Hosts and Host Functionality

Clicking the Host Configuration button in the QMON Main Control window displays an overview of the functionality that is associated with the hosts in your cluster. However, without manager privileges, you cannot apply any changes to the configuration.

The host configuration dialog boxes are described in Chapter 1, Configuring Hosts and Clusters, in Sun N1 Grid Engine 6.1 Administration Guide. The following sections describe the commands used to retrieve host information from the command line.

Finding the Name of the Master Host

The location of the master host can migrate between the current master host and one of the shadow master hosts at any time. Therefore, the location of the master host should be transparent to the user.

With a text editor, open the sge-root/cell/common/act_qmaster file.

The name of the current master host is in the file.

Displaying a List of Execution Hosts

To display a list of hosts that are configured as execution hosts in your cluster, use the following commands:

% qconf -sel
% qconf -se hostname
% qhost

The qconf -sel command displays a list of the names of all hosts that are currently configured as execution hosts. The qconf -se command displays detailed information about the specified execution host. The qhost command displays status and load information about the execution hosts.

See the host_conf(5) man page for details on the information displayed using qconf. See the qhost(1) man page for details on its output and other options.

Displaying a List of Administration Hosts

Use the following command to display a list of hosts with administrative permission:

% qconf -sh

Displaying a List of Submit Hosts

Use the following command to display a list of submit hosts:

% qconf -ss
