Azure CycleCloud 8.1 Release Highlights

CycleCloud 8.1 is the first GA release of the CycleCloud 8.x platform, and contains significant updates from the CycleCloud 7.x versions.

Univa Grid Engine is a Supported Scheduler Type
A free, demo version of Univa Grid Engine is available in CycleCloud 8, with a simple path to full end-to-end enterprise support for Univa clusters running on Azure. Learn more about Univa + Azure here

Slurm Cluster Updates
Slurm clusters deployed in CycleCloud 8 can now be configured to do Slurm job accounting. Additionally, GPU resources on nodes are now recognized automatically, with node partitions autoscaling based on GPU resource requests.
Autoscaling Library
A new, open-source, autoscaling library is now implemented in CycleCloud 8, simplifying autoscaler development for any scheduler in Azure. This new autoscaling library drives the Univa Grid Engine scaling on Azure, and is also used in the open-source Grid Engine clusters.
NAS Options in Default Cluster Templates
Default cluster templates shipped in CycleCloud 8 now include a section for configuring network filesystem mounts. With this, mounting NFS shares no longer requires changes to a cluster template.

Azure Event Grid Integration
CycleCloud 8 generates events when certain node or cluster changes occur, and these events can now be published to Azure Event Grid. With this integration, you can create triggers to events like Spot VM evictions or node allocation failures.

Cloud-Init Support
CycleCloud now supports cloud-init as a way of customizing virtual machines as they boot up. Users can now specify a cloud-init config that will be processed before the CycleCloud configuration occurs. This allows users to baseline a VM by configuring volumes, mounts, networking, or OS before the scheduler stack is set up.

Improved Boot Time
CycleCloud 8 also brings significant improvements to the node preparation stages that happen after a virtual machine is provisioned, decreasing the amount of time needed to fully configure a VM into a member of a HPC cluster.
