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
/schedand/sharedexports.
Resolved issues
- Azure CycleCloud users using Microsoft Entra Authentication without the
/ssoRedirectURI 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-serverservice occasionally failed on Alma Linux 8 due to a race condition in systemd service startup. - All nodes started the
nfs-serversystem 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
PATHenvironment 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
EncryptionAtHostsetting 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 subscriptionswhen 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).
