Configuring Load and Suspend Thresholds

To configure load and suspend thresholds, click the Load/Suspend Thresholds tab. The Load/Suspend Thresholds tab is shown in the following figure.

You can specify the following parameters:

• The Load Thresholds and the Suspend Thresholds tables, which define overload thresholds for load parameters and consumable resource attributes. See Complex Resource Attributes.

  In the case of load thresholds, overload prevents the queue from receiving further jobs. In the case of suspend thresholds, overload suspends jobs in the queue in order to reduce the load.

  The tables display the currently configured thresholds.

  To change an existing threshold, select it, and then double-click the corresponding Value field.

  To add new thresholds, click Load or Value. A selection list appears with all valid attributes that are attached to the queue. The Attribute Selection dialog box is shown in Figure 1–2. To add an attribute to the Load column of the corresponding threshold table, select an attribute, and then click OK.

  To delete an existing threshold, select it, and then type Control-D or click mouse button 3. You are prompted to confirm that you want to delete the selection.

• Suspend interval. The time interval between suspension of other jobs in case the suspend thresholds are still exceeded.

• Jobs suspended per interval. The number of jobs to suspend per time interval in order to reduce the load on the system that is hosting the configured queue.

See the queue_conf(5) man page for detailed information about these parameters.
