We're excited to announce the release of AWS ParallelCluster Cookbook 2.8.0.

This is associated with AWS ParallelCluster v2.8.0

ENHANCEMENTS

  • Enable support for ARM instances on Ubuntu 18.04 and Amazon Linux 2.
  • Install PMIx v3.1.5 and provide slurm support for it on all supported operating systems except for
    CentOS 6.
  • Install glibc-static, which is required to support certain options for the Intel MPI compiler.

CHANGES

  • Disable libvirtd service on Centos 7. Virtual bridge interfaces are incorrectly detected by Open MPI and
    cause MPI applications to hang, see https://www.open-mpi.org/faq/?category=tcp#tcp-selection for details
  • Use CINC instead of Chef for provisioning instances. See https://cinc.sh/about/ for details.
  • Retry when mounting an NFS mount fails.
  • Install the pyenv virtual environments used by ParallelCluster cookbook and node daemon code under
    /opt/parallelcluster instead of under /usr/local.
  • Avoid downloading the source for env2 at installation time.
  • Drop dependency on the gems ridley and ffi-libarchive.
  • Vendor cookbooks as part of instance provisioning, rather than doing so before copying the cookbook into an
    instance. Users no longer need to have berks installed locally.
  • Drop the dependencies on the poise-python, tar and hostname third-party cookbooks.
  • Use the new official CentOS 7 AMI as the base images for ParallelCluster AMI.
  • Upgrade NVIDIA driver to Tesla version 440.95.01 on CentOS 6 and version 450.51.05 on all other distros.
  • Upgrade CUDA library to version 11.0 on all distros besides CentOS 6.
  • Install third-party cookbook dependencies via local source, rather than using the Chef supermarket.
  • Use https wherever possible in download URLs.
  • Upgrade EFA installer to version 1.9.4:
    • Kernel module: efa-1.6.0 (from efa-1.5.1)
    • RDMA core: rdma-core-28.amzn0 (from rdma-core-25.0)
    • Libfabric: libfabric-1.10.1amazon1.1 (updated from libfabric-aws-1.9.0amzn1.1)
    • Open MPI: openmpi40-aws-4.0.3 (no change)

BUG FIXES

  • Fix issue that was preventing concurrent use of custom node and pcluster CLI packages.
  • Use the correct domain name when contacting AWS services from the China partition.
  • Avoid pinning to a specific release of the Intel HPC platform.
