Autoscaling Clusters
For 2024 R2 and newer releases of Ansys applications
A cluster consists of multiple machines that are networked together. Each machine is called a node. A cluster consists of a head node that handles the job scheduling, and worker nodes that do the work. The nodes work in parallel with each other, boosting processing speed to deliver high performance computing.
An autoscaling cluster is a cluster that automatically scales the number of nodes up or down to meet the demand of the workload. When jobs are submitted to the cluster, nodes are spun up, and as jobs finish, the nodes are shut down.
A cluster can have multiple job submission queues, and each queue can have a different application associated with it.
If a project space to which you have access contains an autoscaling cluster, you can submit batch jobs to the cluster provided that there is a queue with the application that you want to run.
