Manage a queue

Last Updated: Aug 04, 2021

Elastic High Performance Computing (E-HPC) allows you to classify the compute nodes that run different jobs or perform different tasks by adding them to different queues. This topic describes how to create a queue, add compute nodes to a queue, and delete a queue in the E-HPC console.

Create a queue

  1. Log on to the E-HPC console.

  2. In the upper-left corner of the top navigation bar, select a region.

  3. In the left-side navigation pane, choose Resource Management > Nodes.

  4. In the Cluster drop-down list, select a cluster.

  5. In the Node Type drop-down list, select Compute Node.

  6. In the Node List section, click New Queue.

  7. In the New Queue panel, specify a queue name. Click OK.

Move compute nodes from a queue to another queue

  1. Log on to the E-HPC console.

  2. In the upper-left corner of the top navigation bar, select a region.

  3. In the left-side navigation pane, choose Resource Management > Nodes.

  4. In the Cluster drop-down list, select a cluster.

  5. In the Node Type drop-down list, select Compute Node.

  6. In the Node List section, select the compute nodes that you want to move. Click Move To.

  7. In the Move To panel, select the destination queue. Click OK.

Delete a queue

  1. Log on to the E-HPC console.

  2. In the upper-left corner of the top navigation bar, select a region.

  3. In the left-side navigation pane, choose Resource Management > Nodes.

  4. In the Cluster drop-down list, select a cluster.

  5. In the Node Type drop-down list, select Compute Node.

  6. In the Node List section, select the queue that you want to delete. Click Delete Queue.

  7. In the Delete Queue message, click OK.

    Note

    • The default queue of a cluster cannot be deleted.

    • If a queue belongs to a cluster that uses a scheduler, it cannot be deleted when it contains nodes.
