October 2019

• Cluster Shared State

  The cluster attribute Shared State enables Cloud Center to authorize users to submit jobs to or interact with a cluster from MATLAB. The Shared State may be Personal Cluster (accessible only by you) or Shareable Cluster (accessible to people you have explicitly given access to via a white list). The default Shared State attribute of a cluster is Personal Cluster. This authorization control is unrelated to accessing the cluster via SSH.

  For Shareable Clusters, the person creating the cluster must expressly add authorized users to the Shared With field.

  Note

  Cloud Center clusters created for MATLAB releases prior to R2019b did not have clusters with the Shared State attribute. Those clusters are all implicitly shareable clusters, as any user who imports a cluster profile is authorized to submit jobs to or interact with the cluster from MATLAB. The inbound firewall rules for these clusters are managed only by Global Cluster Access rules.

  For more information, see Sharing Options for Clusters.

• Auto-Manage Cluster Access

  The cluster attribute Auto-Manage Cluster Access allows Cloud Center to manage a cluster’s inbound firewall rules on a cluster-by-cluster basis. Auto-Manage Cluster Access is enabled by default for Personal Clusters.

  Note

  Clusters created prior to R2019b are Shareable Clusters, whose inbound firewall rules are managed only by Global Cluster Access rules.

  For more information, see Manage Cluster Access Automatically.
