Azure CycleCloud version 8.8.2

This release introduces highly requested new features, addresses several key issues, and improves overall performance.

New Features

  • The basic Network File System (NFS) cluster type now includes a parameter option to enable the /sched and /shared exports.

Resolved issues

  • Azure CycleCloud users using Microsoft Entra Authentication without the /sso RedirectURI configured in the App Registration would encounter an authentication failure in the browser UI after the page was idle for over 12 hours requiring sign-out and then sign-back-in to resolve.
  • Slurm clusters running on Alma Linux 9 failed to set instance host names to the node name.
  • The nfs-server service occasionally failed on Alma Linux 8 due to a race condition in systemd service startup.
  • All nodes started the nfs-server system service even if no filesystem was exported.
  • Copy Row/Cell on the Activity Log table failed to copy the content.
  • The azslurm CLI installation in Slurm clusters destructively modified the PATH environment variable for all cluster users when enabling tab-completion for the CLI.
  • The Azure High-Performance Computing (HPC) images converged slowly due to the default udev rules installed by Jetpack.
  • Modifying the EncryptionAtHost setting on a running cluster resulted in a "mismatched attributes" error even though it doesn't modify the Virtual Machine Scale Set model.
  • Node configuration failed when using the CycleCloud orchestration Credentials rather than separate Managed Identity for the cluster's Storage Locker.
  • CycleCloud Slurm clusters failed installation on the most recent Alma 8 HPC image versions due to missing the python-yaml package.
  • Sun GridEngine (SGE) clusters failed to converge due to python version issues on the latest Ubuntu HPC images.
  • Azure doesn't report GPU count for GB300 machine types. This caused CycleCloud to report zero GPUs (instead of four GPUs) to Slurm and other schedulers.
  • In some Slurm cluster configurations, enroot installation could fail due to a missing newline at the end of the enroot.conf file.
  • The CycleCloud UI sometimes displayed an error saying This installation of Azure CycleCloud has no subscriptions when a user's login expired (rather than redirecting and refreshing the login).

Known Issues

All tenants using Entra for CycleCloud Authentication should add a Redirect URI for the /sso endpoint (see Step 2 in Configuring Redirect URIs for Entra App Registration).
