannot be launched automatically.

Changes

  • Upgrade CUDA library to version 10.2.
  • Using a Placement Group is not required anymore but highly recommended when enabling EFA.
  • Increase default root volume size in Centos 6 AMI to 25GB.
  • Increase the retention of CloudWatch logs produced when generating AWS Batch Docker images from 1 to 14 days.
  • Increase the total time allowed to build Docker images from 20 minutes to 30 minutes. This is done to better deal with slow networking in China regions.
  • Upgrade EFA installer to version 1.7.1:
    • Kernel module: efa-1.4.1
    • RDMA core: rdma-core-25.0
    • Libfabric: libfabric-aws-1.8.1amzn1.3
    • Open MPI: openmpi40-aws-4.0.2

Bug Fixes

  • Fix installation of NVIDIA drivers on Ubuntu 18.
  • Fix installation of CUDA toolkit on Centos 6.
  • Fix invalid default value for spot_price.
  • Fix issue that was preventing the cluster from being created in VPCs configured with multiple CIDR blocks.
  • Correctly handle failures when retrieving ASG in pcluster instances command.
  • Fix the default mount dir when a single EBS volume is specified through a dedicated ebs configuration section.
  • Correctly handle failures when there is an invalid parameter in the aws config section.
  • Fix a bug in pcluster delete that was causing the cli to exit with error when the cluster is successfully deleted.
  • Exit with status code 1 if pcluster create fails to create a stack.
  • Better handle the case of multiple or no network interfaces on FSX filesystems.
  • Fix pcluster configure to retain default values from old config file.
  • Fix bug in sqswatcher that was causing the daemon to fail when more than 100 DynamoDB tables are present in the cluster region.
  • Fix installation of Munge on Amazon Linux, Centos 6, Centos 7 and Ubuntu 16.
