WebMO Help - Batch Queue Manager (Enterprise)

Batch Queues

WebMO Enterprise allows jobs to be submitted to an external batch queue and then run on compute nodes. Batch queues are commonly found on computer clusters, in which users submit jobs on a head node that are then run on compute nodes.

Preparing for Batch Queues

Batch queue software must be installed on the head node/web server and on compute nodes prior to its use by WebMO, as described in the batch queues documentation. Batch queues can then be enabled and used as described below.

Enabling Batch Queuing

The Batch Queue Manager is enabled from System Manager by selecting an external batch queue for the queuing system and clicking the Submit button. Upon returning the the Admin menu, the Batch Queue Manager link will be visible.

Defining Batch Queues

Click the Batch Queue Manager link to define and configure batch queues.

The name of one or more system batch queues must be specified on the Queues tab. Click the New Queue button, and supply the name a system batch queue.

The system batch queue commands are defined on the settings tab, along with the protocol (rsh, ssh) for accessing compute nodes.

Configuring Batch Queue Engines

Enable and configure computational engines for each defined webmo queue.

Click the Interface Manager link.

In the Queue dropdown menu, select the queue to edit and click the Change button. The queue name will be displayed at the top.

Click the Enable interface icon for each installed computational engine.

Click the Edit interface icon for each installed computational engine to access the {Engine} Manager for the queue, enter the configuration data, and click the Submit button. Note that the program file locations and scratch directory must be defined as all compute nodes would see them.

Repeat for each queue.

When done, click the Return to Admin button.

Logout from being the WebMO administrator, login as a regular WebMO user, and run a test job.
