Before you configure an execution host, you must first install the software on the execution host as described in How to Install Execution Hosts in Sun N1 Grid Engine 6.1 Installation Guide.
To configure execution hosts, on the QMON Main Control window click the Host Configuration button, and then click the Execution Host tab. The Execution Host tab looks like the following figure:
Administrative or submit commands are allowed from execution hosts only if the execution hosts are also declared to be administration or submit hosts. See Configuring Administration Hosts With QMON and Configuring Submit Hosts With QMON.
The Load Scaling list displays the currently configured load-scaling factors for the selected execution host. See Load Parameters for information about load parameters.
The Access Attributes list displays access permissions. See Chapter 4, Managing User Access for information about access permissions.
The Consumables/Fixed Attributes list displays resource availability for consumable and fixed resource attributes associated with the host. See Complex Resource Attributes for information about resource attributes.
The Reporting Variables list displays the variables that are written to the reporting file when a load report is received from an execution host. See Defining Reporting Variables for information about reporting variables.
The Usage Scaling list displays the current scaling factors for the individual usage metrics CPU, memory, and I/O for different machines. Resource usage is reported by sge_execd periodically for each currently running job. The scaling factors indicate the relative cost of resource usage on the particular machine for the user or project running a job. These factors could be used, for instance, to compare the cost of a second of CPU time on a 400 MHz processor to that of a 600 MHz CPU. Metrics that are not displayed in the Usage Scaling window have a scaling factor of 1.
To add or modify an execution host, click Add or Modify. The Add/Modify Exec Host dialog box appears.
The Add/Modify Exec Host dialog box enables you to modify all attributes associated with an execution host. The name of an existing execution host is displayed in the Host field.
If you are adding a new execution host, type its name in the Host field.
The Load column of the Load Scaling table lists all available load parameters, and the Scale Factor column lists the corresponding definitions of the scaling. You can edit the Scale Factor column. Valid scaling factors are positive floating-point numbers in fixed-point notation or scientific notation.
The Usage column of the Usage Scaling table lists the current scaling factors for the usage metrics CPU, memory, and I/O. The Scale Factor column lists the corresponding definitions of the scaling. You can edit the Scale Factor column. Valid scaling factors are positive floating-point numbers in fixed-point notation or scientific notation.
To define the resource attributes to associate with the host , click the Consumables/Fixed Attributes tab.
The resource attributes associated with the host are listed in the Consumables/Fixed Attributes table.
Use the Complex Configuration dialog box if you need more information about the current complex configuration, or if you want to modify it. For details about complex resource attributes, see Complex Resource Attributes.
The Consumables/Fixed Attributes table lists all resource attributes for which a value is currently defined. You can enhance the list by clicking either the Name or the Value column name. The Attribute Selection dialog box appears, which includes all resource attributes that are defined in the complex.
To add an attribute to the Consumables/Fixed Attributes table, select the attribute, and then click OK.
To modify an attribute value, double-click a Value field, and then type a value.
To delete an attribute, select the attribute, and then press Control-D or click mouse button 3. Click OK to confirm that you want to delete the attribute.
To define user access permissions to the execution host based on previously configured user access lists, click the User Access tab.
To define project access permissions to the execution host based on previously configured projects, click the Project Access tab.
To define reporting variables, click the Reporting Variables tab.
The Available list displays all the variables that can be written to the reporting file when a load report is received from the execution host.
Select a reporting variable from the Available list, and then click the red right arrow to add the selected variable to the Selected list.
To remove a reporting variable from the Selected list, select the variable, and then click the left red arrow.
To delete an execution host, on the QMON Main Control window click the Host Configuration button, and then click the Execution Host tab.
In the Execution Host dialog box, select the host that you want to delete, and then click Delete.
To shut down an execution host daemon, on the QMON Main Control window click the Host Configuration button, and then click the Execution Host tab.
In the Execution Host dialog box, select a host, and then click Shutdown.
