Drill Down to Nodes by Cluster or Queue

Drill-down to get node information about the nodes in a cluster, nodes attached to queue, or a subset of nodes in either of these categories filtered by a condition.

A colored bar graphically depicts the condition of cluster's nodes. The below table describes the conditions represented by each color and the associated node states.
Color Condition State
Red requires attention down, stale, state-unknown, unresolvable
Green in use job-busy, job-excl, resv-exclusive
Purple unavailable offline, provisioning, wait-provisioning
Yellow available free
Orange idle idle

Drill Down to Node Details for an HPC Cluster

Drill-down to a get detailed information about the HPC cluster's nodes such as the state of the node, and the availability of CPUs and memory.

Drill-down for detailed node information for all cluster nodes or nodes in a specific condition.

  1. Click the Monitor tab.
  2. Click the Nodes tab from the PBS Professional menu located on the left-hand side of the web page.
  3. Choose one of the following options:
    • To view all HPC nodes, click the number under the Nodes column.
    • To view nodes that are in a specific condition, click the appropriate colored area of the Status bar.

    A list matching the selected filtering requirements is presented with each row representing a node.

Drill Down to Nodes Attached to a Queue

Drill-down to view node details of nodes that have been attached to a queue.

Drill-down to see all nodes that have been attached to a queue or nodes attached to a queue that are in a specific condition.

  1. Click the Monitor tab.
  2. Click the Nodes tab from the PBS Professional menu located on the left-hand side of the web page.
  3. Optional: If the cluster's queues are not visible, click the name of the cluster to expand it.
    The queues attached to the cluster nodes are displayed. Each queue is represented by a row containing the queue name, a colored bar graphically depicting the status of the nodes attached to the queue, and the number of nodes attached to the queue
  4. Choose one of the following options:
    • To view all the nodes attached to that queue, click the number under the Nodes column.
    • To view nodes attached to the queue nodes that are in a specific condition, click the appropriate colored area of the Status bar.

Understand the Node Detail View

A detailed view of an HPC cluster's nodes including the state of the node and resource availability.

The Node Detail view displays the HPC cluster's nodes. By default, each node is represented by a row containing the following information:
  • the name of the node
  • the state of the node
  • number of CPUs being used / total number of CPUs present on the node
  • amount of memory being used / total memory present on the node
  • a comma separated list of the jobs running on the node in the format jobid/cpu_no where cpu_no identifies the CPU that is being used by the job. CPUs are numbered from 0 to n.
  • comments added by the WLM administrator or the WLM itself about the node

Presently, node management cannot be done at the vnode level, therefore you cannot select a vnode to take it offline or place it online.
