NAME
qmon - X-Windows OSF/Motif graphical user interface for Grid Engine
SYNTAX
qmon [options]
DESCRIPTION
Qmon allows administrators and users to manipulate the Grid Engine system from an X-Window environment.
Qmon provides various dialogues linked together in multiple ways. For each task the user wishes to
accomplish via qmon a corresponding dialogue is provided. There are multiple ways to address the proper
dialogue for a certain task:
• The qmon main window that comes up first on start-up contains icon buttons for all major
administrative and user tasks. A functionality tooltip is displayed when pointing at the different
icons.
• A Task pulldown menu button appears in the qmon main window menu bar. Clicking on it opens a list of
available tasks. Selecting one of them opens the corresponding dialogue.
• The Task pulldown menu also contains the key accelerators which can be used to invoke the task
dialogues directly from the main window by pressing a certain sequence on the keyboard.
• While navigating through a certain dialogue and its dialogue sub-hierarchy, links to other dialogues
occur whenever a connection between both dialogues is obvious. Pushing the buttons that identify the
links opens up the other dialogues.
OPTIONS
The supported options are the standard X Toolkit options as described in X(1) section Options.
Furthermore, qmon supports:
-cmap Installs a private color map for qmon. This is sometimes useful if other applications have
already allocated lots of colors and if qmon, therefore prints corresponding error messages. Note,
however, that using a private color map will result in color map switches whenever you enter or
leave qmon windows.
-fontFamily {big|medium|small}
Notifies qmon to use different size font families for different resolution sizes.
-help Displays usage information.
-nologo
Startup without logo.
DIALOGUES
Job Control
The Job Control dialogue provides a folder of tabulated lists of the still pending jobs, already running
jobs and recently finished jobs. The dialogue allows for detailed information on the jobs as well as for
the deletion and suspension of jobs being selected. In addition the job control dialogue offers links to
the Submit dialogue in order to submit new jobs or to change attributes of pending jobs (Qalter button).
The fields displayed in the tabular display and the jobs displayed can be customized by pressing the
Customize button. This customization can be saved to the ~/.qmon_preferences file and is used on
following startup for the initial configuration of the Job Control dialogue.
Queue Control
The Queue Control dialogue with its sub-dialogue hierarchy enables the user to control the status of the
Grid Engine queues actually configured in the system and allows the administrator to add new queues or to
modify or delete existing ones. The Queue Control dialogue shows a tabbed view of Cluster Queues or their
corresponding Queue Instances in a tabular way.
By pushing the Add, Clone or Modify button, a sub-dialogue for configuring Grid Engine queues is opened.
A queue needs to be selected to use the clone and modify operation. The configuration sub-dialogue allows
for definition of the queue and its attributes. The configuration sub-dialogue contains in the upper
section the queue name and a list of hosts or hostgroups for which this queue contains the configuration.
The lower section contains a list of hosts or hostgroups at the left, where the default attributes are
shown when the "@/" entry is highlighted. These default attributes can be overruled on a hostgroup or
host basis by enabling attributes and changing their values after this hostgroup or host entry has been
added in the "Attributes for Host/Hostgroup" listbox. The queue configuration parameters (see
queue_conf(5)) are subdivided into different categories (General Configuration, Execution Methods,
Checkpointing, Load/Suspend Thresholds, Limits, Complexes, User Access, Project Access, Subordinate
Queues, Owners) which are selectable by the tab widget area presented in the lower region of the queue
configuration sub-dialogue. The administrator may select previously-configured settings from already
existing queues (Clone button). By pushing the Ok button, the definitions are registered with
sge_qmaster(8). The Queue Control dialogue can be customized in a similar way as the Job Control
dialogue. The settings applied here are also saved in ~/.qmon_preferences.
Submit
The Job Submission dialogue serves for submitting batch and interactive jobs and is also invoked when
changing attributes of pending jobs from the Job Control dialogue explained above (Qalter button). To
toggle between batch and interactive jobs please use the Batch/Interactive button at the top of the
button column on the right side of the Job Submission screen.
The dialogue consists of a folder containing two job preparation dialogue pages. The most frequently used
parameters in the course of a job submission are offered on the General page. A job script has to be
defined; all other fields are optional. If the job demands specification of advanced requirements, the
Advanced tab can be used to switch to an enhanced parameter display.
If resource requirements are mandatory for the job, the Request Resources icon button has to be used to
pop up the Requested Resources sub-dialogue. This sub-dialogue allows for selection of the required
resources of the job and for definition of the quantities in which this resources are to be provided. The
Available Resources are constituted from those complex attributes declared requestable (see complex(5)
for details). Resource requirements can be made Hard, i.e. they must be met before a job can be started
in a queue, or Soft, i.e. they are granted on an as-available basis.
Closing the Requested Resources sub-dialogue with the done button books the specified requirement for the
job. Pushing the Submit button on the top level Submit dialogue submits the job.
Complex Config
The Complex Config allows the administrator to add new complex attributes or to modify or delete existing
ones (see complex(5)). The complex configuration dialogue provides a tabulated list of the complex
attribute entries and an input region for the declaration of new or modified entries. The Add button
updates the tabulated list with a new attribute. The Modify button changes a highlighted existing entry.
The Delete button removes the highlighted attributes. The Load and Save buttons allow saving or
reloading the whole attribute list to or from file. The Ok button registers the additional or modified
complex attributes with sge_qmaster(8).
Host Config
Four types of host related lists can be maintained via the Host Config dialogue:
Administration Hosts
Submit Hosts
Host Groups
Execution Hosts
The host list to be manipulated is selected via clicking at one of the tabs named correspondingly. The
first two host lists only provide for adding or deleting entries, thereby allowing administrative or
submit permission for the hosts on the lists, or denying it otherwise respectively. The host group list
allows the manipulation of host groups. Host groups can reference either other host groups or hosts. The
execution host list entries in addition provide the ability to define scaling factors for the load
sensors, consumable complex attributes and access attributes (access, xaccess and projects, xprojects) as
described in complex(5). CPU, memory and I/O usage reported for running jobs can be scaled in addition
and the relative performance of a host can be defined with the Resource Capability Factor (see
host_conf(5)).
Cluster Config
This dialogue maintains the cluster global configuration as well as host specific derivatives (see
sge_conf(5)). When opened, the dialogue displays a selection list for all hosts which have a
configuration assigned. The special name "global" refers to the cluster global configuration. By pushing
the Add/Modify button a sub-dialogue is opened, which allows for modification of the cluster
configuration. For host specific configurations the 'global' host specific configuration fields are set
insensitive and only the allowed parameters can be manipulated.
Scheduler Config
The Scheduler Configuration dialogue provides the means to change the behavior of the Grid Engine
scheduler thread part of sge_qmaster(8) process. The dialogue contains a representation for all
scheduler configuration parameters as described in sched_conf(5). It is subdivided in the two sections
General Parameters and Load Adjustments, which can be selected via the corresponding tabs. The Ok button
registers any changes with sge_qmaster(8).
Calendar Config
The Calendar Config allows the administrator to add new calendars or to modify or delete existing ones
(see calendar_conf(5)). The dialogue offers a selection list for the existing calendars and displays the
configuration of the one being selected. By pushing the Delete button, the selected calendar is deleted
from the configuration. Pushing the Add/Modify button will open a calendar configuration dialogue, which
allows to create new calendars or which provides the means to change the existing ones. The Ok button
registers the additional or modified calendar with sge_qmaster(8).
User Config
User permissions are controlled via the User Config dialogue. The tab widget in the left section of the
dialogue allows for selecting between
Configuration of Manager accounts.
Configuration of Operator accounts.
Definition of Usersets.
Definition of User accounts.
Those user accounts added to the list of manager or operator accounts are given permission to act as
managers or operators respectively when accessing Grid Engine under their own account.
The userset lists are used together with the user_lists and xuser_lists host, queue, project and cluster
configuration parameters (see queue_conf(5), project(5) and sge_conf(5)) to control access of users to
hosts, queues, projects and the entire cluster. A userset is just a collection of user names and UNIX
group names. Group names are identified by prefixing them with a "@" sign. The already-defined usersets
are displayed in a selection list. These lists can be modified, and new lists can be created, using the
Userset definition dialogue.
Usersets can be used as Access List and/or as Department required for the so called Functional Policy and
Override Policy (see Ticket Config below).
User names can be added to the system as entries to the Grid Engine user database (see user(5)); here a
default project can be attached to the user too. This can be done with the User sub-dialogue.
The Tickets button in the button list on the right side of the dialogue opens the Ticket Config dialogue
(see below).
PE Config
Parallel environment (PE) interfaces can be configured with this dialogue. PE interfaces are necessary
to describe how parallel programming environments like PVM (Parallel Virtual Machine), MPI (Message
Passing Interface), or shared memory parallel systems, are to be instantiated and to impose access
restrictions onto the PEs. When the dialogue is opened a list of the configured PEs is displayed,
together with the current configuration (see sge_pe(5)) of the selected PE interface. To add new PE
interfaces, or to modify existing ones, an Add and a Modify button are available which open a PE
interface configuration sub-dialogue. After applying the changes and quitting this sub-dialogue with the
OK button, the new or modified PE interface is registered with sge_qmaster(8).
Checkpoint Config
Checkpointing environment interfaces can be configured with this dialogue. Checkpointing environments
are necessary to describe the attributes which the different checkpointing methods and their derivatives
on various operating system platforms supported by Grid Engine have. When the dialogue is opened a list
of the already configured checkpointing environments is displayed together with the current configuration
(see checkpoint(5)) of the selected checkpointing environment. To add new checkpointing environments, or
to modify existing ones, an Add and a Modify button is available which opens a checkpointing environment
configuration sub-dialogue. After applying the changes and quitting this sub-dialogue with the OK button,
the new or modified checkpointing environment is registered with sge_qmaster(8).
Ticket Conf
This dialogue offers an overview and editing screen for allocating tickets to the share-based, functional
and override scheduling policies.
The Deadline Job button opens the User Conf dialogue box. Please change to the Userset sub-dialogue and
select the userset named "deadlineusers". Only users of this userset may submit deadline jobs.
The Share Tree Policy button opens the dialogue for creating and editing the Grid Engine share tree (see
share_tree(5) and sched_conf(5) for a description of the configuration parameters).
The Functional Policy button opens the dialogue for creating and editing the allocation of the functional
shares (see sched_conf(5), access_list(5), project(5), queue_conf(5) and user(5) for a description of the
different types of functional shares and the configurable weighting parameters).
The Override Policy button opens the dialogue for creating and editing the allocation of override tickets
(see access_list(5), project(5), queue_conf(5) and user(5) for a description of the different types of
override tickets).
Project Conf
This button opens a dialog for creating projects.
The dialogue offers a selection list for the existing projects and displays the configuration of the one
being selected. By pushing the Delete button, the selected project is deleted from the configuration.
Pushing the Add/Modify button will open a project configuration dialogue, which allows creating new
projects changing existing ones. Project configuration in essence means giving or denying access to a
project for usersets (see User Conf above as well as project(5)). The Ok button registers the additional
or modified project with sge_qmaster(8).
Browser
The Object Browser dialogue's purpose is manifold: First of all, Grid Engine and qmon Messages, such as
notification of error or success concerning a previously taken action, can be displayed in the dialogue's
output window. Also the standard output and the standard error output of qmon can be diverted to the
Object Browser output window.
Additionally the Object Browser can be used to display continuous information about Grid Engine objects
as the mouse pointer moves over their representation as icons or table entries in other qmon dialogues.
Currently, only the display of the configuration of two Grid Engine objects in two separate dialogues is
supported:
• Queue configurations are displayed as soon as the mouse pointer enters a queue icon in the top level
Queue Control dialogue (see above). This facility is activated by pushing the Queue button in the
Object Browser dialogue.
• Detailed job information is printed as soon as the user moves the mouse pointer over a line in the Job
Control dialogue (see above) assigned to a running or pending job.
• Additionally job scheduling information is displayed in the browser if the Why? button in the Job
Control dialogue is pressed. In this case the Browser dialogue is opened implicitly and any scheduling
related information is displayed.
Exit
The Exit icon button is not linked with a dialogue. Its sole purpose is to close all active qmon
dialogues and to exit the application.
RESOURCES
The available resources, their meaning and the syntax to be followed in order to modify them are
described in the default qmon resource file (see the section Files below for the location of the resource
file).
ENVIRONMENT VARIABLES
SGE_ROOT Specifies the location of the Grid Engine standard configuration files.
SGE_CELL If set, specifies the default Grid Engine cell. To address a Grid Engine cell qmon uses
(in the order of precedence):
The name of the cell specified in the environment variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
SGE_DEBUG_LEVEL
If set, specifies that debug information should be written to stderr. In addition the
level of detail in which debug information is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8) is expected to listen for
communication requests. Most installations will use a services map entry instead to
define that port.
SGE_LOAD_AVG Specify a load parameter (see load_parameters(5)) to use instead of load_avg when
displaying/selecting load values.
RESTRICTIONS
If the line to be entered in an editing window is longer than the width of the window, then the text just
runs off the end of the window.
