| An opt-in node status notification service is available for Caviness users. This service sends an email notification when any nodes in your workgroup transition between two of the following states: | There is no need for an opt-in node status notification service on Caviness because there are no specific nodes assigned to a research workgroup partition for their jobs. All nodes of a particular node type will be available to a workgroup partition, if the research group invested (purchased) that particular node type. For example, say a research group purchased 1 standard node, 1 large memory node with 512 GB and 1 GPU node, then the workgroup partition for this research group would consist of all standard nodes, all nodes with 512 GB and all GPU nodes as the available resources to allocated for their jobs. |
